Abstract:
An electronic combination lock includes a door handle having a code entry button and housing a lock assembly and an electrical circuit. The lock assembly includes a lock body, a rotating cylinder, spring loaded lift lock pins and corresponding key pins, a reset cam path and a programming cam path formed on the cylinder, a lift comb for lifting the lift lock pins, a latch for latching the lift comb and a magnet being selectively activated to cause the latch to release the lift comb. The electrical circuit receives a first input signal indicative of an input code entered at the code entry button and a second input signal from a program switch actuated by the programming cam path and is operated to store an entry code when the program switch is actuated and to activate the magnet when an input code matching the stored entry code is received.
