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.

The locking mechanism of claim 3 wherein the actuator assembly further comprises an actuator that operatively engages the cam for rotating the cam between the first and second position. 5. The locking mechanism of claim 4 wherein the actuator engages the cam via a clutch mechanism. 6. The locking mechanism of claim 1 wherein the guide element is a wire guide resiliently mounted against the bolt retraction gear. 7. The locking mechanism of claim 1 further comprising a biasing device having a gear advance lever, the gear advance lever engaging the bolt retraction gear and biasing the bolt retraction gear toward the engagement position. 8. The locking mechanism of claim 7 wherein the biasing device further comprises a rotatably biased drum body, the gear advance lever projecting from the drum body toward the bolt retraction gear. 9. The locking mechanism of claim 1 wherein the lock bolt includes an indentation, the locking mechanism further comprising a detent ball resiliently mounted adjacent to the lock bolt, the detent ball configured to engage the indentation and encourage advancement of the lock bolt to the extended position. 10. The locking mechanism of claim 1 further comprising a display for visualizing the user input information and a filtering device covering at least a portion of the display, the filtering device adapted to prevent a viewing of the display from a plurality of angles. 11. The locking mechanism of claim 1 further comprising: a thermal relocker including a relocker pin, the relocker pin movable under the influence of time and temperature for engaging the lock bolt in the extended position such that the relocker pin prevents movement of the lock bolt to the retraction position. 12. The locking mechanism of claim 1 further comprising a lock casing surrounding the actuator assembly, the controller, the manually-driven gear, and the bolt retraction gear, the lock casing having a first portion and a second portion, the first and second portions permanently sealed together such that separating the first and second portion damages at least a portion of the lock casing. 13. The locking mechanism of claim 1 further comprising: a rotatable lock dial adapted to receive user information;a display for visualizing user input information; anda sensor configured to sense the rotation of the lock dial,wherein the controller converts the rotation of the lock dial into the user input information visualized on the display via an algorithm. 14. The locking mechanism of claim 1 further comprising a lock casing surrounding the actuator assembly, the controller, the manually-driven gear, and the bolt retraction gear, the lock casing at least partially formed of a substantially translucent material for showing evidence of lock tampering. 15. A locking mechanism, comprising; a lock bolt movable between extended and retracted positions;a bolt retraction gear operatively coupled to the lock bolt and movable between engagement and disengagement positions;a manually-driven gear adapted to engage the bolt retraction gear in the engagement position and drive the lock bolt between the extended and retracted positions;a rotatable lock dial adapted to receive user input information;a display for visualizing user input information;a sensor configured to sense the rotation of the lock dial; anda controller adapted to store authorization information and verify user input information, the controller operatively connected to the sensor and the display for converting the rotation of the lock dial into the user input information visualized on the display via an algorithm,wherein the bolt retraction gear moves from the disengagement position to the engagement position with the manually-driven gear when the controller verifies that the user input information matches the stored authorization information. 16. The locking mechanism of claim 15 wherein the rotatable lock dial is mechanically connected to the manually-driven gear. 17. The locking mechanism of claim 16 wherein the sensor is a rotary sensor, the locking mechanism further comprising an encoder mounted on the manually-driven gear such that the rotary sensor directly senses rotation of the manually-driven gear via the encoder. 18. The locking mechanism of claim 17 wherein the user input information visualized on the display is generally random from the rotational position of the lock dial. 19. The locking mechanism of claim 18 wherein the algorithm converts the rate of rotation of the lock dial into the user input information. 20. The locking mechanism of claim 15 further comprising a filtering device covering at least a portion of the display, the filtering device adapted to prevent a viewing of the display from a plurality of angles. 21. The locking mechanism of claim 15 further comprising: a thermal relocker including a relocker pin, the relocker pin movable under the influence of time and temperature for engaging the lock bolt in the extended position such that the relocker pin prevents movement of the lock bolt to the retraction position. 22.
