The '''Exec''' is a [[disc-detainer]] lock made by [[Abloy]]. The Exec uses between 9 and 11 discs that interface with a [[sidebar]]. It is a modified version of the [[Abloy Disklock]] that includes a Disk Steering System (DSS) designed to protect against [[lockpicking]]. Unlike the Disklock, the Exec only allows the key to be turned one direction. As such, it is primarily used in [[padlock]]s and [[cam lock]]s. The Exec model uses an 'H' shaped keyway.

The Exec is a newer form of the [[Abloy Profile]] and [[Abloy Disklock]]. It has since been superceded by the [[Abloy Protec]].

__TOC__

== Principles of operation ==

{{imbox|text=Abloy literature refers to the plug as the "cylinder" and the cylinder as the "housing". Lockwiki uses the traditional terms to avoid confusion.}}

The Exec works by using angled bitting cuts on the key to properly rotate discs. The key is inserted and rotated 90°; the angled cuts on the key in rotate the discs in the lock. If all the discs are rotated to the correct position the sidebar can fall into the discs and the [[plug]] can be rotated. Washers are placed between discs to ensure that the key rotates each disc individually. The main advantage of the Exec is the use of a Disk Steering System (DSS) that requires the key to be fully inserted before the plug can rotate. This is the precursor to the Disk Blocking System (DBS) used in the [[Abloy Protec]].

There are six positions available for discs (designated 0-5), at 18° increments between 0° and 90°. In an eleven disc lock, there are 10,077,696 (6<sup>9</sup>) theoretical key [[differs]]. Two of the eleven discs are always 0 cuts that control the Disk Steering System.

Discs provide manipulation resistance in the form of false gates. In addition, they may use a modified cut-out shape to deter the use of improperly shaped tools.<ref>Fey, Han. 2005. [http://toool.nl/images/f/f3/Abloypart2.pdf Evolution of Abloy (part 2)].</ref> The first disc in the lock is made of hardened steel and is free-floating. This provides drill resistance as well as [[lockpicking]] resistance.

The Disk Steering System (DSS) works with two dimples on each side of the key blade. When the key is fully inserted two sliding pieces inside the plug are pushed into the key. This allows the plug to rotate as well as prevents the key from being removed when the plug is rotated.

The sidebar is L shaped to prevent drilling and removal attacks.

'''Notes'''
* The first disc (hardened steel) is always a 1 cut (90°).
* Master keying is made possible by multiple true gates cut on each disc.

== Key security levels ==

;Red (Factory restricted)
: Keys are only available from Abloy directly.

;White (Customer restricted)
: Keys are available from specific Abloy Exec dealerships.

;Blue (Dealer restricted)
: Keys are only available through Abloy dealerships. A [[security card]] is required to duplicate keys.

== Disassembly instructions ==

Disassembly of the Abloy Exec is fairly simple, though it has more parts than previous models. Care must be taken to ensure that removal of the discs is done properly. Discs ''cannot'' be flipped around and the order of washers must be preserved to ensure proper function once reassembled.

Medeco M3

{{Lock model

}}

The '''M3''' (or '''m<sup>3</sup>''') is a [[UL 437]] rated [[pin-tumbler]] lock made by [[Medeco]]. The pin tumblers use [[axial rotation]] to interface with a [[sidebar]] located at 3 o'clock in the [[plug]]. It also features a spring biased slider that restricts movement of the sidebar until properly positioned. The M3 is easily identified by the "m<sup>3</sup>" logo to the left of the keyway.

It is called the M3 because it is the third generation of Medeco's axial rotation system, following the [[Medeco Original]] and [[Medeco Biaxial]] designs. The M3 provides enhanced master keying capabilities when compared with previous models, but does not provide a significant security increase. The M3 slider component is also used in the [[Medeco Bilevel]].

__TOC__

== Principles of operation ==

:''See also [[Medeco Biaxial#Principles_of_operation|Medeco Biaxial (Principles of Operation)]]''

The M3 uses five or six pin-tumblers that provide [[axial rotation]] to interface with a [[sidebar]].

The M3 sidebar differs from previous models because it has small grooves cut out where the slider arms fit into. Functionally, it is the same as other Medeco sidebars; pin tumblers are properly rotated by the correct key and the sidebar legs can interface with the gates on each pin-tumbler.

The M3 slider is a spring-biased component located under the sidebar. In its default state, the slider arms block the sidebar from retracting. A protrusion on the right side of the key pushes the slider into the correct position and allows the sidebar to retract. Sliders and M3 keys may be master keyed to allow a variety of protrusions to properly position the slider, but the final resting position of the slider is always the same.

</gallery></div>

'''Notes'''
* Original and Biaxial sidebars are ''not'' compatible with the M3.

== Disassembly instructions ==

The M3 is disassembled in the same way as a normal pin-tumbler cylinder, with consideration for the sidebar and the slider. It is recommended the sidebar be removed before removing the slider.

{{Pin-tumbler standard disassembly}}

== Vulnerabilities ==

The M3 was initially thought of as an improvement to the [[Medeco Biaxial]] that allowed for enhanced key control and pick resistance. Continued research by the [[locksport]] community has shown a wide variety of attacks are possible, some of which are made possible by design changes in the M3 itself. The M3 may be vulnerable to one or more of the following:

* [[Lockpicking]]
** The M3 slider can be easily compromised with a paper clip, [[Picks|lockpick]], or similar object. For this reason it is not considered an effective security enhancement.
** The Medecoder tool can be used to properly rotate bottom pins once the slider has been compromised.<ref>King, Jon. [http://www.theamazingking.com/medecoder.html Medecoder].</ref>
* [[Decoding]]
** The Medecoder tool (among others) can be used to decode the sidebar bitting code of non-ARX pins.
* [[Bypass]]
** Widening of the M3 keyway to accomodate the slider allowed for various bypass attacks on M3 locks produced before 2008.
* [[Key bumping]]<ref>{{Ref Tobias OpenIn30}}</ref>
* Key simulation

