Disclosed are various embodiments of lock devices, systems, and methods. A lock of the application can include an internal mechanism to permit backdriven operation and lost motion operation. In one form the lock can be made from an assembly of parts that have locating features that require one way installation/assembly. The lock can include an internal power source capable of driving electronics used to determine handedness of a door.

The pushbutton combination lock has a lock bolt mechanism with a lock bolt movably mounted on a frame between a locking position and an unlocking position. The lock bolt mechanism further has two lock bolt actuating mechanisms arranged to move the lock bolt between the locking position and the unlocking position. The lock has a pushbutton combination locking mechanism for locking the first lock bolt actuating mechanism to prevent the lock bolt from being moved by the first lock bolt actuating mechanism to the unlocking position while the second lock bolt actuating mechanism is independent from the pushbutton combination locking mechanism. The pushbutton combination locking mechanism is further rotatably or slidably mounted to the frame such that the user can choose the side for locking and the side for free operation.

The present disclosure defines a lever handing apparatus that permits simplified changing of the handing of a lever handle between a left hand and a right hand orientation. The lever handing apparatus includes an assembly with a rotatable spring cage housing and lever spindle that can be selectively rotated within an escutcheon housing to change the handing position of a lever arm. The handing orientation of the lever can be repositioned without removing a back plate or accessing internal components positioned within the escutcheon housing assembly.

A locking device that can be mounted into a rotating or swinging door is disclosed. The locking device can have a deadbolt. The locking device can detect the position of the deadbolt and/or whether the door is closed. The locking device can have a camera, microphone and speaker. The locking device can send images detected by the camera and audio detected by the microphones to a remote computer.

A lock device with an electric locking function includes a latch head slideably mounted in a case and an unlatching mechanism mounted in the case. The unlatching mechanism includes a follower portion operatively connected to the latch head. The unlatching mechanism further includes a locking mechanism having an electric driving device for driving a locking block to move between a front position in which the unlatching mechanism is locked and a rear position in which the unlatching mechanism is not locked. Wire or wireless control can be provided to control a driving shaft of the electric driving device to move in a forward direction or a reverse direction to lock or unlock the latch head.

Anti-vandalism padlocks are used to secure chains, latches or similar elements, consisting of two coupling armours, with a particular geometry according to their application, with a tumbler cam lock. This padlock does not have an exposed shackle nor any other similar element which may be subject to violation either by cutting, lever movements or the like.
