There is described a self-powered lock system for a movable member coupled to a lock mechanism having a first state in which the movable member is locked and a second state in which the movable member is unlocked. The system comprises an electrical energy storage device having an electrical charge stored therein, a control unit for controlling the lock mechanism, a trigger unit for triggering an unlocking of the lock mechanism, and a passive detection unit for detecting an activation of the trigger unit. Upon detection of the activation, a conductive path is provided between the control unit and the storage device for powering the control unit with the charge stored in the storage device. The lock mechanism is in turn unlocked by the control unit. A generator coupled to the storage device may then generate electrical energy and store the generated energy in the storage device for future use.

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.

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.
