Keyless Entry Transmitter: Service and Repair

NOTE: Keyless entry remote transmitters have individual codes and adding a new code erases a previous code. There is no sure way to determine which code is erased.

- When the customer has purchased additional keyless entry remote transmitters, or has replaced a lost keyless entry remote transmitter, the customer MUST bring to the dealer ALL of the keyless entry remote transmitters for the vehicle.
- The dealer must then reprogram ALL of the keyless entry remote transmitters at the same time.
- The remote anti-theft personality module erases all previous keyless entry remote transmitters from memory when the key less entry remote transmitters are programmed or reprogrammed.
- The remote anti-theft personality module can store up to four keyless entry remote transmitters in memory.

To program (or reprogram) keyless entry remote transmitters into the remote anti-theft personality module, perform the these steps.

1. Make sure that the anti-theft system is not armed or triggered.
2. Turn the ignition switch from OFF to RUN five times within 10 seconds, ending in RUN.

If the remote anti-theft personality module has successfully entered program mode, it will lock and then unlock all doors.

3. Press any button on a keyless entry remote transmitter, and the doors will lock and then unlock to confirm that each keyless entry remote transmitter has been programmed.

If the door locks do not respond for any keyless entry remote transmitter, wait a few seconds and press the button again. If the door locks still fail to respond, go to Diagnosis and Testing, Pinpoint Test C. C: Doors Do Not Lock/Unlock Using Keyless Entry Remote

4. Turn ignition switch OFF (or wait up to five minutes after Step 2) to exit program mode. If a new set of keyless entry remote transmitters have been programmed (or reprogrammed), the remote anti-theft personality module will lock and unlock all doors one last time to confirm.
