Choose the Right Mortice Lock for Your Door

Selecting the correct mortice lock is essential for ensuring the right level of security and functionality for your doors. At Lockco, we supply a wide range of mortice locks and latches to suit both internal and external applications, from low-security interior rooms to high-security front entrances. Understanding the differences between lock types helps you choose the best option for your property.

Here are the most common types of mortice locks and what they’re used for:

3-Lever Mortice Locks – Ideal for internal doors where moderate security is needed. Common in residential settings.
5-Lever Mortice Locks- Offers a higher level of security, often used on external doors and compliant with BS3621 insurance standards.
Deadlocks – Provide strong, key-operated locking without a handle. These locks are suitable for extra security or secondary locking.
Sashlocks – Combine a latch and deadbolt mechanism, typically used on doors with handles for both access and security.
Tubular Latches – Non-locking latches used on internal doors, suitable where privacy is required.

Frequently Asked Questions – Mortice Locks and Latches

Which mortice lock meets typical UK insurance requirements?
A 5-lever mortice deadlock conforming to BS 3621 (look for the BSI Kitemark on the faceplate) is the usual insurer requirement for external timber doors. They provided drill, pick and saw resistance plus a hardened anti-saw bolt.
What’s the difference between 3-lever and 5-lever mortice locks?
3-lever mortice locks are suited to internal doors where high security isn’t required; 5-lever versions add more levers and security features. For external doors, insurers typically expect a 5-lever BS 3621-approved lock, not a 3-lever.
When should I choose BS 8621 or BS 10621 instead of BS 3621?
BS 8621 (keyless egress) is used where you need to exit without a key in an emergency ( such as flats), while BS 10621 is for locks that can be deadlocked from the outside only. Pick the standard that matches fire and escape needs as well as security.
Do mortice locks work with cylinder sashlocks and nightlatches?
Yes, on timber doors, many setups combine a BS 3621 5-lever deadlock with a separate nightlatch or use a cylinder sashlock. Ensure any additional cylinder/escutcheon and keeps are compatible and fitted correctly to maintain security.
