Step-by-Step Programming Instructions:

These programming procedures are only applicable for vehicles built in the USA. If you don’t have any working keys and need to program a new one yourself, follow these steps:

1. After having the new key cut by a locksmith, insert it into the ignition cylinder and turn it to the ON position (without cranking the engine). The security light on the dash will illuminate and stay on for ten minutes. Once it goes out, you have one minute to proceed to the next step.
2. Turn the ignition cylinder to OFF and then back to the ON position. The security light on the dash will illuminate and stay on for another ten minutes. Once it goes out, you have one minute to proceed.
3. Repeat step 2 by turning the ignition cylinder OFF and then back to the ON position. The security light will stay on for another ten minutes.
4. After the security light has turned off for the third time, turn the key off and remove it from the ignition. The key is now programmed, and all other keys have been erased.
5. Insert the key and start the vehicle to test it.

If you want to program a duplicate key, follow these steps:

1. Insert an existing programmed working key into the ignition cylinder.
2. Turn the ignition to the ON position and then back to OFF.
3. Remove the existing key and within 10 seconds, insert the new key and turn it to the ON position.
4. The security light will illuminate for 2 seconds to indicate successful programming of the additional key. Remove the key from the ignition.
5. Insert the key and start the vehicle to test it.
