Step-by-Step Programming Instructions:

Here’s a step-by-step guide to programming keys to your vehicle:

Programming with a Recognized Key:
1. Insert the original, already programmed key into the ignition and turn it to the ON/RUN position.
2. Turn the key to LOCK/OFF and remove it.
3. Insert the new key to be programmed and turn it to the ON/RUN position within five seconds. The security light will turn off once the key has been programmed.
4. Repeat Steps 1–3 if additional keys need to be programmed.

Programming without a Recognized Key:
If you don’t have a recognized key available, follow this procedure to program the first key:
1. Insert the new vehicle key into the ignition.
2. Turn to ON/RUN. The security light will come on.
3. Wait for 10 minutes until the security light turns off.
4. Turn the ignition to LOCK/OFF.
5. Repeat Steps 2–4 two more times. After the third time, turn to ON/RUN; the key is learned, and all previously known keys will no longer work with the vehicle. Remaining keys can be learned by following the procedure in “Programming with a Recognized Key.”
