We can help with uPVC door lock repair around the clock. If you are having an issue with your uPVC door lock, you can’t ignore it. Maybe your handle is stiff, maybe the key gets jammed, or maybe it turns – but nothing happens – or worst of all, maybe your door won’t lock…
Whatever the issue, our team handles uPVC door lock repair in Chelsea day in, day out — and we can usually fix it without needing to replace the whole thing.
We’ve seen pretty much every problem you can have with these locks — from broken gearboxes and jammed multipoint systems to doors that have dropped slightly and won’t close right. Most of the time, it just needs a good look, the right part, and a bit of know-how to sort it.
Give us a call, and we’ll sort it.

Here at Chelsea Locksmith London, we know that if you have had to call us, you have probably already had a bad day.
That is why we do not want to make your day any worse or complicate matters further for you.
We’ll tell you how it is – straight – no hidden costs – no hidden surprises
As a business, we understand the need for you, our customers, to trust us. Before we send them to your premises or home, we ensure our expert locksmiths undergo full vetting (DBS checks), are fully insured and trained, and have years (sometimes decades) of hands-on uPVC door lock repair.
We are local to you. We are highly mobile. Our expertise is second to none. Our reliable services in London will not keep you waiting around all day and night.
We handle all types of uPVC lock repairs, including:
If your handle feels loose or won’t lift properly, the multipoint locking system might just need a new part or realignment.
Our technicians apply their expertise to uncover the issue with the mechanism, finding the solution to restore efficient operation.
We can usually replace the gearbox without changing the whole locking strip or the full mechanism, which keeps the cost down.
Moreover, we work with all the main brands — Yale, ERA, Mila, Fuhr, GU, Winkhaus, and more — and we’ve got most replacement parts ready to go. In short, we have the solution and have you covered.
Whether you’ve got a composite front door or a solid back door, we guarantee we can get the crucial locking system working like new again.
Composite doors are built tough, but even the best ones can start to stick or jam after years of use.
The internal mechanisms are very similar to uPVC doors, and we repair them the same way — quickly, neatly, and without any unnecessary replacements.
We’ll always check the hinges and alignment first, as sometimes you just need to adjust them slightly to get the door locking again smoothly.
A uPVC door lock doesn’t usually fail out of nowhere. Look out for these early signs:
If you want to avoid potential future security issues, then a good way to do this is to undertake preventative maintenance. This means you address the cause of the issue before it becomes a real security issue.
Just think, that loose handle that is now a security issue, could have been rectified before you were unable to lock your sliding door.
If you call us before you need our replacement or repair services, our work is essentially an early form of security services undertaken for you.

While we are experts at replacing or repairing a variety of different locks, on sliding doors, glass doors, windows, and much more, we do not offer car door lock repair services, in London or anywhere else.
Unfortunately, if you need a car door lock repair or to gain entry to a vehicle after losing your car keys, we cannot help you.
But that’s enough about what we don’t offer, we don’t like talking about that!
We’re available 24 hours a day across Chelsea, ready to help with anything from a small adjustment to a full uPVC door lock repair.
