Access to a motor vehicle (15) is controlled from a remote location by sending a command over the common carrier telephone system (66) from to a radio frequency transceiver (40) located in proximity to the vehicle. The radio frequency transceiver (40) may be a base station (64) for a cordless telephone or part of a cellular (72) or satellite (82) telephone system which employs the digital enhanced cordless telecommunications (DECT) standard protocol. A radio frequency communication link (43) is employed to relay the command to another radio frequency transceiver (30) located in the vehicle (15). In response to receiving the command, a control circuit (15) in the vehicle activates a device (20) that performs the function indicated by the command. <IMAGE> |
