Keyless Entry Transmitter: Description and Operation

SYSTEM OPERATION
The Remote Keyless Entry (RKE) system transmitter is equipped with up to three buttons, labeled Lock, Unlock, and an optional Panic button. 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. In addition, vehicles with the optional memory system must have their access codes programmed in the RKE receiver so that the molded-in numbers "1" or "2" on the back of the transmitter case coincide with the memory "1" and "2" buttons of the memory set switch in the vehicle.

Transmitter programming must be performed with a DRB scan tool. Refer to the proper Computers and Control Systems/Body Control Module/Testing and Inspection Procedures for the transmitter programming procedure.

The transmitter operates on two Duracell DL2O16 (or equivalent) batteries. Typical battery life is from one to two years. The transmitter cannot be repaired and, if faulty or damaged, it must be replaced.
