<p>To answer the OP, I always lock the door to the attached garage before I go to bed, and I make sure the other 4 doors are locked also. During the day the inside door to the garage is not locked. Here is a secret: We have a key to the house hidden inside the garage. Our garage is such a mess with wall to wall plastic shelves covered with junk I challenge a burglar to find that key. We also have a key to our next door neighbor’s house, and their kids occasionally come over for the key when they get locked out. We always make sure they give it back. </p>