Medeco Original

2010-10-01T13:20:04Z

TecknicalTom: adding pages to the "Lock models" category

=Medeco Original=

{{ Lock model
| name = Medeco Original
| Img = File:Medeco_Original_cylinder.jpg

| lock_design = [[Pin-tumbler]], [[Sidebar]]
| years_produced = 1968-Present

}}

The '''Original''' is a [[UL 437]] rated [[pin-tumbler]] lock made by [[Medeco]]. It is well known for the use of rotating bottom (key) pins that interface with a [[sidebar]]. The Original has the distinction of being the first pin-tumbler lock to use [[axial rotation]], and is the basis for most other Medeco mechanical locks since. It was previously thought to be one of the most secure locks available, but continued research from the [[locksport]] community has proven a variety of attacks are possible, including [[key bumping]].

The Original has since been superceded by the [[Medeco Biaxial]] and [[Medeco M3]].

__TOC__

== Principles of Operation ==

The Medeco Original uses five or six pin-tumblers that provide [[axial rotation]] to interface with a sidebar located at 3 o'clock. Pin-tumblers must be properly raised to the shear line as well as rotated so that the sidebar arms can fall into notches on the side of each pin-tumbler. Axial rotation is provided by the design of the bottom (key) pins and angled bitting cuts on the key. There are 6 depths available for pin-tumblers, allowing 7,776 (6<sup>5</sup>) theoretical key [[differs]] in a five pin Original (excluding the sidebar).

The sidebar interfaces with notches on the bottom pins. Bottom pins must be properly rotated so that their true notches interface with the sidebar arms. The Original uses three different rotations:

<div align="center">
{| class="prettytable"
|-
! Type || Left || Center || Right
|-
! Fore (Biaxial)
| K || B || Q
|-
! Original
| L || C || R
|-
! Aft (Biaxial)
| M || D || S
|}</div>

This allows for 243 (3<sup>5</sup>) and 729 (3<sup>6</sup>) sidebar differs in five and six pin Originals, respectively.

The Original uses 2-3 mushroom top pins in each cylinder to provide manipulation resistance to traditional [[lockpicking]]. The sidebar notches on the sides of the bottom pins may also have false notches to resist manipulation by rotation. In addition, "ARX" pins are used to protect against manipulation by rotation. ARX pins close the sidebar notches before they reach the end of the pin, making it so they cannot be readily grabbed by a tool.

Resistance to forced entry is provided in the form of hardened steel rods and discs. In the plug rods are in the 3, 9, and 12 o'clock positions. In the cylinder, two crescent shaped discs are placed at the 12 and 3 o'clock positions to protect the pin-chambers and the sidebar. As a secondary locking mechanism, the sidebar itself also helps to protect against a variety of forced entry techniques. Bottom pins may also have a hardened steel core to resist drilling.

<div align="center"><gallery>
File:Medeco Original keys.jpg|Five and six pin Original keys.
</gallery></div>

'''Notes'''
* Original and Biaxial bottom pins are not interchangeable. They are identified by the position of the flag that limits rotation. The flag is 90° from the true gate in the Original and 180° in the Biaxial.

== Disassembly instructions ==

Disassembly of the Original is simplified compared to other sidebar-based locks because there are no additional finger pins used in the sidebar.

{{Pin-tumbler standard disassembly}}

'''Notes'''
* When reassembled the sidebar must be pointed down, with the ball bearing facing the front of the plug.

== Vulnerabilities ==

* [[Lockpicking]]
* [[Decoding]]
* [[Impressioning]]
* [[Key bumping]]

'''Notes'''
* The validity of key bumping attacks against Medeco cylinders has been debated between Medeco and the [[locksport]] community. Research done by Marc Weber Tobias and Tobias Bluzmanis has shown these systems are vulnerable to a wide variety of attacks, including bumping.
* Lockpicking attacks against this lock were previously thought extremely difficult due to axial rotation. A tool called the "Medecoder", developed by Jon King, made this process much easier and at the same time allowed for decoding of the sidebar code.<ref>King, Jon.

Fichet 480

=Fichet 480=

{{Lock model
|name = Fichet 480
|Img = File:Fichet_480_cylinder.jpg
|maker = [[Fichet]]
|lock_type = [[Cylinder]]
|lock_design = [[Wafer]]
|years_produced = 1949 - 19??
|patent = [http://www.google.com/patents/about?id=O_MyAAAAEBAJ US 4,044,578]<br>[http://www.google.com/patents/about?id=D9YBAAAAEBAJ US 4,296,618]
|related = [[Fichet 787]]
}}

The '''480''' (or '''450''', '''481''', '''482''', '''483''', '''484''') is a [[wafer]] lock made by [[Fichet]]. It uses ten wafers and two [[sidebar]]s as locking components. While technically a normal wafer lock, the 480 uses an interesting design that improves security and longevity of both the [[key]] and lock. The 480 is easily identified because of the H shaped keyway. The various models of this lock can be identified by the style of key bow and minor differences in the design and placement of internal components.

The 480 was originally thought to be a strong lock, but it is no longer produced because of a [[#Vulnerabilities|design vulnerability]] that allowed the cylinder to be forcibly opened using a hardened blank key.

The 480 has since been superseded by the [[Fichet 787]].

__TOC__

== Principles of operation ==

{{imbox|text=Fichet/locksmith literature may also refer to wafers as "rockers" due to the way they work. Lockwiki uses the traditional terms to avoid confusion.}}

The 480 uses a rather unique wafer design with 10 wafers and two sidebars. Five wafers and one sidebar are located on each side of the lock in the 3 and 9 o'clock positions.

