Keyless Entry Transmitter: Description and Operation

SYSTEM OPERATION
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. In addition, vehicles with the memory seat/mirror/radio system must have their access codes programmed into the 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.

The transmitter operates on two Duracell DL2016 (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.
