Gayrage problems: homo link

[kylesdenali]

Hey guys, my 2006 denali has homo link. I just rented a 4 bedroom house with some buddies and it has a two car garage. i programmed one of the doors to my left button, the middle was previously programmed to my parents door at home, this weekend I went my parents house and the middle button no longer controls that door? Any ideas? Do I just need to reprogram the middle or right button for my parents door? Will that erase the left button?

just try reprogramming it. same kind of thing happened to our lexus, got home working, programmed the controller for the beach, came back home, didnt work.

pretty sure you'll need to program all the doors at once... I could be wrong though.

If you have already programmed a door and start with far left one to program another it deletes the others.
