A reprogrammable lock cylinder including a stator, a rotor rotatably mounted in the stator, a tumbler assembly mounted in the rotor and operable to permit rotation of the rotor when a first key is inserted into the rotor, the tumbler assembly having a reprogramming state in which the tumbler assembly is operable to be reprogrammed by a second key to match the second key, and an insert configured to cause the tumbler assembly to adopt the reprogramming state in response to presentation of a magnetic tool to the rotor, and to prevent the tumbler assembly from adopting the reprogramming position in absence of the magnetic tool.

Embodiments of the present invention are directed to merchandise display systems and methods for displaying an article of merchandise. In one example, the system includes a sensor configured to be secured to the article of merchandise. The system also includes a base configured to removably support the sensor thereon. The base includes a lock mechanism configured to lock the sensor to the base.

A bridge tumbler lock has tumblers that both slide and pivot, with their motion controlled by pairs of key interfaces. A sidebar is released to permit lock opening movement when all tumblers are in their correct positions. This results in a lock that is resistant to release of information due to partially correct key combinations occurring in the course of a lock picking attempt and thus enables enhanced security in an economical, effective lock construction.

A rekeyable lock cylinder with a cylinder body and a rotatable plug assembly is provided. The plug assembly includes a plurality of key followers and a corresponding plurality of racks for operation of a first locking bar. Additionally, the plug assembly includes a plurality of sliders for operation of a second locking bar. The key followers and racks can be rekeyed while the plug assembly is disposed within the cylinder body. The sliders are operated by a side milling cut on a key and provide additional key cut combinations for enhanced security of the rekeyable lock cylinder.
