A lock which incorporates a digital programmable microprocessing interface capable of user-programming whereby a programmed combination opens the lock. According to one embodiment of the lock, there can be as many as approximately 10.times.106 possible different combinations which may be entered by the user. The operation of the lock is driven by an electric signal derived from the combination, and that electrical signal is sent to a motor assembly inside the lock body in response to which there is a disengagement of a set of locking balls from a locking bar, which with the assistance of a springing mechanism causes the locking device to open automatically.
