The Ultimate Guide to Mortice Deadlocks

Why Choose a Mortice Deadlock?

Mortice deadlocks are a time-tested locking solution trusted for their reliability and security. Unlike surface-mounted locks, mortice deadlocks sit inside a recess cut into the edge of the door, making them difficult to tamper with. Operated by key from both sides, they offer superior protection — a smart choice for homeowners and businesses alike.

Frequently Asked Questions

What is a Standard Mortice Key Deadlock?

A mortice key deadlock is a lock fitted within the door rather than on the surface, featuring a deadbolt that is locked and unlocked using a key. It offers a sleek and secure solution for doors.

What is the difference between 3 Lever and 5 Lever Mortice Locks?

3 Lever locks are slimmer and usually used for internal doors. 5 Lever locks are more robust, commonly used on exterior doors, and often comply with BS3621 standards required by insurers.

How do I know if my lock is BS3621 rated?

Look for the British Standard kite mark and the words “5 Lever” on the lock faceplate. This indicates compliance with stringent anti-theft standards.

Can I install a mortice deadlock myself?

Yes, but it requires cutting a recess into your door, so we recommend using a professional installer for best results.

Do mortice deadlocks require handles?

No, Standard Mortice Key Deadlocks only use a deadbolt mechanism and don’t require a latch or handle.