Each wafer is held in place by a retaining rod that extends through the plug. When the key is inserted, the wafers rotate around the rod and interface with the sidebars. The wafers sit on top of a capped spring which pushes them into their default position. A ball bearing is placed below the wafer, in the keyway, to interface with the key itself. The key never directly touches the wafers, instead it uses the ball bearing to move them. This reduces wear and makes use of the key smoother.

The key itself has a H shaped profile and four active bitting surfaces. The key is ''not'' symmetrical and may only be inserted in one orientation.

Manipulation resistance is provided in the form of false gates on the wafers.

</gallery></div>

== Disassembly instructions ==

The 480 is relatively easy to diassemble, but it has many small parts that might cause problems. Remember to maintain the order of components as they are removed from each side of the lock. Components must be returned to the correct side when the lock is reassembled for proper function.

# Remove the [[cam]] or C-clip and withdraw the [[plug]].
# Remove the sidebars and sidebar springs.
# With a flathead screwdriver, remove the plug faceplate.
# Place the plug in a vise with one set of wafers facing up. With a hammer and a small flathead screwdriver, lightly tap (from the back of the plug) the retaining rod out. When the retaining rod is removed the wafers, springs, caps, and ball bearings can all be removed. Be careful to remove the rod only when the wafers are facing up, otherwise all the components will spill out.
# Repeat for second set of wafers.

== Vulnerabilities ==

The 480 may be vulnerable to one or more of the following:

* [[Lockpicking]] (''A special tool is available for picking the 480, though traditional tools may also be used.)<ref>[http://protectvol.online.fr/484.html Cylindre Fichet 480-484 (French)]</ref>''

}}

The '''Abloy Classic''' is a [[disc-detainer]] lock made by [[Abloy]]. The Classic uses between 5 and 11 discs that interface with a [[sidebar]]. Designed in 1907 by Emil Henriksson, it is distinguished as being the first disc-detainer lock design. Classic models are easily identified because they use a half circle ("D" shape) keyway. The Classic has since been superseded by many other models, the latest of which is the [[Abloy Protec]].

__TOC__

== Principles of operation ==

{{imbox|text=Abloy literature refers to the plug as the "cylinder" and the cylinder as the "housing". Lockwiki uses the traditional terms to avoid confusion.}}

The Classic works by using angled bitting cuts on the key to properly rotate discs. The key is inserted and rotated 90°; the angled cuts on the key in rotate the discs in the lock. If all the discs are rotated to the correct position the sidebar can fall into the true gates and the [[plug]] can be rotated. Washers are placed between discs to ensure that the key rotates each disc individually.

There are six positions available for discs, at 18° increments between 0° and 90°. In an eleven disc lock, there are 362,797,056 (6<sup>11</sup>) theoretical key [[differs]].

Discs provide manipulation resistance in the form of false gates. In addition, they may use a modified cut-out shape to deter the use of improperly shaped tools.<ref>Fey, Han. 2004. [http://toool.nl/images/5/58/Abloy.pdf Discs make the difference.]</ref> The first disc in the lock is made of hardened steel and is free-floating. This provides drill resistance as well as [[lockpicking]] resistance.

'''Notes'''
* The first disc (hardened steel) is always a 0 cut (90°). The PL3020 padlock uses a brass first disc.
* Master keying is made possible by multiple true gates cut on each disc.
* The sidebar may be round (round true gates) or L shaped (square true gates). Modern Abloy designs use the L shaped sidebar, with the exception of the PL330C padlock and cam locks. The "L" shape prevents drilling and removal of the sidebar without drilling through the entire disc pack.

== Disassembly instructions ==

Disassembly of the Abloy Classic is fairly simple, though care must be taken to ensure the discs, washers, and sidebar are removed properly. Discs ''cannot'' be flipped around and the order of washers must be preserved to ensure proper function once reassembled.

Schlage Everest

|related=[[Schlage Primus]]
}}

The '''Everest''' is a [[pin-tumbler]] lock made by [[Schlage]]. It uses six pin-tumblers and a single [[side pin]] as locking components. The Everest is notable because of the security implications of the side pin. It is commonly referenced in [[locksport]] literature as an example of defeating security of auxilliary locking mechanisms. The Everest has since been superseded by the [[Schlage Primus]].

__TOC__

== Principles of operation ==

The Everest functions much like a traditional pin-tumbler cylinder, but with the addition of the side pin. There are 6 pin-tumblers with 10 depths each, a total of 1,000,000 (10<sup>6</sup>) theoretical key [[differs]]. The side pin is on the bottom of the plug in the 5 o'clock position. It is spring biased into the cylinder, and prevents rotation of the plug in this position. The side pin is a static size and ''all'' Everest keys will lift the side pin to the correct position. The side pin does not check to see if it was overlifted, much like the early Egyptian pin-tumbler locks.

== Disassembly instructions ==

The Everest is diassembled in the same way as a traditional pin-tumbler lock, with consideration for the side pin. Like the finger pins in many [[sidebar]] locks, the side pin will be driven out of the exposed plug when there is no key inserted.

{{Pin-tumbler standard disassembly}}

== Vulnerabilities ==

All Everest keys have the same side pin bitting. Any key blank with the proper keyway profile can be used to make a working key or a [[Bumping|bump key]]. This also means that any Everest key may be filed in half and used to neutralize the side pin. The modified key can also be used to provide [[tension]].<ref>Blaze, Matt. 2003. [http://www.crypto.com/photos/misc/everest/ Notes on Schlage Everest Locks].</ref> The side pin can also be picked manually, if need be.

}}

The '''Biaxial''' is a [[UL 437]] rated [[pin-tumbler]] lock made by [[Medeco]]. It is well known for the use of rotating bottom (key) pins that interface with a [[sidebar]]. The Biaxial is one of the most widely used American [[high security locks]]. It was previously thought to be one of the most secure locks available, but continued research from the [[locksport]] community has proven a variety of attacks are possible, including [[key bumping]].

