The '''Stanley Vidmar''' lock is a [[pin-tumbler]] lock designed for industrial and commercial use. It was introduced in 1964 and is used primarily in Stanley Vidmar's modular storage systems and tool cabinets. The lock is known for its durability, simplicity, and unique keyways that resist unauthorized duplication.

The Stanley Vidmar Lock is a traditional pin-tumbler design integrated into a [[cam lock]] system. Turning the key rotates a cam to secure or release a compartment. It has been widely used in environments requiring reliable and tamper-resistant locking mechanisms.

__TOC__

== Principles of Operation ==

The Stanley Vidmar Lock uses five or six pin stacks in a standard pin-tumbler configuration. When the correct key is inserted, the pins align at the shear line, allowing the plug to rotate. This rotation actuates the cam mechanism at the back of the lock, which secures or releases the storage unit.

The lock's design includes a unique keyway profile, making unauthorized key duplication more difficult. It is built with hardened components to resist forced entry and drilling.

== Disassembly Instructions ==

Disassembly of the Stanley Vidmar Lock is straightforward and follows standard procedures for pin-tumbler locks:

{{Pin-tumbler standard disassembly}}

'''Steps:'''

Remove the Retaining Clip or Nut: Located at the back of the cylinder.
Withdraw the Cylinder: Push or pull the lock cylinder out of its housing.
Access the Pin Stacks: Use a plug follower to remove the plug without displacing the pins.

The '''TuBAR''' is a [[sidebar|dual-sidebar]] lock made by [[CompX|CompX Chicago]]. It is distinguished for being one of the few [[cam lock]]s to use a [[sidebar]] without major modifications to the sidebar mechanism. The TuBAR was originally produced by Chicago Lock Co., which has since become CompX Chicago.

The TuBAR is easy to identify because of the visible pins arranged in two rows of four in the center of the plug. The TuBAR is commonly mistaken for an oddly arranged [[tubular]] [[Pin_tumbler |pin-tumbler]] lock.

__TOC__

== Principles of operation ==

The TuBAR uses eight pins arranged in two rows of four down the vertical length of the keyway. Each pin has a tapered end surrounded by a spring at the bottom of the pin chamber. Two sidebars are used at 3 and 9 o'clock in the [[plug]], and each set of four pins uses a different sidebar. When the correct key is used, each pin is moved so that it's true gate is lined up with the sidebar, allowing the sidebar to retract and the plug to rotate. The sidebar is a two piece assembly of a bar and a crescent. The flat part of the crescent enters the gates on the pins while the bar restricts plug movement until the sidebar is retracted.

There are seven positions for true gates, at 0.025" increments between 0.175" and 0.325" from the tip of the pin. Each pin has one or more false gates which are too shallow to allow the sidebar to retract. The false gates provide resistance to [[lockpicking]] attacks. The high spring tension on pins pushes each sidebar into the cylinder walls; the sidebars have no independent spring mechanism.

Above the plug a profiling cap is used to make sure the key is inserted properly. The TuBAR is warded so that the key can only be inserted in one orientation. The profile cap is free-spinning and helps provide resistance to drilling attacks, too. <ref>{{Ref pulford}}</ref> When the plug is rotated the key is held in place by a protrusion that goes through a hole in the blade.

File:Tubar_pins_close.jpg|Closeup of false and true gates on each pin.
File:Tubar_sidebar_aligned.jpg|True gates of each pin properly aligned.
</gallery></div>

== Construction ==

The cylinder is sintered steel, and the [[plug]] brass. The pins, sidebar components, and profile cap are made of hardened steel. The [[key]] is made of steel with a plastic bow.

== Disassembly instructions ==

The TuBar is relatively easy to disassemble.

# Tap out and remove the retaining rod at the rear of the cylinder.
# Push the [[plug]] and profile cap out of the cylinder.

== Vulnerabilities ==

The TuBAR may be vulnerable to the following attacks:

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

'''Notes'''
* Visual decoding of the true gates of deep-setting pins can be done with the naked eye.

Kwikset Titan

2024-06-18T13:54:26Z

TheCre8r: Updating Source to Internet Archive

=Kwikset Titan=

|name=Kwikset Titan
|Img=File:Kwikset_Titan_cylinder.jpg

}}

The '''Titan''' is a [[pin-tumbler]] lock made by [[Kwikset]]. It is a modified version of the [[Kwikset Classic]] that uses six pins instead of five, and has a slightly different key to accommodate this. The KW10 keyway used by the Titan is nearly identical to the KW1 keyway; but it has an additional slot at the top, allowing for the insertion of the longer KW10 key.

The Titan is slowly being phased out(?) by the [[Kwikset SmartKey]] due to concerns over [[key bumping]].

