Do I need a lock on my garage door?

Whether or not you need a lock on the garage door depends on the type of garage door opener you have installed. A lock is not necessary if you have an electric garage door opener, as it would be nearly impossible for a criminal to manually open the door. Some older openers, though, still allow the door to be lifted from the outside. If you have this kind of opener, then a lock should be installed to help you maintain garage door security.
