Step by Step How to Programming Instructions:
Programming with Two Recognized Keys:
To program a new key:
1. Insert the original, already programmed key in the ignition and turn the ignition on without starting the vehicle.
2. Turn the ignition off, and remove the key.
3. Quickly, within five seconds, insert the second original already programmed key in the ignition and turn the ignition on without starting the vehicle.
4. Turn the ignition off, and remove the key.
5. Insert the new key to be programmed, and within five seconds, turn the ignition on without starting the vehicle. The security light will turn off once the key has been programmed.
6. Repeat Steps 1–5 if additional keys are to be programmed.
Programming without a Recognized Key:
Program a new key to the vehicle when a recognized key is not available. Canadian regulations require that owners see their dealer. If two currently recognized keys are not available, follow this procedure to program the first key. This procedure will take approximately 30 minutes to complete for the first key. The vehicle must be off and all of the keys you wish to program must be with you.
1. Insert the new vehicle key into the ignition.
2. Turn the ignition on without starting the vehicle. The security light will come on.
3. Wait 10 minutes until the security light turns off.
4. Turn the ignition off.
5. Repeat Steps 2–4 two more times. After the third time, turn the ignition on without starting the vehicle; the key is learned and all previously known keys will no longer work with the vehicle.
6. To program the second key, turn the ignition off and insert the second key to be learned and turn the ignition on without starting the vehicle. After the two keys are learned, remaining keys can be learned by following the procedure in
