A combination device that, when operated through a dial through a pre-determined combination, rotates internal Barriers and aligns a system of holes that allow an optical emitter to extend a beam of light to an optical receptor which sends a signal to a locking mechanism to disengage its lock. Also, by rotating the dial outside of the pre-determined combination, the Barriers' holes are out of alignment and thusly no signal may be sent, which sends a signal to a locking mechanism to engage its lock.
