While some people will be able to install a deadbolt on their own, it’s not recommended. Many manufacturers will put a template and instructions in with their deadbolts, but it usually requires a number of tools and knowledge of installing locks properly. One small mistake or wrong measurement and you will find that you likely need to get a brand new door for your home. Instead of doing it on your own, call in a residential locksmith that knows and understands the processes around installing deadbolts properly.
