| A '''lock''' is a device used to restrict access to an area or enclosure. It is the duty of the lock to restrict access until the correct [[Key|key]] or [[Combination|combination]] is used to operate the lock. Most modern locks are a combination of a [[Cylinder|cylinder]] and a [[Bolt|bolt]]. There several major types of locks with many high security locks being hybrid designs.

| == Lock Designs ==
| |
| | |
| ; [[Axial|Axial/Tubular]]
| |
| : A pin-tumbler based design with pins arranged in a circle and accessible from the face of the lock.
| |
| | |
| ; [[Combination]]
| |
| : 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|safes]] or combination padlocks. Combination locks range from low to high security.
| |
| | |
| ; [[Dimple]]
| |
| : A pin-tumbler based design that uses a horizontal keyway rather than the traditional vertical style. High-security dimple locks have various security features that most traditional pin-tumblers don't. Namely, the use of [[Telescoping_pin|telescoping pins]].
| |
| | |
| ; [[Disc_detainer|Disc-detainer]]
| |
| : 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. | |
| | |
| ; [[Electronic_lock|Electronic]]
| |
| : A lock that is operated via electronic means. Electronic locks may incorporate various digital access control features, such as [[Biometrics|biometrics]]. Electronic locks usually provide advanced auditing and key control capabilities, but generally are not any more secure than traditional locks. Many electronic locks are also combination locks.
| |
| | |
| ; [[Hybrid]]
| |
| : Hybrid locks encompass combinations of all lock designs. Many modern high security locks are hybrid designs.
| |
| | |
| ; [[Lever]]
| |
| : Uses flat metal tumblers (levers) with a gate. Lever locks range from low to high security. One of the oldest lock types, next to warded.
| |
| | |
| ; [[Pin_tumbler|Pin-tumbler]]
| |
| : Uses moving pins to prevent rotation of the [[Plug|plug]]. Pin-tumbler locks range from low to high security. [[Dimple]] and [[Axial|axial/tubular]] locks are simply pin-tumblers with modified designs. Currently the most popular lock design worldwide.
| |
| | |
| ; [[Wafer]]
| |
| : 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.
| |
| | |
| ; [[Warded]]
| |
| : Uses internal wards to obstruct the rotation of incorrect keys. One of the oldest lock designs, but provides minimal security by modern standards.
| |
| | |
| == Lock Types == | |
| | |
| ; [[Cam_lock|Cam Lock]]
| |
| : A lock that uses the cam or [[Actuator|actuator]] as the bolt mechanism. | |
| | |
| ; [[Cylinder|Cylinder]]
| |
| : A lock that uses a rotating cylinder to actuate the locking bolt.
| |
| | |
| ; [[Padlock]]
| |
| : A lock that uses a self-recessed bolt or shackle and is not mounted to a door or wall. Many padlocks use a cylinder-based lock design.
| |
| | |
| == Locking Bolt Mechanisms ==
| |
| | |
| :''See [[Bolt]] or [[Latch]].''
| |
| | |
| == Compromise of Locks ==
| |
| | |
| 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 as a hobby is known as [[Locksport|locksport]].
| |
| | |
| ; [[Lockpicking]]
| |
| : Internal components are manipulated to allow the lock to be opened.
| |
| | |
| ; [[Bypass]]
| |
| : The non-cylinder portions of the lock are attacked, such as the locking [[Bolt|bolt]] or the [[Actuator|actuator]].
| |
| | |
| ; [[Impressioning]]
| |
| : A working key is duplicated or internal components are manipulated to provide a working key. | |
| | |
| ; [[Decoding]]
| |
| : The proper position of internal components is decoded via examination of the key or manipulation of internal components.
| |
| | |
| ; [[Destructive_Entry|Destructive Entry]]
| |
| : Destruction of or damage to the lock or surrounding materials, such as a door or wall. Also known as forced entry.
| |
| | |
| ; Robbery/Violence
| |
| : The proper key or combination is foricbly obtained from authorized users by threatening or inflicting physical or emotional harm.
| |
| | |
| ; Deception
| |
| : The proper key or combination is obtained via theft, impersonation, blackmail, or fraud.
