A lock cylinder assembly includes a housing, a first cylinder disposed within a first bore formed in the housing, and a second cylinder disposed within a second bore formed in the housing, in which at least one of the first and second cylinders is an electronic cylinder. The lock cylinder assembly further includes first and second cams, in which each of the first and second cams are configured to actuate a door lock mechanism. The first cam is directly connected to the second cylinder so as to be rotatable with the second cylinder. The second cylinder and the second cam are rotatable with respect to each other so that the second cam does not rotate with the second cylinder. The second cam is rotatably coupled to the first cylinder so that the second cam rotates when the first cylinder is rotated.

Described herein is locking apparatus, method for making a locking apparatus, and method for mounting a locking apparatus to the door of a personal storage container. The locking apparatus may include a threaded portion having deformed threads and a lock body shape to fit a restrictive mounting hole.

A door lock system includes a shaft and a cam. The cam is supported on the shaft for rotation with the shaft, and for movement along the shaft throughout a range of door lock release locations. A selector engages the cam to move the cam along the shaft upon rotation of the selector. An actuator lock has a closed condition blocking rotation of the shaft, and has an open condition permitting rotation of the shaft. The actuator lock prevents rotation of the cam at any of the door lock release locations when the actuator lock is in the closed condition.

A lock cylinder (110) is provided adapted to be installed in a lock (100) comprising a lock bolt (120) for driving the lock bolt. Said lock cylinder comprises a cylinder housing (200), and a revolving plug (115) comprising a rotor element (275) adapted to rotate with respect to the cylinder housing about a rotation axis (R) within a rotation support (510; 520), and a driving tooth (280) for the lock bolt comprising an engage portion (282) adapted to engage the lock bolt, said driving tooth being rotatable about the rotation axis together with the rotor element and being coupled to the rotor element in such a way the operative distance between the engage portion of the driving tooth (280) and the rotation axis (R) varies, while rotating about the rotation axis, as a function of the rotation angle of the rotor element (275) with respect to the cylinder housing (200). When the lock cylinder (110) is installed in the lock, said operative distance has one among a plurality of first values when the rotation angle of the rotor element belongs to a first angular interval (A I) corresponding to a position of the engage portion of the driving tooth that is proximal to the lock bolt (120); and said operative distance has one among a plurality of second values when the rotation angle belongs to a second angular interval (A2) corresponding to a position of the engage portion of the driving tooth that is distal to the lock bolt, each of said first values being higher than each of said second values. When the lock cylinder (110) is installed in the lock (100), the lock cylinder is located below the lock bolt along a first direction (y) substantially perpendicular to the rotation axis (R). the driving tooth (280) is slidingly housed within a seat (550) which is radially provided in the rotation element (275) and which defines at least one side opening of the rotor element (275) perpendicular to the rotation axis (R).—The driving tooth (280) is provided with at least one engage element (590) which protrudes from a side opening along a direction parallel to the rotation axis, and adapted to slidingly engage guide profiles (524, 620) provided on the rotation support (510; 520), said guide profiles (524, 620) defining for said at least one engage element (590) an overall guide profile having an eccentric shape arranged to support from below along said first direction said at least one engage element (590)

A padlock with an associated locking mechanism is configured for use in a lock configured to be locked and unlocked by a key. The locking mechanism includes a lock cylinder with a key-receiving end configured to interface with the key and further includes a cam positioned at an axial end of the lock cylinder opposite the key-receiving end thereof. The cam is integrally connected thereto thereby restricting axial and rotational motion of the cam with respect to the lock cylinder and can be used to retain components of the locking mechanism (such as tumblers and springs) in the lock cylinder.

An interchangeable electro-mechanical lock core for use with a lock device having a locked state and an unlocked state is disclosed. The interchangeable electro-mechanical lock core may include a moveable plug having a first position relative to a lock core body which corresponds to the lock device being in the locked state and a second position relative to a lock core body which corresponds to the lock device being in the unlocked state. The interchangeable electro-mechanical lock core may include a core keeper moveably coupled to a lock core body. The core keeper may be positionable in a retain position wherein the core keeper extends beyond an envelope of lock core body to hold the lock core body in an opening of the lock device and a remove position wherein the core keeper is retracted relative to retain position to permit removal.
