Step-by-Step Programming Instructions:

These programming procedures are solely applicable to vehicles manufactured in the USA. If you lack any working keys and aim to program a new one yourself, follow these steps:

1. Upon receiving the new key from the locksmith, insert it into the ignition cylinder and turn it to the ON position (without starting the engine). The security light on the dashboard will illuminate and remain on for ten minutes. Once the security light extinguishes, you have one minute to initiate the next step.
2. Turn the ignition cylinder to OFF and then back to the ON position. The security light on the dashboard will illuminate and remain on for another ten minutes. Once it turns off, 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 remain on for another ten minutes.
4. After the security light has extinguished 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 its functionality.

Should you wish to program a duplicate key, adhere to the subsequent 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 signify successful programming of the additional key. Remove the key from the ignition.
5. Insert the key and start the vehicle to verify its effectiveness.
