Abstract:
1. An electronic combination lock for keyed and keyless access, comprising: a door handle having a turn button and a code entry button formed thereon, the code entry button capable of receiving an input code of sequential digits in the form of groups of momentary taps of the code entry button, each group of momentary taps of the code entry button being associated with a digit of the input code and groups of momentary taps forming the sequential digits of the input code, the door handle housing a lock assembly and an electrical circuit; the lock assembly comprising: wherein the electrical circuit receives a first input signal from a number switch being actuated by the code entry button and a second input signal from the program switch, the electrical circuit being operative to store an entry code when the program switch is actuated and to activate the magnetic coil when an input code matching the stored entry code is received for providing keyless access, wherein when the input code entered through the code entry button matches the stored entry code, the magnetic coil is activated to pull on the latch to release the lift comb, the lift comb lifting the one or more spring loaded lift lock pins out of the cylinder to allow the cylinder to be rotated within the axial opening using only the turn button, thereby providing keyless access.
