Lock Repair in Brixton
Brixton Locksmith repairs stiff, jammed and broken locks on homes and flats across SW2 and SW9, 24 hours a day. Many faults are fixed without a full replacement, which keeps the cost down. Call or WhatsApp 07984 547185 and describe the fault for a clear quote.
Not every faulty lock needs replacing. A stiff key, a handle that droops, a bolt that will not throw — many of these faults come from wear, dirt, or a door that has shifted in its frame, and a repair sorts them out.
We look at the lock first and tell you honestly whether a repair will last or whether a replacement is the better spend. If a repair is the right call, we do it there and then.

How do I know my lock needs repair?
The earliest sign is a key that needs a wiggle or a firm push to turn. Then comes the handle that sags, the door that needs a lift or a shove to lock, and the key that sticks halfway out of the cylinder.
None of these fix themselves. A lock that is hard to turn is a lock under strain, and strain eventually snaps a key or seizes a mechanism — usually at the worst possible moment.
Common faults we fix
Stiff euro cylinders often just need cleaning and proper lubrication — graphite, not oil, which attracts dirt. Worn pins inside the cylinder can be replaced rather than swapping the whole lock.
Multipoint mechanisms on uPVC doors fail at the gearbox, the part the handle turns. A new gearbox restores the full locking action without replacing the whole strip. Misaligned doors are another frequent cause: the keeps shift, the hooks miss, and the handle will not lift.
Mortice locks on timber doors suffer from worn levers and tired springs. A service — cleaning, adjusting and replacing worn parts — often brings an old lock back to smooth working order.
Should I repair my lock or replace it?
We weigh three things: the age of the lock, the cost of the parts, and how long the repair is likely to last. A ten-year-old cylinder with worn pins is usually better replaced. A two-year-old gearbox with one broken spring is worth repairing.
If replacement is the better choice, we say so and quote both options, so you can decide with the facts in front of you. A lock change is the honest answer when the old lock is not worth saving. We never push a new lock when a repair will do.
| Symptom | Likely fix |
|---|---|
| Key stiff or sticking | Clean, lubricate, or service the lock |
| Handle droops or sags | New spring cassette or gearbox |
| Key will not turn | Realign the door or replace the cylinder |
| Lock seized or forced | Replace the lock |
We quote both options when the choice is close, so you decide with the facts in front of you.
What a repair visit looks like
We examine the lock and the door together, because the two work as a pair. A lock that will not turn is often a door that has dropped on its hinges, and fixing the door fixes the lock.
After the repair we test the lock from inside and outside, check the door latches and bolts cleanly, and show you what was done. If the fault is likely to return, we tell you that too.
What a repair visit costs
The price turns on the fault and the parts. A clean and service costs less than a gearbox replacement, which costs less than a full lock change. The locksmith prices page explains what goes into every quote.
You get a clear quote on the phone for the visit, and we confirm the price of any part before fitting it. If you want to compare quotes, the Master Locksmiths Association lists locksmiths by area — a second quote never hurts.
Frequently asked questions
Can a stiff lock be repaired, or does it need replacing?
Most stiff locks can be repaired. The usual causes are dirt inside the cylinder, worn pins, or a door that has shifted and is putting strain on the mechanism. A clean, a service, or a small part replacement often restores smooth turning. We check the lock first and tell you honestly which option makes sense.
My key will not turn in the lock. What should I do?
Do not force it, because a forced key can snap inside the cylinder and turn a small job into a bigger one. Try lifting or pushing the door gently while you turn the key, which can ease a misaligned bolt. If it still will not turn, call us and we will come and look at it.
How much does a lock repair cost in Brixton?
It depends on the fault and the parts needed. A clean and service costs less than a gearbox replacement, which costs less than a full lock change. You get a clear quote on the phone for the visit, and we confirm the price of any parts before fitting them.
Do you repair uPVC door locks?
Yes. uPVC and composite door locks are a large part of our work in Brixton. We repair multipoint mechanisms, gearboxes, handles and cylinders, and we can realign doors that have dropped. If a part is beyond repair, we explain the replacement options and the cost before doing anything.
The handle on my door has gone floppy. Is that the lock?
Often it is the spring cassette inside the handle, or the gearbox behind it. A floppy handle usually means something has worn out rather than broken outright. We can diagnose it in one visit and usually fix it there and then with the right part.
