A device for preventing unwanted opening of a locked enclosure includes a lock bolt moveable between a locked position and an unlocked position. A face gear is meshable with and rotatable by the worm gear between locking and unlocking positions when the worm gear is driven in the first and second directions, respectively. A blocker member is rotatable between first and second positions. A biasing member is operatively coupled to the face gear and the blocker member to bias the blocker member in a biasing direction. A sliding member selectively disengages the blocker member to allow the blocker member to rotate in the biasing direction. A lever arm is operatively coupled to the sliding member such that the lever arm is in the disengaged and engageable positions when the sliding member engages the blocker member in the first and second positions, respectively.

A hinged object, such as a door, window, gate, lid, etc., comprises a first hinge, a second hinge, and an electromechanical locking device mounted on or in the hinged object. A first electrical wire is embedded in the hinged object that couples the electromechanical locking device to the first hinge, the first hinge to couple to a low-voltage power source to supply low-voltage electrical current to the electromechanical locking device via the first electrical wire. A second wire is embedded in the hinged object that couples the electromechanical locking device to the second hinge, the second hinge to couple to the low-voltage power supply to return low-voltage electrical current from the electromechanical locking device to the low-voltage power supply via the second electrical wire.

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.

An electronic door lock is operable to control access to an access controlled area adjacent the inner side of a door. The door lock includes an outer base, an inner base, a locking mechanism movable between a locked and unlocked position in response to a control signal, and a control circuit disposed within the inner base and operable to generate the control signal in response to the presentation of an input credential. A plurality of different types of credential readers are each selectively attachable and removable from an attachment interface when the outer base is attached to the door to electrically connect the selected one of the plurality of different types of credential readers to the control circuit. The selected credential reader receives data from a user or credential and generates the input credential. A communication module is operable to communicate with a device separate from the electronic door lock.

A cabinet lock for protecting merchandise within a merchandise display cabinet having an inner door and an outer door. The cabinet lock includes a strike plate affixed to the inner door and a lock housing affixed to the outer door such that the cabinet is in a locked configuration that prevents access to the merchandise when the lock housing is operably engaged to the strike plate. A programmable electronic key communicates a security code with the cabinet lock and transfers electrical power to the cabinet lock to operate a lock mechanism between the locked configuration and an unlocked configuration. An indicator is provided for indicating whether the cabinet lock is in the locked configuration or the unlocked configuration. The indicator includes a first segment and a second segment that can be energized to visually indicate the status of the cabinet lock.
