Most people don’t think about their locks until something goes wrong. These are the times we’d always recommend a lock change.
You’ve just moved in. Previous owners, tenants, cleaners and builders may all still have keys. A lock change on day one puts you back in control of who has access to your home.
Your keys have gone missing. If your keys went missing with anything showing your address, get a lock replacement the same day. Don’t wait to see if they turn up.
After a burglary. If someone has forced entry, the lock is often damaged or snapped. See our burglary repairs below.
Between tenants. Landlords should change the locks at every tenant changeover. It protects the new tenant, and it protects your property.
The lock is worn or sticking. A key that needs forcing, a stiff turn or a wobbly lock are signs the door lock is failing. Often it’s poor door alignment putting pressure on the lock. A lock repair or replacement now is cheaper than an emergency call-out later. Loose or wobbly cylinder? Read our guide.
Your insurer needs it. Many home insurance policies ask for British Standard locks on external doors. If yours aren’t, a claim could be refused.
Wandsworth has every kind of door going: Victorian terraces with a night latch and a mortice, converted flats with fire doors, and uPVC and composite doors in the newer developments around Wandsworth Town. Our locksmiths are capable of lock replacement on every one of them.
We fit trusted brands including Ultion, ABS, Mul-T-Lock, Yale and Banham. Our vans carry a wide range of replacement locks, so most jobs are finished on the first visit with your new locks installed and tested.

Not every problem needs a new lock. If the lock itself is fine but the door has dropped or the alignment is off, a lock repair and a quick door adjustment may resolve it. Using our expertise, we’ll check the lock, the door and the frame, then tell you honestly whether repair or lock replacement is the better option.
If you need new keys because yours are lost or you’ve just moved in, a cylinder replacement is usually the quickest and most affordable fix.
Insurers often ask for locks that meet a British Standard. The markings can be confusing, so here’s what they mean in plain English.
| Marking | Found on | What it means for you |
|---|---|---|
| BS 3621 | Mortice locks and night latches | The standard many insurers ask for on wooden front and back doors. |
| TS007 3-star | Euro cylinders | Tested against snapping, picking, bumping and drilling. |
| Sold Secure SS312 Diamond | Euro cylinders | One of the highest anti-snap security ratings. |
Not sure what your policy needs? Check the security section of your home insurance documents, or read it out to us when you call, and our locksmith will check your existing locks. If your locks fall short, we’ll recommend the right lock replacement and tell you exactly what we’ve fitted.
A break in leaves more than damage. It leaves you worried about your safety in your own home. Our burglary repairs service runs 24 hours a day, and every burglary call is a priority.
When burglars gain access, they usually go for the lock: snapping the cylinder, forcing the door against the frame or splitting the keep. Our burglary repairs cover:
Snapped or damaged locks replaced with anti-snap or BS 3621 locks.
Forced entry damage repaired so the door closes and locks properly again.
If a door or window can’t be repaired straight away, we make the property secure until it can.
