If you don’t already have a deadbolt lock on your front door, it’s a good idea to install one. A deadbolt is a lock that is moved by turning a knob without the use of a spring; it can only be opened by the use of a knob or a key. It’s not necessary to call a locksmith to have a deadbolt installed. You don’t even need carpentry skills. This is a project that can be taken on as a DIY with the right knowledge and tools.
