The system includes a vehicle transceiver (C) adapted to be mounted on a vehicle for transmitting an interrogation signal and also for receiving a coded reply signal and responding thereto for causing performance of a vehicle device function. The system also includes a plurality of portable remote transceivers (A), each of which receives an interrogation signal and responds thereto by transmitting a coded reply signal. The coded reply signals from different portable transceivers have different phase delays.</p> |
