A lock system includes first, second, and third covers. The first cover includes a first wall, a second wall, a first latch feature, and a second feature. The first wall extends in a first direction. The second wall is coupled to the first wall and extends in a second direction transverse to the first direction. The second cover extends in a third direction and includes a third latch feature configured to receive the first latch feature. The third cover extends in a fourth direction and includes a fourth latch feature configured to receive the second latch feature.

The magnetic anti-tampering system of the magnetically enhanced key and lock system provides a mechanical and magnetic security system. It utilizes a modified paracentric key and a locking assembly affixed to a component inside of a paracentric lock. The magnetically enhanced key and lock system increases the security of a pair centric lock by defeating the unauthorized operation of pair centric locks by unauthorized users, such as inmates, who have fabricated copies of the authentic, paracentric keys. Paracentric locks and keys are the most common type of locks used in jails, state prisons, and detention facilities. The locking system requires that both the teeth of the key and the magnetic pairs of the key and locking dog combine to open the lock.

A lock system includes a first housing and a lock bolt. The first housing includes a recessed area and a first opening disposed within the recessed area. The lock bolt is supported by the first housing and configured to move between a first position and a second position. The lock bolt extends beyond the recessed area in the first position. The lock bolt is disposed within the recessed area in the second position. The lock bolt blocks the first opening in the first position and the second position.

A locking device can include a lock housing; a first carriage attached to a first guided member and a second guided member; a locking bolt having a first portion that is slidably retained within the first carriage; a first extension spring connecting an upper portion of the first carriage to an upper portion of the locking bolt; a second extension spring connecting a lower portion of the first carriage to a lower portion of the locking bolt; wherein: the carriage can be actuated to move from at least a first position to a second position within the lock housing, the carriage can be be actuated to move from at least the second position to the first position within the lock housing. The first and second extension springs can be constructed and arranged to absorb any impact applied to the locking bolt.
