Claim 0:
1. A combination lock with electronic override, comprising:
a knob rotatable between a first knob position in which the combination lock is in a closed position and a second knob position in which the combination lock is in an open position;
a drive shaft selectively couplable to the knob, wherein when the drive shaft is operatively coupled to the knob, the combination lock is in an unlocked position, and when the drive shaft is not operatively coupled to the knob, the combination lock is in a locked position;
a coupler disposed between the knob and the drive shaft and shiftable between at least two positions, wherein in a first coupler position, the knob is not operatively coupled to the drive shaft, and in a second coupler position the knob is operatively coupled to the drive shaft, least in part by the coupler,
a circuit board including a processor;
a port in communication with the processor and configured to receive an access code;
an actuator in communication with the processor, the actuator operatively coupled to the coupler, wherein upon receipt of the access code by the port, the processor is configured to instruct the actuator to shift the coupler from the first coupler position to the second coupler position; and
one or more rotatable selectors each having multiple indicia disposed thereon, the one or more rotatable selectors operatively coupled to the coupler;
wherein rotation of the one or more rotatable selectors to predetermined indicium is configured to selectively place the combination lock in the locked position and the unlocked position; and
wherein when the combination lock is in the unlocked position, rotation of the knob causes rotation of the drive shaft to selectively place the combination lock in the closed position and the open position.
