Keyless Entry Transmitter: Description and Operation

PKE Transmitter:






The transmitter unit is a battery powered, water resistant, radio frequency signal generator. Two transmitters are provided with each vehicle and each is uniquely recognized by the receiver module. The receiver module is capable of recognizing only two transmitters, therefore only two transmitters may be used with any one vehicle. Replacement transmitters for the vehicle may be obtained, however the receiver module must be programmed to accept the new transmitter.

This system allows one transmitter to be matched to as many different factory equipped RKE vehicles as the owner chooses. Each car, however, can only have two transmitters matched to it. To program several cars to one transmitter, follow the reprogramming procedure for each of the vehicles using the desired same transmitter. (Note: If two cars are matched to one transmitter, care should be taken when cars are parked near each other).
