Abstract
A keyless locking mechanism is activated by a remote unit which transmits coded signals to an electromechanical door lock device. The electromechanical device components are configured for secure mounting within the void or hollow portions of existing door locking apparatus. A sensor in the outer doorknob receives and forwards the coded signals to a processor which compares them with a predetermined stored signal. If an acceptable comparison is made, the processor generates control signals for the device, which acts solely along the locking axis to enable or disable the door locking assembly. The coded signals include 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.
