uPVC Door Not Locking Properly?
You probably do not need a new door. J.K Locksmiths Castleford repairs and replaces uPVC and composite door locks, including failed multipoint mechanisms, worn cylinders and doors that have dropped out of alignment, and in most cases the fault is a part inside the door, not the door itself.
The symptoms we hear most: the handle lifts but the door will not lock, the handle has gone floppy, or the key turns but the door will not open. There is no call-out charge. If it is a straightforward lock repair, that is what you pay for.
What Is Your uPVC Door Actually Doing?
Think of the symptom as a diagnosis waiting to happen. A uPVC door rarely fails silently; it sticks, droops or refuses in a particular way, and that pattern usually tells us which part has given up before we get there, which in turn means a more accurate figure on the phone.
When the handle lifts but the door will not lock
The locking points may not be finding the keeps correctly. Incorrect door alignment or an internal multipoint mechanism fault can account for this. Please avoid forcing the handle repeatedly, because the door and the lock should be inspected together.
It only locks if you lift and shove
When locking takes real effort, the door has usually dropped or the frame has moved. Each forced lift adds pressure on the locking points, so the alignment deserves attention sooner rather than later.
The handle has dropped or feels floppy
A floppy handle may involve its fixings or the spindle that runs through the door. An internal gearbox fault is another possible explanation for it. We check the handle and locking mechanism as one before the right repair is decided.
The key will not turn from outside
The issue may be the key or the euro cylinder. Difficulty turning the key can also result from pressure created by incorrect door alignment or the internal mechanism. Do not force a lock that stays stiff; the cause should be confirmed before a repair or replacement is recommended.
The key turns, but the door will not open
A key that turns is not proof the complete locking system is working. The cylinder, the latch or the central gearbox may be involved. Stop if the key or handle meets strong resistance, since further force could place more strain on the mechanism.
A door locked shut that will not open at all
A cylinder or internal mechanism fault can prevent the door from opening, and poor alignment can also load the locking points. What has gone wrong and the door's condition determine how it is opened. A locksmith can inspect it and determine an approach intended to limit avoidable damage, aiming to regain access, though damage-free entry cannot be guaranteed in every situation.

uPVC Door: The Three Parts That Fail
Three systems sit behind every uPVC door handle: the cylinder, the gearbox with its multipoint strip, and the alignment of the door itself. Each fails differently, and each costs a different amount to put right.
Alignment of the door
Start here, because it is often overlooked. Alignment is separate from the lock, yet it governs how the locking points meet the keeps in the frame. When it slips, the key or handle can become difficult to operate, and an adjustment may be needed even though the lock has not fully failed. Some lock problems are caused or made worse this way, so the price reflects the cause and the adjustments required. Separate work from a door specialist may be necessary to address significant damage or structural faults in the door.
A multipoint gearbox
The gearbox is what turns a lift of the handle or a turn of the key into movement along the multipoint system. If it develops a fault, the door may not lock or unlock correctly. In some cases a replacement gearbox can go in without a new strip, though that depends on compatibility and on the condition of the remaining mechanism. The strip itself runs along the door edge and works hooks, rollers or bolts, depending on the system. It may need replacing in full if several parts are damaged or a compatible gearbox-only repair is not appropriate. A complete strip brings different parts and fitting work, so whether the gearbox can be replaced separately affects the price, as do compatibility and component availability.
Euro cylinder
The part of the lock operated by the key is the cylinder. Although it works with the gearbox, it can often be replaced on its own; in suitable cases the gearbox and full multipoint mechanism stay as they are. Correct sizing and compatibility with both the fitted lock and the protective door hardware must be ensured for any new cylinder. Its price depends on the required size and security rating.
You Almost Certainly Do Not Need a New Door
Window companies fit doors. Locksmiths fix locks. If your uPVC door has stopped locking, the fault is almost always in the hardware, whether that is a failed gearbox, a worn cylinder or a door that has dropped, and fixing it costs a fraction of what a new door would.
In some cases only one part of the system needs attention; which option suits depends on the fault, on component compatibility and on how sound the remaining mechanism is. The gearbox in the centre of the door may be the single part causing the problem, and a compatible replacement can sometimes go in without changing the full strip, depending on its model and the condition of the parts around it. If several components are worn or damaged, or the strip has failed and no suitable gearbox-only option is available, the whole strip may be replaced, and it must be compatible with the door and its locking arrangement. The door can sometimes be the cause; we can assess how its condition affects the locking, though severe warping or profile damage may need more than an adjustment or a replacement lock part, and wider structural repairs may need a suitable door specialist. Before recommending anything, we assess the complete locking operation.
Composite Doors Also
If your door is composite, the same help applies, because we cover both. Many composite doors use euro cylinders and multipoint mechanisms similar to uPVC, meaning a fault can affect the key, handle or locking points, and poor alignment can stop the mechanism from working correctly. The denser slab is harder to work on and hardware sizing varies more, so door construction and fitted hardware are assessed before a compatible repair or replacement is put forward.
Usually, You Do Not Need a Whole New Mechanism
Here is the cost insight most people never hear. A failed multipoint usually means a failed gearbox, the central unit, not a failed full-height strip, and if the strip and hooks are in good order the gearbox alone can normally be changed. That is a materially smaller job, and a smaller bill, than replacing everything.
We will tell you plainly when the whole strip does need to go: if it has been physically damaged by a forced entry, if it is corroded, or if the system is obsolete and its gearbox is no longer manufactured. More on that choice is on our lock replacement page.
While We Are There, Upgrading the Cylinder
While we are replacing a cylinder, it is worth asking whether to upgrade it. The euro cylinder is where your key goes, and it can often be changed in suitable cases without replacing the gearbox or complete multipoint mechanism. Replacement makes sense when the current cylinder is damaged or unreliable, when it is incorrectly sized, or when you would simply like to consider a recognised security-rated option. Our recommendation is an anti-snap rated cylinder, which adds little to a job already under way, but you are free to keep a standard cylinder replaced like for like.
Check the face of your cylinder today
for a star rating or a Diamond mark. Options may include TS 007 three-star and SS 312 Diamond-rated cylinders, as some replacement cylinders are certified to recognised security standards.
Remember the rating is not the whole story.
Not every rated cylinder suits every door; it has to be correctly sized for your door and compatible with the fitted lock and protective hardware.
Read your insurance policy.
Some policies specify a lock or cylinder standard, so check the exact wording, and you can ask your insurer to confirm what it requires before choosing.

