Step-by-Step Programming Instructions:

1. Insert the key into the ignition and leave it in the OFF position.
2. Find the Data Link Port beneath the driver’s side dashboard. Identify pins 8 and 4 (the port is wider at the top). Note: Your OBDII port won’t have numbers, so refer to the provided diagram for guidance.
3. Ensure there are metal contact pins in terminals 8 and 4. Connect terminal 8 to terminal 4 using a suitable jumper wire (keep it connected throughout the programming process). Confirm which terminals are 8 and 4. The vehicle will respond by locking and unlocking the doors to indicate entry into programming mode.
4. Close all doors.
5. Turn the ignition to the ON position (without starting the engine). The doors will lock.
6. Press and hold both the LOCK and UNLOCK buttons simultaneously on the first remote to be programmed. After about 15 seconds, the vehicle will respond by locking and unlocking the doors. Release the buttons on the remote.
7. Within one minute, repeat the previous step for the remaining remotes to be programmed.
8. Remove the jumper wire from the OBDII Port.
