Mortice lock jobs we handle
Whether you need a new lock or an old one fixed, we cover every common mortice lock problem.
Upgrading to BS 3621
Older 2- or 3-lever mortice locks rarely meet insurance requirements. We replace them with 5-lever BS 3621 deadlocks that fit the existing door wherever possible.
Stiff or seized mortice locks
Mortice locks can seize when levers wear or the bolt catches on the keep. We service, adjust or repair the lock so the key turns smoothly.
Fitting a new mortice lock
Doors with only a night latch are much easier to force. We cut in and fit a new mortice deadlock neatly, including the keep in the frame.
Mortice deadlocks, sashlocks and lever counts explained
A mortice lock sits inside a pocket cut into the edge of a timber door, which makes it far harder to force than a surface-mounted lock. A deadlock has a single bolt operated by the key. A sashlock adds a handle-operated latch, so the door can be closed without locking it, which suits back doors.
The number of levers affects security. Five-lever locks offer many more key variations and better resistance to picking than three-lever locks, and models certified to BS 3621 add protection against drilling and forcing. That's the standard most home insurance policies refer to.
Timber doors in older East London houses are often original, so we take care to keep them intact. Where an existing cut-out fits a modern BS 3621 case, we use it; where it doesn't, we adapt it carefully rather than cutting a new pocket and weakening the door.

Mortice lock FAQs
What is a BS 3621 mortice lock?
It's a lock certified to the British Standard for thief-resistant locks, usually a 5-lever mortice deadlock. Most home insurers ask for one on timber external doors.
Can you fit a mortice lock to my existing door?
Usually, yes, as long as the door is solid timber and thick enough. We check before quoting.
My mortice key is hard to turn. Can it be fixed?
Often, yes. Stiffness usually comes from worn levers or a misaligned keep, which we can service or adjust.
What's the difference between a deadlock and a sashlock?
A deadlock has only a key-operated bolt. A sashlock also has a latch worked by a handle, which suits back doors.
Can you fit a mortice lock to a uPVC door?
uPVC doors use multipoint mechanisms instead. See our uPVC door repair service for those.
