A locking device is provided including a housing, a barrel, an interchangeable core (IC), and a prong driver. The housing extending along a longitudinal axis and including a first slot. The barrel slidably disposed in a hollow interior of the housing, where the barrel is slidable along the longitudinal axis. The barrel including a second slot and a hollow interior to retain the IC. The IC including a key hole and coupled to the prong driver. The prong driver including an engaging element extending from the prong driver perpendicularly to the longitudinal axis into the first slot and the second slot. When a proper key is inserted into the key hole and rotated, the engaging element is rotated within the first and second slots to allow the barrel to slide along the longitudinal axis to lock and unlock the locking device.

A key device (10) includes a generally elongate shaft portion (12), and at least one magnetic key combination element (20) disposed in the shaft portion (12), which is rotatable about a rotation axis (22).

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.

In one aspect of the present disclosure, a locking device is provided including an interchangeable core (IC), a barrel, an anti-rotation plate, a prong driver, a bolt and a backplate. The barrel is coupled to the backplate and includes a hollow interior to receive the IC. The bolt is slidably disposed in a slot of the backplate. The IC includes a key hole. The prong driver is coupled to the IC and the bolt, such that, when a proper key is inserted into the key hole and rotated the bolt can be extended from the slot in a direction away from the locking device or retracted into the slot in a direction toward the interior of the locking device. The anti-rotation plate of the locking device is coupled to the barrel to prevent the locking device from being rotated relative to a structure the locking device is mounted to.

An improved locking device comprising a lock body, a locking plug, and a plurality of tumblers, wherein the tumblers are restricted from moving with respect to the locking plug during the time frame that the locking plug is rotated with respect to the lock body.

A locking system has a lock housing having first pin slots, a lock cylinder having second pin slots and being supported within the lock housing such that rotation of the lock cylinder is dependent upon a position of tumbler pins within the pin slots, and an idler block defining a keyway to receive a deviated key in which the idler block is rotatable relative to the lock cylinder between an entry position and a pin position aligning the key with the pin slots. One or more translating shields in the idler block are movable from an open position in which the keyway is unobstructed by the shield to allow for insertion or removal of the deviated key and a closed position in which the translating shield protrudes at least partway into a path of the keyway without interfering with rotation of the deviated key with the idler block.

Articles of manufacture, machines, processes for using the articles and machines, processes for making the articles and machines, and products produced by the process of making, along with necessary intermediates, directed to a lock and key system.

A pin tumbler cylinder lock that is virtually pick proof comprises a cylinder housing having a single bore and a cylinder key plug arranged in the single bore. The pin tumbler cylinder lock also comprises a cavity having a predetermined shape in a predetermined portion of the housing. The pin tumbler cylinder lock also includes a lockout sleeve arranged over the cylinder key plug wherein the lockout sleeve may rotate within the cavity to create a lockout mode for the pin tumbler cylinder lock when a lock picking attempt is occurring thereon.
