The garage door is one of those things you don’t think about very often. You go to the garage in the morning, get in the car and go. Come home, you click a button, the door opens, you enter, that’s the end of it. Everyone takes it for granted that the garage door can open and close out any problems when they hit that button on the remote. Many people even use the garage door as the main entryway for their house, using the exterior keypad to get in when coming home from work or school, or after they been working in the yard.
