Step-by-Step Programming Instructions:

1. Locate the Data Port.
2. Insert keys in the ignition and leave them in the OFF position.
3. Ensure there are metal contact pins in terminals 1 and 4, and connect the Data Port with a suitable jumper wire. Leave the jumper wire connected throughout the programming procedure. Make sure you know which terminals are 1 and 4.
4. Within 10 seconds after connecting the jumper wire, swiftly turn the ignition switch to the ACC position and then back to OFF. Repeat this procedure two more times very quickly (you should be able to complete the 3 ACC to OFF cycles in less than 2 seconds). Note: The doors will automatically lock and unlock once at this time, indicating that the system is in the programming mode.
5. Press the LOCK button on the remote to be registered three times within 10 seconds. Upon successful programming, the doors will lock and unlock once.
6. If there are two remotes, register the first, then register the second by repeating step 5 within one minute. After completing the second programming, the doors will lock and unlock once.
7. Disconnect the programming wire and remove the keys from the ignition.