The Biaxial is a newer version of the [[Medeco Original]] and has since been superseded by the [[Medeco M3]]. The [[Medeco Duracam]] is a [[dimple]] lock form of the Biaxial.

__TOC__

== Principles of Operation ==

The Medeco Biaxial uses five or six pin-tumblers that provide [[axial rotation]] to interface with a sidebar located at 3 o'clock. Pin-tumblers must be properly raised to the shear line as well as rotated so that the sidebar arms can fall into notches on the side of each pin-tumbler. Axial rotation is provided by the design of the bottom (key) pins and angled bitting cuts on the key. There are 6 depths available for pin-tumblers, allowing 7,776 (6<sup>5</sup>) theoretical key [[differs]] in a five pin Biaxial (excluding the sidebar).

The main difference between the Biaxial and the Original is that Biaxial bottom pins sit be'''fore''' or '''aft'''er the center of the bitting cut. This allows for six total positions of the bottom pins, but pins use only three true gate positions. Biaxial pins have their own rotation codes:

<div align="center">
{| class="prettytable"
|-
! Type || Left || Center || Right
|-
! Fore (Biaxial)
| K || B || Q
|-
! Original
| L || C || R
|-
! Aft (Biaxial)
| M || D || S

There are 6 total positions for bottom pins, allowing 7,776 (6<sup>5</sup>) and 46,656 (6<sup>6</sup>) total sidebar differs in five and six pin Biaxials, respectively. True gates on the pins can only be rotated to three positions, so there are only 243 (3<sup>5</sup>) and 729 (3<sup>6</sup>) actual rotational differs in five and six pin Biaxials.

The Biaxial uses 2-3 mushroom top pins in each cylinder to provide manipulation resistance to traditional [[lockpicking]]. The sidebar notches on the sides of the bottom pins may also have false notches to resist manipulation by rotation. In addition, "ARX" pins are used to protect against manipulation by rotation. ARX pins close the sidebar notches before they reach the end of the pin, making it so they cannot be readily grabbed by a tool.

Resistance to forced entry is provided in the form of hardened steel rods and discs. In the plug rods are in the 3, 9, and 12 o'clock positions. In the cylinder, two crescent shaped discs are placed at the 12 and 3 o'clock positions to protect the pin-chambers and the sidebar. As a secondary locking mechanism, the sidebar itself also helps to protect against a variety of forced entry techniques. Bottom pins may also have a hardened steel core to resist drilling.

'''Notes'''
* Biaxial and Original bottom pins are not interchangeable. They are identified by the position of the flag that limits rotation. The flag is 90° from the true gate in the Original and 180° in the Biaxial.
* The Biaxial can be identified by the the Biaxial logo (a split circle) to the left of the keyway.

== Disassembly instructions ==

Disassembly of the Biaxial is simplified compared to other sidebar-based locks because there are no additional finger pins used in the sidebar.

{{Pin-tumbler standard disassembly}}

'''Notes'''
* When reassembled the sidebar must be pointed down, with the ball bearing facing the front of the plug.

== Vulnerabilities ==

The Biaxial may be vulnerable to one or more of the following:

* [[Lockpicking]]
* [[Decoding]]
* [[Impressioning]]
* [[Key bumping]]

'''Notes'''
* The validity of key bumping attacks against Medeco cylinders has been debated between Medeco and the [[locksport]] community. Research done by Marc Weber Tobias and Tobias Bluzmanis has shown these systems are vulnerable to a wide variety of attacks, including bumping.
* Lockpicking attacks against this lock were previously thought extremely difficult due to axial rotation. A tool called the "Medecoder", developed by Jon King, made this process much easier and at the same time allowed for decoding of the sidebar code.<ref>King, Jon.

}}

The '''Twin Combi''' (or '''Combi''', '''Max''', '''Twin Multi''', '''Twin 5800''') is a [[pin-tumbler]] lock made by [[ASSA]]. The Combi is part of the Twin series of locks that use pin-tumblers and a [[sidebar]] to provide two layers of security. The sidebar in the Combi is the first in the Twin series (historically) to require that finger pins be raised and rotated properly. Later systems that include this principle are the [[ASSA Twin V-10]] and the [[ASSA Twin Maximum]].

The Combi is similar in function to the [[Schlage Primus]] cylinder.

__TOC__

== Principles of operation ==

The Combi uses six pin-tumblers and five sidebar finger pins. The top (driver) pins use single and double-spool designs. Counter-milling in the plug chambers works with the spool pins and provides a high level of pick resistance. There are 9 depths available for bottom (key) pins, and four depths available for top (driver) pins. Top and bottom pins are combined to provide a balanced (uniform height) pin stack that resists attack from [[decoding]], [[comb pick]]s, and reduces wear on the springs. In total, there are 531,441 (9<sup>6</sup>) theoretical key differs for the pin-tumbler portion of the lock.

The sidebar, located in the 8 o'clock position, is pushed out by two springs. The sidebar bitting on the key raises finger pins which interface with the sidebar. Pins must be raised and rotated properly for the sidebar to retract. Finger pins can be positioned in two heights and three rotations for a total of 7,776 (2<sup>5</sup>*3<sup>5</sup>) theoretical sidebar differs. Manipulation resistance for finger pins is provided in the form of serrated pins, with serrations running vertically down the entire pin.

The cylinder and plug use a variety of hardened steel inserts to protect against [[forced entry]]. In the plug, steel rods are located at the 9, 12, and 3 o'clock positions. In the cylinder, three rods are located in front of the pin chambers at the 12 o'clock position. Rods near the third pin chamber in the plug and cylinder are also common.

'''Notes'''
* The Twin 1800 is a less expensive form of the Combi that uses fewer (3) sidebar pins.
* The pin-tumbler bitting code is referred to as the ''system code'', and the sidebar bitting code as the ''sidebar code''.

