What is the difference between a deadbolt and a regular door lock?

A deadbolt and a regular door lock differ primarily in their design, security features, and installation methods. A regular door lock, often referred to as a knob lock or lever lock, usually consists of a locking mechanism that is integrated into the door handle itself. This type of lock typically relies on a simple spring mechanism that allows the latch to retract when the handle is turned. While convenient for everyday use, standard door locks can be relatively easy for intruders to bypass, especially if the door is not solid or well-secured. On the other hand, a deadbolt is a more robust locking mechanism that provides a higher level of security. Deadbolts do not have a spring mechanism; instead, they require a key or a thumb-turn to engage or disengage the bolt. The bolt itself extends deep into the door frame, making it more difficult for an intruder to force the door open. Deadbolts come in various types, including single-cylinder and double-cylinder models. Single-cylinder deadbolts are operated with a key from the outside and a thumb-turn from the inside, while double-cylinder deadbolts require a key on both sides, enhancing security at the cost of convenience. Both lock types can be effective when used correctly, but for optimal security, many experts recommend using a deadbolt in conjunction with a regular door lock. By doing so, homeowners can significantly enhance the overall security of their doors.
