Abstract

A system and method for controlling functions of a vehicle includes first and second electromagnetic communication devices. The first electromagnetic communication device is adapted to transmit a coded response signal. The second electromagnetic communication device is adapted to receive the coded response signal. The second electromagnetic communication device is further adapted to transmit an uncoded outgoing signal and to receive an uncoded incoming signal that is a reflection of the outgoing signal.
