How Do Warded Locks Work?

A warded lock is a design that works on the principle of obstructions (known as wards) on or within the keyway to stop the wrong key from entering and rotating the locks. Warded locks don't have any other active components besides a spring or lever, which activate the locking bolt when the right key is used.

Are warded locks secure?

Warded locks are considered low-security by modern standards because they provide no security against lockpicking or impressioning attacks. Because modern applications of warded locks are low-security padlocks they are also commonly susceptible to bypass and destructive entry.

What is the purpose of a warded lock?

A warded lock (also called a ward lock) is a type of lock that uses a set of obstructions, or wards, to prevent the lock from opening unless the correct key is inserted. The correct key has notches or slots corresponding to the obstructions in the lock, allowing it to rotate freely inside the lock.
