Detailed Guide to Choosing Your Deadlock

Matching Security Level to Your Door

When selecting a standard mortice deadlock, consider the door’s location and security needs. A 3 lever mortice deadlock suits internal doors or low-risk rooms, while a 5 lever BS3621 mortice deadlock is preferred for front and back doors to meet UK insurance guidelines. Available case sizes include 64 mm (2.5") and 76 mm (3").

These locks work perfectly with standard profile escutcheons to achieve a neat keyhole finish, and pair well with a variety of door furniture styles for a coordinated look.

Frequently Asked Questions

What is a mortice deadlock?

A recessed lock that operates with a key on both sides, using a solid deadbolt for secure locking.

What’s the difference between 3 lever and 5 lever deadlocks?

3 lever is for medium security (internal doors), 5 lever is for high security (external doors, often BS3621-approved).

Do I need BS3621 for my main door?

Many insurers require it for external door compliance.

Can deadlocks be keyed alike?

Yes, so one key can open multiple deadlocks.

What finishes can I choose?

Satin chrome, polished brass, and matte black are the most popular.
