Tension
Tension (or torque, torsion) is a fundamental lockpicking principle that allows a lock to be compromised by exploiting tolerance errors to defeat each locking component individually. A tool is used to apply tension to the lock while a pick properly position internal components. Once all components are positioned correctly the tension tool may be used to actuate the locking bolt.
Tension tools are commonly referred to as tension bars, tension wrenches, or torque wrenches. Their design varies widely, but is most commonly associated with the L shaped pin-tumbler tension tool. Like picking tools, most tension tools leave forensic evidence in the lock.
Compromise of warded, electronic, and combination locks ususally does not require a tension tool, though a similar tool may be used to actuate the locking bolt.
Pin-tumbler/Wafer Tension Tools
In pin-tumbler, wafer, dimple, and axial locks, tension is applied to the plug of the lock.
Lever Tension Tools
In lever locks, tension is usually applied directly to the bolt, but may vary depending on the design of the lock. In most cases, tension tools resemble the tip of a lever key.
Disc-detainer Tension Tools
In disc-detainer locks, tension is applied to varying parts of the lock, depending on the specifics of the lock.
