My wife and I moved into a new house in Virginia last year and almost immediately started renovating. We hadn't had time to get to know our new neighbors, and one day when I decided to change the front door, one of the neighbors saw me and thought I was a burglar. He called the cops, and I had to prove I was the house's new owner. In some states, this kind of action is considered a crime. So if you decide to do the repairs yourself, I advise you to ask which states Require a Locksmith License. Only a licensed locksmith should replace locks. I didn't know that before.
