What does "deadlocking" refer to in locks?

  1. A feature that enhances decorative aspects of the lock

  2. A mechanism that resists movement under pressure when fully engaged

  3. A locking mechanism that does not require a key

  4. A way to increase the speed of unlocking

The correct answer is: A mechanism that resists movement under pressure when fully engaged

"Deadlocking" refers to a mechanism that resists movement under pressure when fully engaged. When a deadlock is activated, it typically involves a bolt that extends into the door frame, creating a scenario where the lock cannot be easily forced open. This mechanism adds an additional layer of security as it prevents manipulation from outside forces, ensuring that the lock remains securely in place, even if there is attempted unauthorized access. This term is pivotal in understanding the security features of locks, particularly in high-security situations where the integrity of the lock is paramount. Deadlocking mechanisms are commonly used in deadbolts and other locking devices where resistance to forced entry is essential, making them a standard choice for residential and commercial security systems.
