ABSTRACT:
A controller for a motor vehicle security system. The controller has a SAW device adapted to receive a signal and to generate a reply signal. A decoder is connected to the SAW device for decoding the reply signal. A comparator compares the reply signal to a previously stored value and an enabling device enables operation of the motor vehicle when the predetermined value and the decoded reply signal are successfully compared.
