Deadbolts should be used instead on all exterior doors. The minimum length of the throw should be 1 in. or 2.5 cm, and the surrounding collar of the deadbolt should be made of good quality material or have a freely rotating slip ring. A strike plate, which is the flat metal plate on the door frame that receives the locks throw or bolt, should be minimum 6-8 inches and installed with long screws that pass through the door frame and into the wall stud.

Another type of bolt that can be used is the bolt rim lock, which has two vertically moving deadbolts that lock into a frame-mounted striker above and below the door. These locks are suitable for wooden frames or where there are windows on the sides of the door preventing proper installation of a deadbolt. These locks provide good to excellent security, depending on the quality, and are more resistant to crowbars.

Two more modern types of locks are the push button rim-locks and digitally coded deadbolts. A push button rim-lock features a keyless lock, opened by entering the correct combination on the numbered entry pad. Keep in mind that the security code should be changed regularly so the number pad does not wear out from overuse. Digitally coded deadbolt systems with keypad or electronic remote are more expensive, but can be fitted to existing openings. They operate in the same manner as the traditional deadbolt system, but the locking mechanism can be activated without keys using an electronic remote. These systems can be of great benefit to seniors or people with disabilities.

To further add to the already increased security offered by a good quality deadbolt lock, the addition of a steel reinforcement device to both the door and frame greatly increases strength. Such a system is cost effective and simple to install.
