Step-by-Step Programming Instructions:

1. Locate the Data Link Port beneath the dashboard on the driver’s side. Identify pins 8 and 4 (the port is wider at the top). Note that your OBDII port may not have numbers, so refer to the provided diagram.

2. Ensure there are metal contact pins in terminals 8 and 4. Connect terminal 8 to terminal 4 using a suitable jumper wire (keep the jumper wire connected throughout the programming process). Be certain of which terminals are 8 and 4. The vehicle will respond by locking and unlocking the doors to indicate entry into programming mode.

3. Press and hold both the LOCK and UNLOCK buttons simultaneously on the first transmitter to be programmed. After approximately 15 seconds, the vehicle will respond by locking and unlocking the doors. Release the buttons on the transmitter.

4. Within one minute, repeat the previous step for the remaining transmitters to be programmed.

5. Remove the jumper wire from the OBDII Port.
