uPVC Door Lock Repair and Replacement in West Sussex
Door lock playing up? Call Geoff on 07889325487


uPVC doors are on most homes these days, and when the lock starts playing up it can be both frustrating and worrying. Maybe the handle has gone stiff, the key won’t turn, or the door won’t lock at all. Whatever the problem, Geoff at GRN Locksmith can repair or replace your uPVC door lock and get your door working properly again.
Geoff covers all of West Sussex and into Hampshire, with no call-out fee and a clear price agreed before any work starts.
uPVC doors use a multipoint locking system, the mechanism that fires several bolts and/or hooks/rollers into the frame keeps when you lift the handle. There’s a lot going on inside the door, so there are a few things that commonly go wrong:
Some of these are simple repairs. Others mean the mechanism or cylinder needs replacing. Geoff will always tell you which it is before doing the work, so there are no surprises.
Not every uPVC lock problem means a full replacement. Often a mechanism can be adjusted, realigned, or a single part swapped out, which saves you money. Sometimes the whole multipoint system has failed and needs replacing.
Geoff’s approach is simple. He’ll diagnose the actual problem, explain what’s needed in plain English, and give you an honest price. If a repair will do the job, he’ll repair it. If a replacement is the sensible option, he’ll tell you why.
As a rough guide, a new cylinder for a uPVC door starts from £85, and a new multipoint locking system starts from £200. The final price depends on the type of lock your door needs, and Geoff will confirm it with you before starting.
If your uPVC door was fitted more than a few years ago, it may have a standard euro cylinder that’s vulnerable to lock snapping. This is a quick and quiet break-in method that targets older cylinders, and it’s become one of the more common ways burglars get into homes with uPVC and composite doors.
The good news is that it’s easily fixed. An anti-snap cylinder or snap safe cylinder, rated to the TS007 1 or 3-star or Sold Secure Diamond standard, is designed to resist snapping and is what most home insurers now look for. If Geoff is replacing your cylinder anyway, it makes sense to upgrade to an anti-snap one at the same time. He’ll talk you through the options without any hard sell.
Geoff will take a proper look at the door and lock before doing anything. uPVC mechanisms can be fiddly, and the cause isn’t always obvious, so he’ll find out what’s actually wrong rather than just guessing.
Once he knows what’s needed, he’ll explain it and confirm the price. He carries a wide range of cylinders and common mechanism parts in the van, so in most cases he can sort the problem on the same visit. Before he leaves, he’ll check the door locks and unlocks smoothly and that you’re happy with how it feels.

Usually, yes. This is often a sign the door has dropped slightly or the mechanism is wearing. Geoff can frequently adjust or realign it without a full replacement. Best to sort it early, before the mechanism fails completely and locks you out.
In many cases just the cylinder, which is the cheaper fix. If the multipoint mechanism itself has failed, that’s a separate job. Geoff will tell you which you need and won’t replace more than necessary.
If your current cylinder is an older standard one, an anti-snap upgrade is well worth it for the security and is often what insurers expect. Geoff can advise based on what’s on your door now.
A new uPVC cylinder starts from £85 and a new multipoint system from £200. The exact price depends on your door, and Geoff will confirm it before any work starts. There’s no call-out fee.
Yes. Geoff can extract a broken key and sort out a replacement cylinder if needed. It’s a common job and usually straightforward.
