The garage door opener button on the rear view mirror was working wonderfully until about 3 days ago. I was actually surprised how easy it was to set up but now it no longer works. Not only that, but I can't get confirmation of deleting the codes to start over. Press the first and third buttons for 20 seconds and the light on the mirror sensor is supposed to blink. Not lights.
Thoughts? Anything else I can try? BMW insists on coming over to my house to figure it out. I guess that's not so bad. Pretty good service but I'd rather do it myself if there's something I'm just being dumb about. I have the rolling code on the garage door operator but I can't even get that far as I'm stuck in that I can't even delete current codes.
