An interface system to a vehicle data bus having a communication range greater than a communication range between an Original Equipment Manufacturer (OEM) transceiver and an OEM remote control device already integrated in a vehicle. The interface system comprises a remote control device, a control module transceiver and a control module. The range-extension of th e system is performed by either having receivers with higher detection sensitivity or transmitters emitting signals at higher powers, or a combination of both. The interface system has a control module that can communicate with either one o f, or both, the data bus and the function control module of the vehicle. Finall y, the interface system also permits a bi-directional communication scheme between the remote control device and the control module transceiver.
