    The link to this site is working I hope now.


    1. Close all vehicle doors.

    2. Insert the key into the ignition.

    3. Hold down the power UNLOCK button on the driver’s door panel-continue to hold down until instructed
    to release in step 9.

    4. Perform steps 5 through 8 in fairly rapid succession.

    5. Turn the ignition switch to the ON position (as far as you can go without starting the engine).

    6. Turn the ignition switch to the OFF position.

    7. Turn the ignition switch to the ON position.

    8. Turn the ignition switch to the OFF position.

    9. Release the power unlock button on the door panel. The vehicle will lock and unlock the doors automatically.

    10. Hold down the LOCK and UNLOCK buttons on the transmitter simultaneously until the door locks and unlocks.
    This step may take up to 30 seconds.

    11. Repeat step 10 NOW for each additional transmitter (including any existing transmitters).

    12. Turn the ignition switch to the ON position in order to exit the transmitter programming mode.
