Keyless Entry Transmitter: Description and Operation

PROGRAMMING AN RKE TRANSMITTER
Programming a transmitter can be accomplished using either the DRBIII (R) or the MDS machine. Using the DRBIII (R) select "Theft Alarm" (even though "Vehicle Theft Security System" is not available for this vehicle) then "Miscellaneous" then "Programming RKE". Select a position (1 - 4). The locks will cycle to verify you are in programming mode. Press the unlock button on the transmitter. The locks will cycle again to verify programming has taken place. When you program to a position, that code will overwrite the code that was in that position and because you have no way of knowing if a valid code was there or not, it is recommended that whenever it is necessary to program a transmitter, all transmitters that are to be used with that vehicle should be programmed at that time. The 1999 XJ will have 2 RKE transmitter.

Synchronization (Rolling Code) Button Transmitters
The transmitter will go out of synchronization if the button is pressed more than 128 times outside of the range of the receiver In other words the transmitter will not unlock the doors. The transmitter will go out of synchronization if the batteries are removed and replaced. To synchronize the code of the particular transmitter with the receiver, press and hold the "lock" button while within the receiver range.

The Remote Keyless Entry (RKE) system transmitter is equipped with two buttons, labeled Lock and Unlock. 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 for more information.

The transmitter operates on two Panasonic CR2016 (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.
