Yale lock stiff, stuck or not latching? We repair and replace Yale locks and other night latches on front doors across Knightsbridge and central London, around the clock.
The Yale lock on the front door of your property does a lot of work. It’s opened and shut dozens of times a day, the door is slammed against it, and London’s damp winters and dry summers make timber doors swell and shrink around it. Sooner or later, the key gets stiff, the latch sticks, or the door won’t stay closed.
Knightsbridge Locksmith repairs Yale locks and other night latches for homeowners, landlords and businesses alike, as part of our full range of locksmith services. We repair the lock where we can and replace only the part that has failed. If the lock is worn out or below the security standards your insurer expects, we’ll recommend a replacement and agree the price with you first.
In London, “Yale lock” usually means any night latch: the lock fitted to the inside face of a front door, with a round cylinder on the outside and a handle and small button on the inside. Yale is the brand that made this type of lock famous, so the name stuck. Many “Yale locks” on London front doors are actually made by ERA, Union, Banham or others, and we repair all of them.
Night latches are popular for their convenience: the door locks behind you. When you close the door, the spring-loaded latch clicks into the keep on the frame and holds the door shut. From outside you open it with the key, and from inside you pull the handle. The snib button lets you hold the latch back, or lock the handle, depending on the model. Better night latches can also be deadlocked with the key, so the latch can’t be forced back when you’re out.
Yale keys operate the rim cylinder, the round part you see on the outside of the door. The cylinder is separate from the latch body, which is useful: if the key is lost, worn or no longer turns smoothly, we can often swap just that part and give you new keys, without changing the whole lock.
Most Yale lock faults have a simple cause. Here’s what we usually find, and how we fix it.
| Problem | Usual cause | How we fix it |
|---|---|---|
| Key is stiff or won’t turn | Worn cylinder pins, a worn or badly copied key, or dirt in the cylinder | Clean and service it, or fit a new rim cylinder with new keys |
| Door won’t stay closed | Latch not reaching the strike plate, often because the door has dropped or swollen | Adjust or move the strike plate and keep, and ease the door if needed |
| You have to pull or push the door to lock it | Strike plate out of line with the latch bolt | Realign the strike plate so the latch closes cleanly |
| Snib button broken or stuck | Worn or broken snib mechanism inside the latch body | Repair the latch body, or replace it if parts aren’t available |
| Latch sticks or won’t spring back | Broken internal spring or worn latch bolt | Replace the spring or the latch body |
| Key snapped in the lock | Worn key, or a key forced in a stiff cylinder | Extract the broken key, then service or change it |
| Lock loose on the door | Screws stripped in the timber, or the cylinder connecting bar has worked loose | Re-fix the lock body securely |
| Handle won’t open the door from inside | Deadlocking or snib engaged, or a broken internal mechanism | Open the door, then repair or replace the latch |

We always try to repair first. Replacing a lock that only needs a new spring or an adjusted strike plate costs you more than it should.
Our locksmith repairs the latch body itself: broken springs, a stuck or broken snib button, a worn latch bolt, or a handle that no longer pulls the latch back. Most repairs are done on the spot, with common parts carried in the van.
If the problem is the key or the cylinder, our locksmith changes only the rim cylinder. You keep the latch, get new keys, and every old key stops working. It’s the quickest fix after lost keys, too.
When the lock is old, badly worn, damaged in a break-in, or below BS3621, a full lock change is the better option for front door security. We install a new night latch, and adjust the strike plate so the new lock closes perfectly. See all lock replacements.
The strike plate is the metal plate on the door frame that the latch bolt clicks into. When a door drops on its hinges, swells in wet weather or is slammed for years, the latch stops lining up with it. The door bounces open, has to be pulled hard to close, or only locks if you lift the handle.
Strike plate problems are one of the most common reasons our locksmiths are called to a Yale lock, and one of the cheapest to fix. We adjust or reposition the strike plate and keep, check the hinges, and make sure the door closed position lines up with the latch, so the lock works without force. Forcing a misaligned latch every day also wears out the lock faster, so it’s worth fixing early.
Night latches lock automatically when the door closes, which is why so many lockouts start with a Yale lock. Keys left inside, a door that blew shut, or a snib that slipped while you were out are all common emergencies, and our locksmiths deal with these emergencies around the clock.
