<div>=Locks=<br />
A lock is a device used to restrict access. It is the duty of the lock to restrict access until the correct key, whether it is a combination, electronic signal, or a tradional physical key is used to operate the lock. Modern locks may incorporate various digital access control features, such as [[Biometrics|biometrics]]. There several major types of locks with many modern high security locks being hybrid designs.<br />
<br />
== History ==<br />
Add to me!<br />
<br />
== Lock Designs ==<br />
<br />
;[[Combination]]<br />
:A keyless lock that uses numbers, letters, or symbols for input. A specific combination of input properly aligns internal components so that the lock can be opened. Most commonly associated with [[Safe|safe]] locks, or locks found on school lockers. Combination locks range from low to high security.<br />
<br />
;[[Disc_detainer|Disc-detainer]]<br />
:Uses flat metal tumblers that interface with a [[Sidebar|sidebar]] to prevent rotation of the plug. Separate from wafer designs because discs are usually rotated rather than lifted.<br />
<br />
;[[Electronic_lock|Electronic]]<br />
:A lock that is operated via electronic means. Electronic locks provide advanced auditing and key control capabilities, but generally are not any more secure than traditional locks.<br />
<br />
;[[Hybrid]]<br />
:Hybrid locks encompass combinations of all lock designs. Many modern high security locks are hybrid designs.<br />
<br />
;[[Lever]]<br />
:One of the oldest lock types, next to warded. Uses flat metal tumblers (levers) with a gate. The levers are actuated by the key, and once aligned properly allow the bolt to be actuated. Lever locks range from low to high security.<br />
<br />
;[[Pin_tumbler|Pin-tumbler]]<br />
:Originally invented by the Egyptians, modernized by [[Linus_Yale|Linus Yale]]. Currently the most popular lock design worldwide. Uses moving pins to prevent rotation of the [[Plug|plug]]. Pin-tumbler locks range from low to high security. [[Dimple|dimple]] and [[Axial|axial/tubular]] locks are simply pin-tumblers with modified designs.<br />
<br />
;[[Wafer]]<br />
:Uses flat metal tumblers to prevent rotation of the plug. Wafer locks range from low to high security, with the vast majority of wafer locks being low security.<br />
<br />
;[[Warded]]<br />
:One of the oldest lock designs; uses internal wards to obstruct the rotation of incorrect keys. Warded locks provide minimal security by today's standards.<br />
<br />
== Locking Bolt Mechanisms ==<br />
<br />
;Deadbolt<br />
:A locking bolt that is held in place by end pressure. Traditionally a square shape, but may also be a claw or hook. Extremely popular in residential and commercial usage.<br />
<br />
;Latch/Spring<br />
:A spring-biased locking bolt. May be used as the locking mechanism padlocks, namely low security or [[Warded|warded]] padlocks. Popular in residential usage.<br />
<br />
;Padlock Shackle<br />
:A steel shackle detained by ball bearings or a spring-biased protrusion. Shackles without a double-locking system are usually susceptible to [[Bypass|shimming]].<br />
<br />
;Cam<br />
:A lock that uses the [[actuator]] as the locking bolt. Popular on vending machines and file cabinets.<br />
<br />
== Compromise of Locks ==<br />
<br />
Security of locks can be compromised many ways, depending on the type, manufacturer and model, and the installation and maintenance details of a target lock. The practice of compromising locks for entertainment is known as [[Locksport|locksport]].<br />
<br />
;[[Lockpicking]]<br />
: Internal components are manipulated to allow the lock to be opened.<br />
<br />
;[[Bypass]]<br />
: The non-cylinder portions of the lock are attacked, such as the locking [[Bolt|bolt]] or the bolt [[Actuator|actuator]].<br />
<br />
;[[Impressioning]]<br />
: A working key is duplicated or internal components are manipulated to provide a working key.<br />
<br />
;[[Decoding]]<br />
: The proper position of internal components is decoded via the key or manipulation of components.<br />
<br />
;[[Destructive_Entry|Destructive Entry]]<br />
: Destruction of the lock or surrounding materials, such as a door or wall.<br />

<div>Thanks to cppdungeon for creating this page!<br><br />
I think it would be better if we just put a quick note on the lock types and link to their main page. Eventually, we'll have so much info that they'll get their own pages, anyways. Just the history of each type alone will be enough to warrant an individual page.<br><br />

not sure how this discussion thing works exactly, but i think the definition of lock needs to be broadened<br><br />

== Locks ==<br />
A lock is a device used to actuate or control access. The actual lock rarely holds anything shut--that is the duty of the bolt or latch the lock controls. Most locks have keys that are used to operate the lock, while some have combinations or electronic sensors that unlock the lock. There several major categories of locks, based on design. Some locks incorporate extra security features, but still fall under a general umbrella category. The types are pin-tumbler, wafer, lever, combination (wheel) and combination (dial).<br />
<br />
<br />
== pin-tumbler ==<br />
Pin-Tumbler locks are commonly found in padlocks and doors. Some have keys oriented so the thin part of the key interacts with the pins. These are simply called pin-tumbler. Some have keys oriented so that the flat side of the key interacts with the pins. These are called dimple locks, because the "cuts" in the key are dimples in the flat side of the key.<br />
<br />
== wafer ==<br />
Wafer locks behave a lot like pin-tumbler locks, only instead of pins, they have flat disks with holes in the center. These disks are placed in grooves in a plug, on top of springs. When the lock is locked, some tumblers protrude from the plug, into a groove in the cylinder, blocking the rotation. when the correct key is inserted, the disks retract into the plug so that it can rotate.<br />
<br />
<br />
== Lever ==<br />
Lever locks are operated by simultaneously raising several levers to the right height. Each lever has a gate cut in it. The bolt has a stump that goes through each gate. when locked, it the stump will be on one side of the gate; when unlocked on the other side. The key actually moves the bolt while raising the levers.<br />
<br />
<br />
== combination (wheel) ==<br />
more to come. examples: safe locks with dials, cheap master locks at schools<br />
<br />
<br />
== combination (dial) ==<br />
more to come. examples: luggage locks, bike locks<br />
