Door Lock Types

- May 07, 2019-

1. Mortice locks

Mortice deadlocks are one of the most common type of locks referred to in a policy. A mortice lock requires a key to both lock and open it.

2. Nightlatches

You may know these as ‘secondary locks’. In general, they come in two forms: standard nightlatches and deadlocking nightlatches.

3. Multi-point locking systems

Multi-point locking systems are now commonly used and are found mainly on UPVC doors. A multi-point locking system has a minimum of three locking points that all lock simultaneously with the turn of a key.

4. Cylinder locks

Cylinder locks are a common type of lock found on doors. You would need to check with your home insurer whether this type of lock is acceptable as some types of cylinder locks are vulnerable to a technique known as lock snapping.

5. Sliding patio doors

Sliding patio doors may be referred to specifically in a policy as the lock requirements will slightly differ from that of a standard door. Sliding patio doors can be vulnerable as they can be lifted off their runners.

6. Key-operated security bolts

Commonly used on external doors, including French and double doors. Your policy may specify that key-operated security bolts should be fitted to the top and bottom of the door.

7. Closed shackle padlocks

Closed shackle padlocks are more difficult to attack and the design of this type of lock helps prevent bolt cutters and saws getting to the shackle, which is the most vulnerable part of a padlock.
