Sit in your vehicle with all doors closed. Insert the key into the ignition and turn it from OFF to RUN eight times. Do this within 10 seconds. The locks will cycle to confirm programming mode. Press any button on the key fob. The locks will cycle again to confirm programming. Turn the ignition OFF. Test the key fob to ensure it is working. If the problem persists, it may need professional attention.
