Ah, the feeling of pulling into your driveway and getting ready to walk into your warm, cozy home. It’s been a long day at work—made to feel even longer by the fact that the sun seems to set after lunchtime these days. You reach up to your sun visor to press the button on your garage door opener and… nothing. You push it again and again, even getting out of your car in the cold to hold it nearer the door. What in the world? You know that there’s nothing wrong with your remote since you just checked it a few days ago. The situation is even worse than a broken remote. You have to reprogram your LiftMaster Chamberlain opener system! Shoot.
