What is meant by the term "DeadLocking"?

A feature that unlocks doors automatically
Resistance against movement of the latch
A key type used in basic locks
The method of securing keys

The correct answer is: Resistance against movement of the latch

Deadlocking refers to the mechanism in a locksmithing context where a latch or bolt is secured in a manner that prevents it from being retracted by any force external to the lock, such as the manipulation through the door cylinder or a potential intruder’s tools. When a lock is deadlocked, it signifies that the latch cannot be easily moved open without the correct key or mechanism to disengage it. This feature is critical in providing additional security to doors, as it ensures that even if the latch is exposed or accessible, it will not yield to force. This distinguishes deadlocking from other locking mechanisms that may be more easily manipulated or forced open. In contrast to other options, such as automatic unlocking or key types, deadlocking specifically addresses the concept of defensive security that protects against unauthorized access.