== Disassembly instructions ==

The Combi is disassembled in the same way as a traditional pin-tumbler cylinder. The sidebar does not cause too many problems when the plug is removed. When the key is removed from the exposed plug the finger pins will be forced out by spring pressure.

{{Pin-tumbler standard disassembly}}

== Vulnerabilities ==

The Combi system may be vulnerable to one or more of the following:

* [[Lockpicking]]
* [[Impressioning]]
* [[Decoding]]
* [[Bumping|Key bumping]]

'''Notes'''
* Bumping is possible given a bump key with the correct sidebar bitting.

KABA Gemini

TecknicalTom: adding pages to the "Lock models" category

=KABA Gemini=

{{Lock model
| name = KABA Gemini
| Img = File:KABA_Gemini_cylinder.jpg
| maker = [[KABA]]
| lock_type = [[Cylinder]]
| lock_design = [[Dimple]], [[Pin-tumbler]]
}}

The '''KABA Gemini''' is a [[UL 437]] rated [[dimple]] lock designed by [[KABA]] and manufactured by the Lori Corporation of Connecticut, USA. The Gemini uses three rows of dimple pins oriented at 4, 8, and 12 o'clock in the [[plug]]. The Gemini is one of the few pure [[pin-tumbler]] locks that is protected against [[key bumping]] by design.

The [[Sargent KESO]] lock is functionally equivalent to the Gemini.

__TOC__

== Principles of operation ==

The Gemini functions like a standard dimple lock, but it has three sets of active pin-tumblers. The key is bitted on the sides and edges of the blade and is reversible. The lock itself is a combination of cylinder and inner core, with a core retaining screw at 1 o'clock.

Bottom pins are lightly spooled to deter [[lockpicking]], and mushroom bottom pins are available. Factory standards dictate 2-4 mushroom pins be used in each cylinder. The 4 and 8 o'clock pin chambers in the lock (and cuts on the key) are slanted upward at a 15 degree angle. This helps prevent against [[key bumping]] and unauthorized duplication. There are 6 six chambers in the 8 o'clock position and 5 in the 4 o'clock position. Both have four pin depths available for bottom (key) pins. There are three depths and 10 positions available for pins in the 12 o'clock chambers, but the first position (nearest the bow) is not used. Positions 3, 5, 7, and 9 are used in traditional systems, and 2, 4, 6, 8, and 10 in [[master key]] systems.<ref>Phillips, Bill. ''Locksmithing''. 1999.</ref> In all chambers, balanced top (driver) pins are used to prevent [[decoding]] and the use of [[comb pick]]s.

The Gemini also uses a variety of components to resist [[forced entry]]. Hardened steel rods are placed in the plug at 3, 9, and 12 o'clock, and in the cylinder at 12 o'clock. The core retaining screw itself acts as a defense against various attacks.

<div align="center"><gallery>
File:KABA_Gemini_key.jpg
File:KABA_Gemini_pins_all.jpg
</gallery></div>

'''Notes'''
* Pin chambers are spaced so that rotation does ''not'' allow top pins to fall into the other chambers. However, rotation of the plug without a key inserted allows the pin-tumblers to fall into the keyway.
* Pins are nickel plated via electrolysis to prevent corrosion.

== Disassembly instructions ==

The Gemini is complicated to disassemble because of the several layers between the cylinder and the plug. In addition, the design of the Gemini does not allow a [[plug follower]] to be used until the core is removed from the cylinder.

# Remove the [[cam]] or C-clip.
# Remove the core retaining screw from the cylinder at 1 o'clock.
# Extract the core
# Remove the core's cam/extension piece (if any)
# Slide the core cover off, be careful to not let any springs or pins fall out. Alternatively, use a small diameter plug follower.

'''Notes'''
* In key-in-knob (KIK) cylinders, the bible is screwed into the core. This must be removed before step 5.
* If a plug follower is used in step 6, remember that pin stacks are balanced; complete disassembly may be required.

== Vulnerabilities ==

The Gemini may be vulnerable to the following:

* [[Lockpicking]]
* [[Impressioning]]

'''Notes'''
* The design of the Gemini pins and cylinder prevent [[Bumping|key bumping]] attacks.<ref>Fey, Han & Wels, Barry. What the Hack (2005). [http://wiki.whatthehack.org/images/0/00/BumpkeyPresentatie.pdf Bump Proof Locks]</ref>

The '''Twin V-10''' (or '''V-10''', '''Twin 2''', '''Twin 7000''') is a [[UL 437]] rated [[pin-tumbler]] lock made by [[ASSA]]. The V-10 is part of the Twin series of locks that use pin-tumblers and a [[sidebar]] to provide two layers of security. The V-10 is an updated version of the [[ASSA Twin 6000]] cylinder.

The V-10 is distinct because it is the first of the Twin series to provide geographically distributed sidebar codes to protect against key interchange and unauthorized duplication. It also has a patented key control system that provides a high number of key and sidebar [[differs]].

__TOC__

== Principles of operation ==

The V-10 uses six pin-tumblers and five sidebar finger pins. The top (driver) pins use single and double-spool designs. Counter-milling in the plug chambers works with the spool pins and provides a high level of pick resistance. There are 9 depths available for bottom (key) pins, and four depths available for top (driver) pins. Top and bottom pins are combined to provide a uniform height pin stack that resists attack from [[comb pick]]s as well as reduces wear on the springs. In total, there are 531,441 (9<sup>6</sup>) theoretical key differs for the pin-tumbler portion of the lock.

The sidebar, located in the 8 o'clock position, is pushed out by two springs. The sidebar is interesting because it provides a pre-made set of cuts that must be matched by the finger pins. This contrasts traditional sidebars which have uniform sidebar cuts. In the V-10 system, all finger pins have the same true gates and the key raises them to different positions to match the sidebar. Manipulation protection on the finger pins is provided in the form of false gates above and below the true gate. V-10 finger pins can also be in either the ''for'' (left) or ''aft'' (right) positions. Mono-keyed locks all use the ''for'' position, but [[master key]] systems include both ''for'' and ''aft'' positions. Finger pins can be lifted to five different positions. In total, there are 100,000 ((5*2)<sup>5</sup>) sidebar bittings (3,125 in mono-keyed systems).

