There is described a remote controller for a vehicle. A storage module stores control data to be transmitted to an in-vehicle Transceiver. A transceiver switch has a transmit mode to transmit a data signal to the in-vehicle transceiver and a receive mode to listen for an acknowledgement signal from the in-vehicle transceiver. A user interface has at least one translucent key switch to contact the transceiver switch and thereby activate transmission of the data signal. A light source is provided beneath the translucent key switch to illuminate the translucent key switch when the acknowledgement signal has been received. Control circuitry is adapted to receive a command from the translucent key switch when it is depressed, retrieve the control data from the storage module, and provide the control data to the transceiver switch for transmission as the data signal, and to cause the light source to illuminate when the acknowledgement signal has been received.
