ABSTRACT:
A portable transceiver is provided for use with a remote keyless entry system for controlling the locking-unlocking functions of a motor vehicle door lock and causing performance of a vehicle function. The transceiver includes a signal receiver for, when turned on, receiving an interrogation signal and responding thereto by transmitting a coded reply signal requesting performance of a vehicle function. A power supply is carried by the portable transceiver for purposes of supplying operating power for use by the signal receiver. A timer and controller are arranged to turn-on transceiver operation for a predetermined period of time when an interrogation signal and timed power pulse are received concurrently.
