What Are Mortice Locks?
Mortice locks are installed within a pocket (mortice) cut into the door, making them incredibly secure as they cannot be easily tampered with or removed. Unlike surface-mounted locks, mortice locks are embedded deep within the door structure, with only the cylinder and handle visible from the outside. This design provides exceptional security and durability.
The most secure mortice locks feature 5 levers that must be precisely aligned for the lock to open, making them extremely difficult to pick or bypass. Many mortice locks also meet BS3621 standards, which means they’re approved by insurance companies and provide the level of security required for home insurance policies.

Mortice Lock Questions & Answers
A mortice deadlock has only a deadbolt mechanism and is opened/closed with a key from both sides – ideal for maximum security where you don’t need handle operation. A mortice sash lock combines a deadlock with a latch mechanism, allowing handle operation for convenience while maintaining the security of a deadlock when locked.
Most home insurance policies require BS3621 approved locks on external doors. These locks meet British Security Standards and provide the level of security insurance companies require. Installing BS3621 locks can also help reduce insurance premiums and ensure claims aren’t rejected due to inadequate security.
Mortice locks require sufficient door thickness (typically 44mm minimum) and appropriate material strength. Most wooden doors are suitable, but very thin doors or some composite doors may not accommodate mortice locks. We assess each door individually to ensure proper installation is possible.
Quality mortice locks can last 20-30 years or more with proper installation and occasional maintenance. Their robust construction and concealed position protect them from weather and tampering. Regular lubrication and professional servicing can extend their lifespan even further.
We can cut replacement keys for most mortice locks if you have the lock code or a spare key. If you’re completely locked out, we can pick most mortice locks non-destructively. In extreme cases, we may need to drill the lock, but we’ll always attempt non-destructive entry first.
Yes, mortice locks are excellent for period properties as they’re concealed within the door and don’t alter the external appearance. We have extensive experience with Victorian and Edwardian properties and use appropriate techniques to preserve the door’s integrity while upgrading security to modern standards.
