REMOTE KEYLESS ENTRY TRANSMITTER PROGRAMMING
NOTE:
- A maximum of 4 remote keyless entry (RKE) transmitters can be programmed to the vehicle. Programming must be done at the same time for all the RKE transmitters.
- Programming (or reprogramming) of the RKE transmitters can be accomplished using a scan tool or by carrying out the following steps.
1. Electronically unlock the door locks using the door lock control switch.
2. Turn the ignition switch from the OFF to the RUN position 8 times in rapid succession (within 10 seconds), with the eighth turn ending in RUN. If the module successfully enters program mode, it locks and then unlocks all the doors.
3. NOTE: If no action is taken within 20 seconds after a transmitter has been programmed, the programming sequence ends (the doors lock and unlock to confirm that programming is complete).
Within 20 seconds, press any button on the RKE transmitter to be programmed. The doors lock and then unlock to confirm that each RKE transmitter is programmed. Repeat this step for each RKE transmitter.
4. Exiting the programming mode is accomplished if one of the following occurs:
- The key transitions to the OFF position.
- 20 seconds have passed since entering programming mode or since the last RKE transmitter was programmed.
- The maximum number (4) of RKE transmitters have been programmed.
5. Check the operation of the transmitter. If the door locks do not respond for the programmed RKE transmitter(s), wait several seconds and press the button again. If the door locks still fail to respond, refer to Locks, Latches and Entry Systems. (Make sure that no more than the maximum number (4) of RKE transmitters are attempted to be programmed.)
