Tips and Notes:

• If the door locks do not cycle after pressing the power door lock button three times in step 1, start over and ensure you follow the sequence precisely.

• Programming should be completed within a short time frame (typically within 20 seconds) for each remote to ensure successful programming.

• It's advisable to test each remote after programming to ensure all are functioning correctly.
