Grand Cherokee 2WD Limited V8-4.7L (2002)
Keyless Entry Transmitter Battery: Service and Repair
STANDARD PROCEDURE - RKE TRANSMITTER BATTERIES
The Remote Keyless Entry (RKE) transmitter case snaps open and shut for battery access. To replace the RKE transmitter batteries:
1. Using a trim stick or a thin coin, gently pry at the notch in the center seam of the RKE transmitter case halves near the key ring until the two halves
unsnap.
2. Lift the back half of the transmitter case off of the RKE transmitter.
3. Remove the two batteries from the RKE transmitter.
4. Replace the two batteries with new Panasonic CR2016, or their equivalent. Be certain that the batteries are installed with their polarity correctly
oriented.
5. Align the two RKE transmitter case halves with each other, and squeeze them firmly and evenly together until they snap back into place.
NOTE: The RKE system for this model uses a rolling code security strategy. This strategy requires that synchronization be maintained between the
RKE transmitter and the RKE receiver. RKE transmitter battery removal or replacement can cause a loss of synchronization. If the RKE receiver fails
to respond to the RKE transmitter following battery removal or replacement, depress and release the RKE transmitter Unlock button repeatedly while
listening carefully for the power door locks in the vehicle to cycle. After between five and eight presses of the Unlock button, the power door locks
should cycle, indicating that re-synchronization has occurred.
