Press that button THEN you can climb off your step stool, sit in your car, and press your homelink button in that you just programed. It should pick up the signal and work just fine.
Have had to do this 3 times on my car for 3 different openers.
Should work perfect after that!
this is the step that you only have so much time to do lol
i followed that and it worked on my bonneville, escalade, toyota sienna and the avalance before i sold it
