uPVC Door Not Locking Properly?
Martin Locksmiths Normanton repairs and replaces uPVC and composite door locks across Normanton, including failed multipoint mechanisms, worn cylinders and doors that have dropped out of line. Chances are you do not need a new door, because most faults are a failed part inside it.
What people tell us: 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. More on diagnosis and repair is on our uPVC door locks page.
What Is Your uPVC Door Actually Doing?
Most uPVC faults announce themselves through a symptom you will recognise, and that symptom usually points to the part that has failed. Describe what the door is doing and we can often narrow the fault down before we arrive, which means a more accurate price on the call.
When the handle lifts but the door will not lock
When the handle goes up but the key will not throw the lock, the locking points may not be meeting the keeps correctly. Either incorrect door alignment or an internal fault in the multipoint mechanism can explain that. Avoid forcing the handle again and again; the door and lock should be inspected together.
The handle has dropped or feels floppy
A handle that droops may simply have loose fixings or a worn spindle. It can also be a sign of trouble inside the gearbox. Because those causes look alike from outside, the handle and locking mechanism are checked together before the right repair is decided.
The key turns, but the door will not open
A key that rotates freely does not prove the whole locking system is working. The cylinder, latch or central gearbox may be where the fault lies. If the key or handle meets strong resistance, stop there, because extra force puts more strain on the mechanism.
A door locked shut that will not open at all
A cylinder or internal mechanism fault can stop the door opening, and poor alignment can add pressure on the locking points. A locksmith can inspect the door and work out an appropriate opening method, which depends on the fault and the door's condition. The aim is to regain access while limiting avoidable damage, though damage-free entry cannot be guaranteed in every situation.
It only locks if you lift and shove
Needing to heave the handle up, or lean on the door, usually means the hooks and keeps have drifted out of line. That misalignment loads the locking points every time you lock up, so it is worth having it looked at early.
The key will not turn from outside
A key that sticks on the outside may point to the key itself or the euro cylinder. Turning can also become difficult when poor alignment or the internal mechanism creates pressure. Do not force a stiff key; the cause should be confirmed before any repair or replacement is recommended.

And You Almost Certainly Do Not Need a New Door
The double glazing company that fitted your door is a natural first call, but it is the wrong one for most lock faults. They fit doors; locksmiths fix locks. A failed gearbox, worn cylinder or dropped door costs a fraction of a new door to put right. In some cases just one part of the uPVC system needs attention, and the option chosen depends on the fault plus the compatibility and condition of everything else in the mechanism. Often the central gearbox is the only part stopping the lock, and sometimes a compatible gearbox can be fitted without the complete multipoint strip being changed, subject to the gearbox model and the condition of the remaining components. Where several components are worn or damaged, or the strip has failed and no suitable gearbox-only option exists, the complete strip may need replacing, and any replacement mechanism has to be compatible with the door and its locking arrangement. Occasionally it is the door that prevents the lock working correctly. We can assess how its condition affects locking; severe warping or damage to the profile may require more than an adjustment or a replacement component, and wider structural repairs may require a suitable door specialist. In every case we assess the complete locking operation before recommending the work required.
Three Parts That Fail on a uPVC Door
A uPVC door lock is not one component but three, and they fail in different ways. That distinction is the difference between a modest repair and a much larger job, so it pays to know which is which.
Door alignment
How the door hangs is separate from the lock, yet it controls whether the locking points meet the keeps in the frame. When alignment is poor, the key or handle becomes hard to operate, and an adjustment may be needed before the mechanism has properly failed. Because some lock faults are caused or made worse by alignment, pricing follows the cause and the adjustments required. Where there is significant damage or a structural door problem, separate work from a door specialist may be needed.
Euro cylinders
The euro cylinder is the key-operated part. It works alongside the central gearbox, yet it can often be changed separately; in suitable cases, there is no need to replace the gearbox or the complete multipoint mechanism. The fitted lock and protective door hardware must be compatible with a new cylinder, which must also be the correct size. Size and security rating both influence what a cylinder costs.
The multipoint gearbox
The gearbox converts movement of the key and handle into movement along the multipoint system, and a fault there can stop the door locking or unlocking correctly. In some cases it can be replaced without changing the full strip, which depends on compatibility and the condition of what remains. The strip runs down the door edge, operating hooks, rollers or bolts according to the system. If several parts are damaged, or a compatible gearbox-only repair is unsuitable, the whole strip may need replacing, which involves different parts and fitting work. Whether the gearbox can go in on its own drives the price, and so do compatibility and the availability of components.
Usually, You Do Not Need a Whole New Mechanism
If your uPVC lock has failed, the odds are that the problem is inside the gearbox at the centre of the door, not spread along the full-height locking strip. Provided the strip and hooks are sound, the gearbox can usually be replaced on its own, and that costs materially less than replacing the whole mechanism.
We are straightforward about the exceptions. The full strip needs replacing when it has been physically damaged by a forced entry, when it is corroded, or when the system is obsolete and a replacement gearbox is no longer made. Our lock replacement page covers the wider choices.
And Composite Doors Too
Composite doors in Normanton get the same service as uPVC. Many use euro cylinders and multipoint mechanisms similar to a uPVC door's, so faults may appear in the key, the handle or the locking points, and poor alignment can also prevent the mechanism working. Their slabs are denser and harder to work on, and hardware sizes vary more widely, so we assess the construction and fittings before recommending a compatible repair or replacement.
How Does the Job Work?
- Likely fault, then price. We identify the probable cause and give you a figure.
- Finished and tested. The repair is completed, the door is locked and unlocked from both sides, and the alignment is checked.

