it's a novelty lock
The 'laser' lock does work, uses 2-AAA batteries and one CR2032. It can be re-locked without remote. Batteries can be changed while locked. It has 2 backup keys which can be duplicated (standard ILCO # 997D). It is much larger, bulkier and heavier than the average combination style lock. Dimensions close to 1" x 2" x4". Unfortunately the internal locking dog is plastic which makes it too weak for any security purposes.
