We touched on this earlier, but most garages are full of valuables: cars, expensive tools, the Tollhouse cookie ice cream sandwiches in the deep freezer. When you leave your garage unsecured, you make it easy for people to walk in and take or vandalize whatever they want. Also, if you have an attached garage, then the adjoining door is an easy entrance to your house. That puts your in-home valuables—and your family—at risk too.
