What is a deadbolt?

1. A lock that can be opened with a card

2. A bolt requiring deliberate action to extend

3. A type of keyless lock

4. A lock that automatically engages when closing

The correct answer is: A bolt requiring deliberate action to extend

A deadbolt is specifically defined as a type of lock that requires deliberate action to extend or retract its bolt. This characteristic distinguishes it from other types of locks, such as spring bolts or latch locks, which can spring back into place automatically when the door closes. Deadbolts are designed to provide an enhanced level of security because they cannot be easily manipulated or forced open. An individual must turn the key or use a thumb turn to secure or release the deadbolt. This level of precision in operation is what makes deadbolts a preferred choice in residential and commercial security. The other options describe different types of locking mechanisms or features that do not align with the fundamental characteristics of a deadbolt lock. For instance, a lock that can be opened with a card refers to card access systems, which are unrelated to the traditional deadbolt mechanism. A type of keyless lock generally refers to locks that do not use a traditional key but rather other forms of authentication, such as codes or biometrics, which is again different from the action required for a deadbolt. Lastly, a lock that automatically engages when closing typically refers to a spring latch mechanism, which does not provide the same level of security as a deadbolt.
