1. A remote controller for a vehicle, the remote controller comprising:

  • a storage module for storing control data to be transmitted to an in-vehicle transceiver;

    a transceiver switch having a transmit mode to transmit a data signal to said in-vehicle transceiver and a receive mode to listen for an acknowledgement signal from said in-vehicle transceiver;

    a user interface having at least two translucent key switches to contact said transceiver switch and thereby activate transmission of said data signal;

    at least two light sources, each beneath a corresponding one of said at least two translucent key switches to illuminate said corresponding one of said at least two translucent key switches only when said acknowledgement signal has been received and said corresponding one of said at least two translucent key switches has been released, thereby confirming that said acknowledgement signal has been received and which one of said at least two translucent key switches was depressed; and

    control circuitry adapted to receive a command from one of said at least two translucent key switches when it is depressed, retrieve said control data from said storage module, and provide said control data to said transceiver switch for transmission of said data signal, and to cause, a corresponding one of said at least two light sources to illuminate only when said acknowledgement signal has been received and said one of said at least two translucent key switches has been released.