The cylinder and plug use a variety of hardened steel inserts to protect against [[forced entry]]. In the plug, steel rods are located at the 9, 12, and 3 o'clock positions. In the cylinder, three rods are located in front of the pin chambers at the 12 o'clock position. Rods near the third pin chamber in the plug and cylinder are also common.

* Older V-10 keys list the direct keyway code on the bow of the key. Newer keys use an indirect code.

The '''EVVA DPS''' ('''Double Profile System''') is a [[pin-tumbler]] lock made by [[EVVA]]. The DPS uses five pin-tumblers and a single [[sidebar]] for key profiling, located at the 4 o'clock position. The '''EVVA EPS''' (Extra/Extended Profile System) model uses six pin tumblers instead.

The '''EVVA DPX''' ('''Double Profile eXtended''') is a newer form of the DPS that provides two key-profiling sidebars in addition to the pin-tumbler components. Sidebars are located on each side of the plug, in the 4 and 8 o'clock positions. The DPX is also marketted as the Mottura PX in Europe.

Both the DPS and DPX have been superseded by the [[EVVA DPI]] to protect against [[Bumping|key bumping]] attacks.

__TOC__

== Principles of Operation ==

The DPS and DPX are traditional pin-tumblers with the addition of a key-profiling sidebar. In the case of the DPX, there are two sidebars that provide key-profiling.

In both cases the pin-tumblers function normally, and profile cuts on the side(s) of the key interface with the sidebar(s). The sidebar is active, and the center portion must be aligned properly or the third driver (top) pin will function as a trap pin when the plug is rotated.<ref>[http://www.evva.at/fileadmin/files_all/Download/Prospekte/DPS_Prospekt_EN.pdf Locking System: DPS]</ref>

The '''EVVA DPI''' ('''Double Profile Integrated ''') is a dual [[sidebar]] lock made by [[EVVA]]. The DPI uses two sidebars; one controlled by five or six spring-biased sliders, and the other by the key profile. The six component version is marketed as the DPI-6. Unlike other locks in EVVA's Dual Profile series, newer models of the DPI cannot be [[bumping|bumped]] because they no longer use [[pin-tumbler]]s. Older models are still vulnerable.

__TOC__

== History ==

Add to me!

== Principles of Operation ==

The DPI is a combination of two sidebars. The first sidebar is controlled by a set of five spring-biased sliders. Sliders provide picking resistance in the form of false cuts. Unlike traditional sidebars which align to the center, sidebar cuts must all align at the top of the sidebar.

The second sidebar is used for key profiling but is not completely passive. Instead, this sidebar is a combination of traditional key profiling with an active moving element in the center. When the plug is rotated, the moving element must be properly positioned or a trap pin at the top of the cylinder will fire and prevent further rotation or removal of the key.

The cylinder and plug have hardened steel rods to protect against [[forced entry]] techniques, namely drilling. (Carbide rods can also be provided upon request)<ref>[http://www.evva.at/fileadmin/files_all/Download/Prospekte/DPS_Prospekt_EN.pdf Locking System: DPS (Double Profile System)]</ref>

The '''3KS''' ('''3 Kurven System''') ('''3 Curve System''') is a high security [[sidebar]]-based lock made by [[EVVA]]. The 3KS is resistant to most [[Locks#Compromise_of_locks|methods of entry]], and is immune to [[Bumping|key bumping]] attacks. It uses two sidebars that interface with six sliders each, as well as a passive key profiling mechanism.

__TOC__

== Principles of Operation ==

The 3KS uses a total of twelve free-floating sliders, two [[sidebar]]s, and a passive profile bar. Sliders are divided into two groups of six, each located on one side of the keyway. Each set of sliders has its own sidebar. The key uses two sets of laser tracks to manipulate single and double pin sliders. The top and bottom of the blade have cuts corresponding the passive key profile bar used in the lock.

When the key is inserted the sliders are guided by the laser tracks of the key. Once fully inserted the profile bar falls onto the top of the key. If the profile and slider cuts are correct the plug can rotate. When the plug is rotated the sidebars are pushed into the key to hold it in place.

Notes:
* There are 9<sup>6</sup>×7<sup>6</sup> total [[differs]].<ref>[http://toool.nl/images/f/f9/Cutaway1.pdf Han Fey (TOOOL NL). May 2005. ''Cutaway Locks'']</ref>
* Double pin sliders have 7 positions, and single pin sliders have 9 positions.
* Key blanks come with the double pin laser track pre-cut; locksmiths only need to add the single pin cut.
* Sliders and sidebars are made of hardened steel and are teflon coated for additional longevity.

== Key Control ==

3KS [[key]]s are patent protected and duplication is restricted. 3KSPlus keys are patent protected until 2025. The laser tracks and other key features make manual duplication difficult. A key [[security card]] is required in order to obtain duplicate 3KS keys.<ref>[http://www.evva.at/products/mechanical-locking-systems/schliesssystem-3ks-3ksplus/technology/en/ Keys: EVVA (3KS, 3KSPlus)]</ref>

== Disassembly instructions ==
The 3KS requires the key be ''removed'' from the cylinder for the plug to be withdrawn. Sliders must me properly centered or they will block removal of the plug, similar to how they block removal of the plug when a key is inserted.

It is much easier to disassemble the 3KS if the cylinder can be removed from its mounting and held so that the keyway is parallel to the ground. This is because sliders need to be positioned in the center of the plug, but also because it prevents the sliders from falling out when the plug is withdrawn.

# Remove the [[cam]] and C clip.
# Hold the cylinder so that the keyway and sliders are parallel to the ground.
# Insert and remove a key. (This centers all sliders)
# Lightly push the back of the plug. If all sliders are centered it should easily withdraw from the cylinder.

