A built in garage door opener is one of those unnecessary things that after a while you realize is more of a hassle than a convenience. My wife's Suv came with one of those and it was a real pain when I was doing something in the garage and I had to leave her truck outside. I ended up deleting the code off of it and just buying a regular opener for the fear of leaving her truck outside. If you don't get my point yet, if you leave the car outside anyone come brake your car window, open your garage and in our case be inside the house. Just a thought.
