'''Binding''' is a fundamental principle of [[lockpicking]] and [[impressioning]] that allows components to be manipulated in order to affect entry. Binding uses [[tension]] to determine the order in which components should be picked, or, in the case of impressioning, the spots in which a key should be filed.
 
Binding is also used defensively by locks to prevent the lock from opening without the correct [[key]]. Components like [[Sidebar|sidebars]] and [[Security_Pin|security pins]] prevent the lock from opening through the use of binding themselves against various parts of the lock, preventing rotation.
 
__TOC__
 
== In lockpicking ==
 
The type of binding that occurs during lockpicking is depends on lock design, the lock components (pins, wafers, discs, etc) and the lock body. In [[cylinder]] based locks, binding is caused by the cylinder and [[plug]] shearing into components. Binding not only determines the order in which components are picked, but also holds them in position so that they can be individually manipulated.
 
; [[Pin_tumbler|Pin-tumbler]] and [[Wafer]] locks
: Binding occurs between pins or wafers, cylinder, and plug.
 
; [[Lever]] locks
: Binding occurs between the levers and the [[bolt]], stump, or fence.
 
; [[Disc_detainer|Disc-detainer]] locks
: Binding occurs between the discs and the [[sidebar]].
 
;  [[Combination]] locks
: In direct-drive rotary combinatino locks, binding occurs between the combination wheels and the fence. Also applicable to many low-security combination [[Padlock|padlocks]] where the shackle binds with the wheels.
 
== In impressioning ==
 
[[Impressioning]] uses binding to freeze components in place so that a blank key can be used to determine proper position of components. Almost all impressioning techniques apply extreme tension to bind all components in the lock then use a blank key to obtain impressions. This is true for pin-tumbler, wafer, lever, and disc-detainer locks.
