The present invention provides for a locking mechanism for use in a door and the like. A remote handheld controller transmits coded signals to an electronic door lock. A sensor/receiver receives the signals and provides the signal to a processor which compares the coded signals against a predetermined stored signal. If the received coded signal matches the predetermined signal, then the processor generates control signals to actuate an electromechanical device, which acts solely along or about the locking axis, to enable or disable the locking latch. The user is then able to turn the door handle in a normal manner. The coded signals are comprised of two separate signals which are transmitted in segments interleaved with one another. The first signal includes an entrance code, while the second signal provides information concerning the frequency over which the next segments will be transmitted. The processor uses the second signal information to tune the receiver.

[ What is claimed is:] [25.] An electronic lock apparatus, comprising:(a) a strike plate;(b) a latch cooperatively engageable with said strike plate and movable between engaged and disengaged positions;(c) mechanical locking means, operatively connected with said latch, for selectively preventing movement of said latch between said engaged and disengaged positions, said locking means requiring a primary motive force;(d) electromechanical means, operatively connected to said mechanical locking means, for providing the primary motive force to said locking means; and(e) tunable electronic control means, responsive to an encoded received signal and selectively tunable among a plurality of frequencies, for selectively energizing said electromechanical means, wherein said encoded received signal comprises a plurality of packets of access and retuning information, each of said packets being transmitted at one of the plurality of frequencies, wherein said tunable electronic control means is selectively tuned responsive to packets of retuning information, and wherein said packets of access information must be determined to be valid by said electronic control means prior to energizing said electromechanical means.
