Remote keyless entry transmitter

The Remote Keyless Entry (RKE) system transmitter is equipped with three buttons, labeled Lock, Unlock, and Panic. It is also equipped with a key ring and is designed to serve as a key fob. The operating range of the transmitter radio signal is up to 7 meters (23 feet) from the RKE receiver.

Each transmitter has a different vehicle access code, which must be programmed into the memory of the RKE receiver in the vehicle in order to operate the RKE system. See Remote Keyless Entry Transmitter Programming in the Service Procedures section this group for more information.

The transmitter operates on two Duracell DL2016, Panasonic CR2016 (or equivalent) batteries. Typical battery life is from one to two years. The RKE transmitter cannot be repaired and, if faulty or damaged, it must be replaced.

Remote keyless entry receiver

The Remote Keyless Entry (RKE) receiver is a radio frequency unit that is integral to the high-line version of the Central Timer Module (CTM). The CTM also contains the program logic and control circuitry for the RKE system. The CTM is mounted under the passenger side end of the instrument panel, outboard of the instrument panel glove box opening.

The RKE receiver has a memory function to retain the vehicle access codes of up to four RKE transmitters.

The receiver is designed to retain the transmitter codes in memory, even if the battery is disconnected.

The RKE receiver is energized by one of three radio frequency inputs from the RKE transmitter; Unlock, Lock, or Panic. The programming of the CTM responds to these RKE inputs, as well as many other inputs, by sending the proper control outputs to the power lock motors, the courtesy lamp circuit, the driver unlock relay, the horn relay, and the headlamp relay.

For diagnosis or programming of the RKE receiver within the high-line CTM, a DRB scan tool and the proper Diagnostic Procedures manual are recommended.

The RKE receiver is only serviced as a unit with the high-line CTM and, if faulty or damaged, the CTM unit must be replaced.
