Additionally, the transmitter includes a key fob unit selectively connected to the control unit and to the diagnostic unit. The arrangement is such that in a first operative disposition of the key fob unit, the key fob triggers the control unit so that a first signal of the plurality of signals is generated by the transmitter unit for reception by the receiving unit.
