Abstract
A unique transmitter broadcasting a single RF (radio frequency) signal in response to a single input for controlling a plurality of electrical vehicle accessories. To control the plurality of accessories, the RF signal conveys multiple information components. In a preferred embodiment, the transmitter operates in conjunction with a RF receiver installed in a vehicle to unlock the doors of the vehicle when a unique RF signal is broadcast within a defined range and actuate the horn of the vehicle when the same RF signal is broadcast outside of the defined range.
