  • High security lock
    Patent number: 8635893
    Abstract: A high security lock includes a lock bolt movable between extended and retracted positions, a bolt retraction gear coupled to the lock bolt, and a manually-driven gear. When a controller verifies that user-input information is correct for unlocking the lock, the bolt retraction gear and manually-driven gear are operatively coupled such that the gear can drive the lock bolt from the extended position to the retracted position.
