When a lock should be replaced
Repair has its place, but these are the situations where a new lock is the right call:
- Key lost or stolen — the old key may still open the door
- Moving into a new home — previous occupants may hold keys
- Lock damaged or tampered with, including after a break-in
- Mechanism worn — key sticks, turns loosely or needs force
- Upgrading security to British Standard or anti-snap
British Standard locks and anti-snap cylinders
BS3621 is the British Standard for thief-resistant locks on external doors, and many home insurers ask for it as a policy condition. We fit BS3621-rated mortice locks on wooden doors, and anti-snap euro cylinders where the door uses a cylinder.
Anti-snap cylinders are designed to resist lock snapping — the attack where the exposed part of a standard cylinder is broken off to force entry. They break away safely at engineered points while the locking mechanism stays protected. Ask on the call and we will recommend the right option for your door.

A lock replacement is straightforward when it is done properly. The old lock is assessed and measured, the replacement is matched to the door and to your security needs, and the quote is confirmed before work starts — then the new lock is fitted, tested and handed over with its keys.

Frequently asked questions
What is a British Standard lock?
BS3621 is the British Standard for thief-resistant locks fitted to external doors. Many home insurers ask for it as a policy condition. We fit BS3621-rated mortice locks and can advise whether your current locks meet the standard.
What is an anti-snap cylinder?
An anti-snap cylinder is a euro cylinder designed to resist lock snapping, where the exposed part of a standard cylinder is broken off to force entry. Anti-snap cylinders have engineered weak points that break away safely while the locking mechanism stays protected.
How do I know if my lock needs repair or replacement?
A key that sticks, a handle that needs force, or a bolt that does not throw fully can sometimes be repaired. If the mechanism is worn, the lock is damaged, or the keys are lost or stolen, replacement is the safer option. We will assess the lock on arrival and give an honest recommendation before quoting.
Will a new lock fit my existing door?
In most cases, yes. Replacement locks are measured and matched to the door, the existing cut-outs and the backset. Where a door needs minor adjustment for the new lock, that work is included in the visit.
Do new locks come with keys?
Yes. Every replacement lock is supplied with its keys, and extra copies can be cut during the same visit for family members, tenants or staff.
I have just moved into a flat in Brixton. Should I change the locks?
It is strongly recommended. Previous tenants, tradespeople or estate agents may still hold keys. A lock change on moving day is quick, and it means you know exactly who has a key to your new home. Call 07984 547185 to arrange it.