__TOC__
<br clear="all">

== Principles of operation ==

:''See also: [[Pin-tumbler#Principles_of_Operation|Pin-Tumbler (Principles of Operation)]]''

The Titan is a traditional pin-tumbler that uses six pin stacks. To open the lock, all pin stacks must be aligned at the [[shear line]] to allow the [[plug]] to rotate. There are six key pin heights and seven key cut depths with the use of [[Master keying|master pins]]. The Titan has a [[MACS]] of 4. Many Classic cylinders come with [[construction keying]] dimples on the plug.

The Titan uses the same Classic key pins that are slightly tapered on both ends. Neither Classic nor Titan cylinders require the use of [[security pin]]s but often contain a couple of spool drivers.

|}

== Disassembly instructions ==

The Titan can be disassembled with standard pin-tumbler disassembly. The design of the pin-chamber casing facilitates quick disassembly and full rekeying.

{{Pin-tumbler standard disassembly}}

==== Removing cylinders from Kwikset knobs ====

# Using the Cylinder Removing Tool, rotate the round spindle until the tab lines up with the bolt stems.<ref>[https://web.archive.org/web/20160425201825/http://www.kwikset.com/Libraries/Literature/Rekeying_Manual.sflb.ashx 2004 Kwikset Rekeying Manual]</ref>
# Slide the tool under the spring housing behind the spindle and push to release the retainer. Pull out the spindle without rotating it.
# Slide the tool into the empty spindle chamber, angling it to bypass the cover at the top of the hole. Push the tool all the way in and apply pressure until the cylinder is forced out of the front of the knob.

== Vulnerabilities ==

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

* [[Lockpicking]]
* [[Bumping]]
* [[Impressioning]]
* [[Decoding]]

'''Notes'''
* Though far less than on the classic, poor tolerances with the Titan allow [[tryout keys]] to work.

}}

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.

Master Lock No 4

2019-03-14T00:36:28Z

TheCre8r: /* Master Lock No. 4 */ Fixed Image Link

= Master Lock No. 4 =

{{Lock model
| name = Master Lock No. 4
| Img = File:MasterNo4.jpg
| Img_size = 150px

The '''No. 4''' is a [[pin-tumbler]] [[padlock]] made by [[Master Lock]]. The No. 4 uses a laminated brass padlock body with an internal key-in-knob-style [[cylinder]]. The inner cylinder uses four pin stacks and does not use any [[security pin]]s.

The No. 4 is a common low security padlock used in the United States.

__TOC__
<br clear=all>

== Principles of operation ==

The No. 4 cylinder is a [[pin-tumbler]] lock with four pin stacks and no [[security pin]]s. The cylinder typically uses the [[M1]] [[Key#Types_of_Keys|key profile]] but may use other profiles, as well. The standard No. 4 can be opened in both directions but the "commercial" series body restricts opening to clockwise rotation. The No. 4 is not a [[key retaining]] padlock.

== Disassembly instructions ==

The No. 4 cannot be disassembled non-destructively. To disassemble it the rivets that hold the laminated body together must be removed and each layer removed individually. The inner cylinder itself can be disassembled in the same manner as a traditional pin-tumbler lock:

{{Pin-tumbler standard disassembly}}

'''Notes'''
* The No. 4 cylinder requires a small diameter plug follower.
* The No. 4 plug is retained by a crimp, rather than a C-clip or [[cam]]. Above are the generic pin-tumbler disassembly instructions.

== Vulnerabilities ==

The No. 4 is vulnerable to a wide range of attacks. The reduced pin tumbler count and poor manufacturing tolerances makes it an easy lock to pick. It's commonly given to [[locksport]] beginners as a "confidence lock"; a lock that is easy to open and inspires you to continue picking. The No. 4 may be vulnerable to one or more of the following:

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

Junkunc

TheCre8r: /* Junkunc */ Added link to combination lock to remove it from being a dead-end page

=Junkunc=

'''John Junkunc''' was a railroad employee who had a habit of losing keys. He then designed and made a [[combination |combination lock]] so he could avoid the problem of losing keys.

One of his early versions next to a quarter for scale:

File:Junkunc small combination padlock 2.JPG| Unlocked
File:Junkunc small combination padlock 3.JPG
</gallery></center>

These early Junkunc combination padlocks had gates that lined up directly with the shackle. If someone were to try decoding the combination like a modern lock by pulling the shackle while dialing, the 'wheels' would become deformed as well as the shackle.

Normally, this problem can be identified by a dial that binds and is very hard to turn at a certain point, but turns freely for the rest of the dial rotation. (Similar to a bent spindle on a safe lock).
