The process of programming a HomeLink system is simple if you follow these easy steps:
The HomeLink unit in your Chevy has 3 buttons on it. Usually, you’ll find these buttons on a vehicle visor or in the front center map light cluster on the ceiling. Find the first and third (outer) buttons, and press them for about 20 seconds or until the interior lights of your Chevy start flashing. Note that this is referred to as a “master reset” and will only need to be completed your first time programming HomeLink.
After you notice your ceiling lights flashing, press and hold the button you’d like to program while also holding the open/close button on your garage door opener. The lights should then change from a slow to quick flashing pattern, indicating that the programming process has finished.
Go into your garage and press the “learn” button on your garage door opener.
Return to your Chevy. Next, press the button you’ve programmed for a minimum of two seconds. You may see the lights on your garage door opener flash, indicating that it is connecting.
