A vehicle transceiver (C) is employed in a keyless entry system for gaining entry into a vehicle and also for starting the vehicle's engine. The transceiver includes means for providing a start engine signal representative that the vehicle's engine is to be started, a brake signal (134) representative that the vehicle's brake pedal has been depressed and a seat occupied signal (132) representative that an occupant is located in the vehicle's driver seat. In response to these three signals, the transceiver transmits an interrogation signal to a remote transceiver (A) which responds with a reply signal. The reply signal from the remote transceiver includes a security code that uniquely identifies the remote transceiver from similar remote transceivers. The vehicle's transceiver stores a prestored security code representative of a remote transceiver that may validly gain entry into the vehicle. The received security code from the remote transceiver and the prestored security code are compared and if a match takes place, the engine may be started. |
