Program my 2012 gmc garage door opener.
The light above the button you were pressing will blink repeatedly.
Continue to hold down both buttons while the universal home remote light flashes slowly then more rapidly.
Press both the hand held garage door opener button and any one of the three buttons on the universal home remote system at the same time and hold them down.
Release both buttons after the light goes out.
Go to the garage door opener receiver motor head unit and locate the learn or smart button.
Keep it held down until the garage door begins to close.
As soon as this happens release the button.
After you press this button you now have 30.
