Zusammenfassung:A high security lock (10) includes a lock bolt (54) movable between extended and retracted positions, a bolt retraction gear (68) coupled to the lock bolt (54), and a manually-driven gear train (78, 80). When a controller verifies that user-input information is correct for unlocking the lock (10), the bolt retraction gear (68) and manually-driven gear train (78, 80) are operatively coupled such that the gear train (78, 80) can drive the lock bolt (54) from the extended position to the retracted position.
