The power to your garage is out with the door shut, and you need to get your car out or you'll have to take a bus. You'll notice a cord—usually with a red handle—dangling down from the guide track that the opener uses to open and close the door. This is the manual override. Once pulled, it allows you to open and close the door with your own power in the form a little elbow grease.
Furthermore, newer doors come with more improved security features, helping to improve the way you protect your home and loved ones. While older doors are easy to break into, whether through breaking the lift mechanism or even using a universal garage door remote, new doors come with many redundant security features, which will go a long way in deterring even the most ingenious burglar.
