A remote convenience system (10) for remote control performance of a function includes a portable transceiver (14) and a controller transceiver (16). Preferably, the system (10) is for a vehicle (12), and the controller transceiver (16) is vehicle-based. The portable transceiver (14) is operable for remote control requests, and includes circuitry (42, 52, 54, and 60) for transmitting a function request signal (18) that contains a function request (C) and a security key (T.sub.1). Also, circuitry (42, 52, 54, and 60) of the portable transceiver (14) receives a response signal (36) that contains a new security key (T.sub.2), and updates to the new security key. The vehicle-based transceiver (16) includes circuitry (30, 74, 78, and 82) for processing valid function requests and for controlling performance of the requested function. The circuitry (30, 74, 78, and 82) of the vehicle-based transceiver (16) receives the function request signal (18), and transmits the response signal (36), with the new security key, to the portable transceiver (14) in response to receiving the function request signal.
