Garage doors are a particularly weak point, since most of them have rather flimsy construction. If you have a security system, be sure it covers the garage door (you’d be surprised how many people forget this step). If you have an automatic garage door opener, you can reprogram it to have a different code than the factory setting. Contact the manufacturer for details—it’s usually very simple, and adds an extra layer of security. If you’re going out of town (or want to be extra secure overnight, or when home alone), you should consider installing a slide-bar latch or a padlock to keep the door from being manually rolled up. You can also cut a piece of wood to fit snugly into the door’s track, and clamp it in place, preventing it from rolling up. Disable the opener beforehand, so that if you forget and try to open it, you won’t damage the door.
