Deadbolt: meaning, definitions and examples

The term 'deadbolt' dates back to the late 16th century, deriving from the words 'dead' and 'bolt.' The 'dead' in deadbolt refers to the fact that the bolt is not moveable and does not have a spring mechanism like other types of locks. Instead, the bolt is activated by a key or thumb turn, allowing it to extend deep into the door frame when locked. This added feature provides an extra layer of security compared to traditional locks. The deadbolt became increasingly popular in the 19th century as the demand for more secure locking mechanisms rose, particularly in urban areas experiencing higher crime rates. As a result, various designs and locking systems were developed. Over time, advancements in technology have also led to the emergence of electronic and smart deadbolts, which allow for keyless entry and remote operation, reflecting ongoing innovations in home security.
