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

A deadbolt and a regular door lock differ in terms of design, functionality, and level of security they provide. A regular door lock is typically a spring latch lock that mechanically engages when the door is closed. It is operated by a key, knob, or lever, and offers basic security but can be easily manipulated by force. On the other hand, a deadbolt lock provides a higher level of security. It has a solid metal bolt that extends into the door frame, making it resistant to forced entry. Deadbolts are commonly operated with a key from the outside and a thumbturn on the inside. They are an essential addition to any home's security system, offering extra protection against burglaries and intruders.