== Vulnerabilities ==
The 3KS may be vulnerable to one or more of the following:

* [[Lockpicking]] {{Pick resistance|3|5}}
* [[Decoding]]
* [[Destructive Entry]]

Notes:
* Immune to [[Bumping|key bumping]] attacks. Bumping causes damage to both the key and sliders.
* The top or bottom of a key may be filed off to defeat the key profiling mechanism.

TecknicalTom: minor cleanup

= Master Lock No. 140 =

{{Lock model

| lock_type = [[Padlock]], [[Cylinder]]
| lock_design = [[Pin-tumbler]]
| years_produced =

}}

The '''No. 140''' is a [[pin-tumbler]] [[padlock]] made by [[Master Lock]]. The No. 140 is a solid body padlock. The inner cylinder uses four pin stacks and does contain [[security pin]]s.

__TOC__

== Principles of operation ==

The No. 140 cylinder is a [[pin-tumbler]] lock with four pin stacks and either 1 or more [[security pin]]s. The older versions of this lock had only one spool pin in the 3rd position, but Master Lock changed this so that now the lock has varying amounts in varying locations. The No. 140 can only be opened clockwise.

== Disassembly instructions ==

The No. 140 cannot be disassembled non-destructively. To disassemble it the lock must be sawed in half. Because the lock body is the outer cylinder for this lock, the lock will be nonfunctional if this is done.

== Vulnerabilities ==

The No. 140 is vulnerable to a wide range of attacks. Other than the security pins, the reduced pin tumbler count and poor manufacturing tolerances makes it an easy lock to pick and it is often given to lock picking beginners to learn about security pins. The No. 140 may be vulnerable to one or more of the following:

* [[Lockpicking]]
* [[Key bumping]]
* [[Impressioning]]
* [[Bypass]]
* [[Destructive entry]]

Security pin

2010-09-26T00:14:52Z

TecknicalTom: /* Security Pin */ missing period

=Security Pin=

A '''security pin''' is a modified version of a key or driver pin in a [[pin-tumbler]] lock that makes manipulation more difficult. Security pins are commonly designed to prevent [[lockpicking]], but are also designed to resist [[decoding]], [[impressioning]], [[key bumping]], and other compromise techniques. Similar modifications to components in non-pin locks are also common, with serrated components being the most popular in both [[wafer]] and [[lever]] locks. [[Combination]] and [[disc-detainer]] locks commonly use false gates to prevent manipulation.

__TOC__

== Principles of operation ==

Security pins are designed so that use of a tool other than a key will trigger the pins and lock one or more pins at the [[shear line]]. This can be due to individual manipulation of components or [[tension]] on the cylinder. When triggered, security pins bind between the [[plug]] and [[cylinder]], blocking the rotation of the plug until tension on the cylinder is released and pins are dropped back to their resting position.

== Types of security pins ==

; Mushroom
: A top or bottom pin with a beveled cut around their circumfrence, resembling a mushroom shape. Top pin mushroom designs are much more common, but companies like [[Mul-T-Lock]] use them for bottom pins, as well.

; Spool
: A top pin with a portion of the center removed, resembling a spool or barbell shape. Triggers when the center of the spool is caught at the shear line.

; Serrated
: A top or bottom pin with light serrations around the circumfrence of the pin. Triggers when a serration is caught at the shear line.

; Hybrid
: A combination of the previous three designs. For example, "spoorated" is a spool pin with serrations on the outer edges of the pin.

Pin tumbler

2010-09-25T23:58:44Z

TecknicalTom: /* History */ spelling and grammar

=Pin-tumbler=

[[Image:Lockwiki_Medeco_pins.jpg|thumb|right|text-top|300px|Medeco biaxial key, pin pairs, springs, and chamber caps.]]

A '''pin-tumbler''' is a [[Cylinder|cylinder]] based [[Lock|lock]] design that uses movable pins to prevent rotation of the [[Plug|plug]]. A [[Key|key]] is used to properly elevate pins to allow the plug to rotate and the locking [[Bolt|bolt]] to be retracted.

The pin-tumbler is currently one of the most widely used lock designs in the world. Minor changes to the positions of pin-tumbler components are the basis for [[Dimple|dimple]] and [[Axial|axial/tubular]] lock designs.

__TOC__

==History==

Pin-tumbler locks were originally invented in ancient Egypt. The design used a series of single pins that, when locked, would prevent movement of a bolt by resting inside the bolt itself. The key was used to raise pins out of the bolt, allowing it to retract. This was the first use of a [[Shear_line|shear line]], a major discovery that is the basis for all cylinder based locks in modern use. Early pin tumbler locks, bolts, and keys were all made with wood, but eventually brass and iron were used. Many cultures adopted the design throughout history, but it would not be widely used until [[Linus_Yale_Sr|Linus Yale Sr.]] and [[Linus_Yale_Jr|Linus Yale, Jr.]] modified the pin-tumbler design in the mid 1800s.

Linus Yale Sr. improved the Egyptian design with the idea of pin pairs. In the original lock pins were required to be raised high enough to clear the bolt, but were not checked to make sure they weren't raised higher than necessary. The addition of a second pin in each chamber allowed for [[Positive_locking|positive locking]] when components were raised too high. In this design, the key had to properly raise the pin pairs so that they could separate at the shear line, allowing the locking bolt to be retracted. Yale Sr. also added springs above the pin pairs to force them down to their locked position when no key is inserted.

Linus Yale Jr. continued his father's work by improving the design of the pin-tumbler. He made it smaller, more reliable, and changed the design of the key to be flat instead of fluted. This type of key is still used by modern pin-tumbler locks.