Our locksmiths carry the right tools to open night latches using non-destructive door opening wherever possible, so the lock and door aren’t damaged. We check that you live at the property before opening any door. If the lock was the cause, we’ll repair it before we leave. See locked out of house and locked out of flat, our emergency door opening service, or contact us on 07309 909989.
Many older Yale locks are basic night latches. They’re convenient, but they don’t meet the British Standards most UK home insurers ask for on a front door, and they offer limited resistance to forced entry.
Good front door security starts with the right lock. Whatever your security needs, our locksmiths will recommend a night latch that suits your door and meets your insurer’s security requirements.
An upgrade to British Standards helps Yale locks remain secure for years, gives better security for your home or business, and can enhance your insurance cover. We supply and install BS3621 night latches from leading UK brands. See our high-security locks service for the full range of options.
Yale also makes multipoint locks, gearboxes and euro cylinders for uPVC and composite front doors. When the handle drops, the key won’t turn, or the multipoint lock won’t engage when you lift the handle, the gearbox is usually worn or broken.
We repair Yale uPVC door locks by replacing the gearbox or the multipoint mechanism, and fit anti-snap euro cylinders to enhance security. We also adjust the door so the locking points line up and the door closes without force.
Night latches and Yale-style locks are often fitted to an internal door too, such as a home office, a bedroom in a shared house, or a staff-only room in a shop. We repair and change these locks in the same way, and can open one that’s locked without damaging the door.
Yale also makes smart locks, keypad locks and app-controlled systems. Our focus is mechanical Yale locks and night latches, but if a Yale smart lock or other smart locks have a mechanical fault, call us and we’ll tell you honestly whether we can help. For most London front doors, a well-maintained mechanical night latch is still the simplest and most reliable choice, but we’re happy to assist with Yale smart locks where we can.
Most London front doors have a night latch from one of a handful of brands. We repair and replace Yale products and all of these:
Every Yale lock repair is carried out by experienced locksmiths who work on night latches every week. Our highly trained, professional and DBS-checked locksmiths bring the tools and expertise to fix most faults on the spot. We also give honest advice on whether a repair or a new lock best suits your security needs.
Our customers range from homeowners in mansion flats to shops and offices on Brompton Road. Whether you’re a homeowner or one of our business clients, you get the same locksmith services and the same expertise.
Our professional locksmiths also advise landlords, property managers and clients with several properties on practical lock solutions, from simple repairs to upgrading the entry systems on every front door. Commercial customers get the same professional advice before any work starts.
A little maintenance keeps Yale locks working smoothly and helps protect your property between visits.
The same maintenance helps other Yale systems on your property too, from lever mortice locks to padlocks and the locks on your windows, and it will enhance their life as well. If a lever lock on the same door starts to feel stiff, call a locksmith early. For long term security on a front door, we recommend combining a BS3621 night latch with a mortice deadlock. It adds a little time when you leave, but it’s worth more than the convenience of a single latch.
The cost of a Yale lock repair depends on what has failed. Adjusting a strike plate or replacing a spring costs much less than a new rim cylinder, and a new cylinder costs less than a full BS3621 night latch.

Most Yale locks can be repaired. Broken springs, a stuck snib button and a misaligned strike plate are all repairable. If the cylinder is worn, we change just that part. We only recommend a full replacement when the lock is badly worn, damaged or below BS3621.
Usually because the cylinder pins are worn, the key is worn or badly copied, or the cylinder is dirty. Don’t force it, as the key can snap. We can service it or fit a new one with new keys.
Most often the latch no longer lines up with the strike plate, because the door has dropped or swollen. Adjusting the strike plate and keep usually fixes it quickly.
That’s the snib button. Depending on the model, it holds the latch back so the door doesn’t lock when it’s closed, or locks the inside handle. If it’s stuck or broken, the latch body can usually be repaired.
A basic night latch usually isn’t. Most home insurers ask for a BS3621 lock on the front door. We can upgrade your Yale lock to a BS3621 night latch with an anti-snap cylinder.
It depends on what has failed. We confirm the call-out charge on the phone, then agree the full price on site before any work starts. Payment is on the day, by card, cash, Apple Pay or Google Pay.
We don’t cut keys, but if your keys are lost or worn, we can fit a new rim cylinder. You get new keys straight away, and the old keys stop working.
Yes. Our locksmith services run around the clock, 24 hours a day, and our locksmiths handle emergencies at weekends and on bank holidays too.
Stiff key, sticking latch or a door that won’t stay closed, we’ll fix it, usually in one visit.