How Much Does a uPVC Door Lock Repair Cost?
Four outcomes, very different costs. A cylinder swap is usually the cheapest result, a gearbox-only repair costs more, and a complete mechanism replacement costs the most, which is why there is no single fixed price for every uPVC door lock repair. The cost depends on the fault, any replacement parts and the work required, and the fix may be an adjustment, a repair or a replacement component. The repair required can also depend on how the door is aligned.
What moves the price - the failed part - gearbox only, or the complete strip - an optional cylinder upgrade - realigning the door - the time of day
Our work covers uPVC and compatible composite doors: lock and door alignment assessed, repair and replacement options explained. There is no call-out charge, and we give you a price on the call. Tell us how the key and handle behave and whether the door opens, closes and locks normally; we use your description to give you the price during that call. Inspection identifies the fault and whether it requires adjustment, repair or a compatible replacement part. That phone price stays unless the job differs on site; any change is explained before work begins, and you approve the work first. We then carry out the approved work, test the key, handle and locking, and check door alignment and locking-point engagement where relevant. You pay for the work carried out, any parts needed, and VAT, nothing on top. Rates outside Monday to Friday, 7am to 6pm, are higher, but the call-out itself is never charged, so a visit is never billed just for turning up.

Frequently Asked Questions
My uPVC door handle has dropped and will not lift. What is wrong?
Almost certainly the multipoint gearbox. When it fails internally, the handle loses its engagement and drops. The door may still be locked, because the hooks and bolts can stay engaged even though the mechanism is no longer working properly. It is one of the most common uPVC faults, and it is usually repairable without replacing the whole mechanism or the door.
Do I need a whole new mechanism or just the gearbox?
Usually not a whole mechanism. On most uPVC doors the gearbox at the centre fails while the locking strip and its hooks carry on working, so a gearbox on its own is the usual repair when the strip is sound. Replacing the complete mechanism is generally only necessary after physical damage, where there is corrosion, or where the system is obsolete and parts are no longer made.
Does a broken uPVC lock mean I need a new door?
Almost never. A failed gearbox, a worn cylinder or a door that has dropped on its hinges are lock and hardware faults, not door faults. A locksmith can put all three right at a fraction of the cost of a replacement door. It is worth having the lock looked at before you price a new door with a window company.
Why do I have to lift and shove the handle to lock my door?
A dropped door or a moved frame. Either way, the locking hooks no longer engage cleanly with the keeps, so locking takes force. Initially the problem is alignment rather than the lock. But the repeated strain of forced lifts is what eventually breaks a gearbox, so an alignment adjustment now is far cheaper than a mechanism replacement down the line.
How long does a uPVC lock repair take?
It varies with the repair. An alignment adjustment varies according to how far the door has dropped or moved. We give you the likely duration at the same time as the price.
How long should a uPVC door lock last?
It varies a great deal. Heavy daily use shortens a multipoint gearbox's life, and so does poor alignment. A door that has needed a lift and a shove for years will have worn its mechanism much faster than one that has always closed cleanly. If yours has started to stiffen, having the alignment checked can help the lock last longer.
Can you get me in if the door is locked shut and will not open?
Yes. A door that is locked shut normally has a seized gearbox or a hook that has jammed, and the cylinder is rarely the cause. We work to release the mechanism, aiming to limit avoidable damage, but damage-free entry cannot always be guaranteed. Please ring before forcing anything, since forcing a jammed multipoint can turn a gearbox repair into a full mechanism replacement.
Should I use WD40 on a stiff uPVC lock?
Not for lubrication. WD40 works as a cleaner and water displacer, not as a long-term lubricant, and it can attract dirt into the lock as time goes on. Reach for a dry graphite or silicone lubricant. When the handle stays stiff even after that, alignment or a wearing gearbox is the usual reason, and a check now can prevent a complete failure.