The design of the pin-tumbler lock has remained virtually unchanged since the Yale family's contributions. [[Master_Key|Master keying]] allows the addition of pins in each chamber to provide various methods of keying a particular lock or group of locks. Other improvements have been in the form of auxiliary security mechanisms to prevent compromise. [[Security pin]]s, [[sidebar]]s, and [[side pin]]s were created to frustrate [[lockpicking]]. Other anti-picking modifications exist, such as [[Axial_rotation|rotation]] or [[Telescoping_pin|telescoping]]. Finally, ball bearings and hardened steel rods or discs are now inserted into the plug or cylinder to protect the pin stacks against [[Destructive_Entry|destructive entry]].

== Principles of Operation ==

Pin tumblers are a series of pin stacks pushed down by a spring. Each stack must be properly raised to allow pins to separate at the shear-line. Once all pin stacks are separated the plug can freely rotate and [[Actuator|actuate]] the locking bolt to lock or unlock the lock.

An incorrect key will not align all components correctly; rotation of the plug will be blocked at the shear-line.

</gallery>
</div>

== Components ==

; Key pins (bottom pins)
: The pins that are touched by the key. Key pins are sized differently corresponding to the different depth cuts on the key. When the correct key is inserted, all key pins are aligned at the [[shear line]], allowing the plug to rotate.

; Driver pins (top pins)
: The pins placed between the key pins and the spings. In their resting position, the driver pins block rotation of the plug. In more advanced pin-tumblers, driver pins may be sized inverse to the key pins to defend against [[decoding]] and attacks via [[comb pick]]s.

; Springs
: Springs placed above the pin stacks push pins down to the their resting position, ensuring that pins cannot be trapped above the [[shear line]] while the plug is in the default position.

; Plug
: The [[plug]] is the inner piece of the lock that rotates upon insertion and tension of the correct key. The plug is connected to the cam to actuate the bolt mechanism when rotated.

; Cylinder
: The [[cylinder]] is the outer piece of the lock that houses the upper pin chambers and the plug. Driver pins and springs are trapped in the cylinder's pin chambers when the correct key is used and plug rotated.

; Cam
: The [[cam]] is an extension connected to the back of the plug which actuates the [[bolt]] mechanism to lock or unlock the lock.

== Vulnerabilities ==

Pin-tumblers are vulnerable to a wide variety of attacks. The specifics of the pin-tumbler design and manufacturing tolerances will determine the exact vulnerabilities present, but most pin-tumblers are vulnerable to at least one or more of the following:

* [[Lockpicking]]
* [[Pick_Gun|Pick Guns]]
* [[Bumping|Key Bumping]]
* [[Tryout_Keys|Tryout Keys]]
* [[Comb_Pick|Comb Picks]]

Ingersoll CS700

TecknicalTom: /* Principles of operation */ grammar and spelling fix

=Ingersoll CS700=

{{Lock model
|name=Ingersoll CS700

|maker = [[Ingersoll Rand]]
|lock_type=[[Padlock]]
|lock_design=[[Lever]]
|years_produced=1988-Present
|patent=
|related=
}}

The '''CS700''' (or '''CS712''', '''OS711''', '''Impregnable''') is a [[lever]] lock made by [[Ingersoll Rand]]. It uses ten levers and a spring-biased [[sidebar]] as the primary locking mechanisms. Levers are interspersed to act with a double-bitted key. The CS700 does not use a traditional style lever fence arrangement, and the key resembles a pin-tumbler or wafer style key. The CS700 is easily identifiable by the squiggle shaped keyway that resembles a flattened "w".

The CS700 also comes in a six-lever model known as the '''OS600'''.

__TOC__

== Principles of operation ==

The CS700 uses ten nickel-silver levers that alternate bitting surface in the plug. Each lever uses its own spring (similar to traditional lever locks) and pivots along a common rod located at 6 o'clock. There are four positions available for cuts on each lever, giving the CS700 a total of 1,048,576 (4<sup>10</sup>) theoretical key differs. The only keying constraint is that a bitting depth cannot be repeated more than three times sequentially. This gives the CS700 840 differs per bitting surface, for a total of 705,600 (840<sup>2</sup>) real key differs. The CS700 can be master keyed using widened true gates (gates that accommodate adjacent bittings), or with multiple true gates on each lever.

Keys are double-sided and nonsymmetric. Each bitting area interfaces with five of the levers. Keys are stamped with an indirect key bitting code and require a [[security card]] before they can be duplicated.

== Model variations ==

This lock comes in a variety of models, including traditional mortise and rim deadbolts. There are different padlock models based on the type of shackle protection used, but the internal locking mechanism is identical:

* OS600: Fully exposed shackle, 6 lever version
* OS711: Fully exposed shackle
* CS712: Semi-exposed shackle
* CS700: Closed shackle

== Disassembly instructions ==

# Unlock the padlock with the correct [[key]].
# Remove the retaining screw(s) from the shackle hole.
# Remove the plug from the padlock body.

== Vulnerabilities ==

The CS700 may be vulnerable to one or more of the following:

American Lock 30

| lock_design = [[Pin-tumbler]]

}}

The '''30''' is a [[pin-tumbler]] [[padlock]] made by [[American Lock]]. This is one of the cheaper padlocks American Lock makes. It contains not only security top pins, but security bottom pins as well.

__TOC__

== Principles of operation ==

The series 30 padlock is a standard pin tumbler lock which, though it sometimes has room for a 6th pin stack, comes pinned in 5 chambers. The bottom pins come in both serrated and plain, and the top pins come as spooled, spoorated, and serrated top pins. When all of the pins are lifted to the shear line by the key the plug can turn clockwise. The 30 series often has high tension on the plug and can require more force than normal to turn the plug once it has been picked open.

== Disassembly instructions ==

Once the padlock is opened, the shackle can be turned and a rivet can be hammered out of the lock. This removal of the rivet should drop off the bottom plug retainer allowing the plug to be removed (This cannot be replaced after it has been done). After the plug is out the same standard disasembly applies:
