Remote Control Door Lock Receiver

The remote control door lock receiver is located under the left side of the instrument panel. The receiver performs the functions of interpreting the signals from the transmitter and relaying the information to the multifunction alarm. The receiver does not directly control any functions but is a interpreter for the transmitter to tell the multifunction alarm what is requested. The receiver is able to receive signals from up to four transmitters, and must be programmed to accept signals from any transmitters that are to be added or replaced.

Transmitter

The transmitter unit is a battery powered, water resistant, radio frequency signal generator. Two transmitters are provided with each vehicle. The receiver is capable of recognizing up to four transmitters. Replacement transmitters for the vehicle may be obtained, however the receiver must be reprogrammed to accept the new transmitter.