While We Are There, Upgrading the Cylinder
Should you upgrade the cylinder while it is out? We think it is worth considering, because the extra work involved is small, but it is a recommendation and never a condition; a standard cylinder can be replaced like for like. The euro cylinder is the key-operated part of the lock, and in suitable cases it can be replaced without changing the gearbox or the complete multipoint mechanism. Reasons to replace include damage, unreliability or incorrect sizing, and some customers do so to consider a recognised security-rated option.
For background, see anti-snap locks and lock snapping explained.
Look at your cylinder face
for a star rating or Diamond mark. Some replacement cylinders are certified to recognised security standards, and options may include TS 007 three-star and SS 312 Diamond-rated cylinders.
A rating is not a fit.
No security rating makes a cylinder suitable for every door. Both its size and its compatibility with the installed lock and surrounding protective hardware must be correct.
Check your policy.
Some policies specify a lock or cylinder standard; check the exact wording, or ask your insurer to confirm its requirements before choosing.

What Does a uPVC Door Lock Repair Cost?
We do not publish one price for uPVC lock repairs, because one price would not be true for every job. The cost depends on what has failed, which parts are needed and how much work is involved; the fix may be an adjustment, a repair or a replacement component. Here are the factors that matter most:
Of the outcomes, a cylinder swap is the cheapest, a gearbox-only repair is in the middle and a full mechanism is the most expensive. We handle uPVC and compatible composite doors, assessing the lock and door alignment and explaining the repair and replacement options. No call-out charge applies, and the price is given to you on the call. Tell us what happens when you use the key and handle, and whether the door opens, closes and locks normally, and we give you a price from that description on the call. Inspection identifies the fault and whether an adjustment, repair or compatible replacement part is required. We keep to the phone price unless the job differs on site; any change is explained before work starts, with your approval required. We complete it, test the key, handle and locking operation, and check alignment and locking-point engagement where relevant. To be clear on the bill: You pay for the work carried out, any parts needed, and VAT. Rates outside Monday to Friday, 7am to 6pm, are higher, but the call-out itself is never charged, at any hour.

Frequently Asked Questions
My uPVC door handle has dropped and will not lift. What is wrong?
In most cases, a failed gearbox. The handle relies on the gearbox for its tension, so when the internals give way it hangs down and will not lift. Do not assume the door is unlocked: the hooks and bolts can still be engaged. Because this is such a common fault, it is usually fixed by repair rather than by replacing the full mechanism or the door.
Do I need a whole new mechanism or just the gearbox?
In most cases the gearbox alone will do. Failures on uPVC doors usually happen inside the central gearbox, not along the full-height strip. If the strip and hooks are in sound condition, replacing just the gearbox is the normal fix. You would need the whole mechanism after physical damage, after corrosion, or where the system is obsolete and the part has stopped being made.
Does a broken uPVC lock mean I need a new door?
No, in the vast majority of cases. Failed gearboxes, worn cylinders and dropped doors are lock and hardware faults that a locksmith repairs at a fraction of the cost of replacement. Window companies fit doors; locksmiths fix locks. It makes sense to have the lock looked at before you start pricing a new door.
Why do I have to lift and shove the handle to lock my door?
Because the hooks and keeps have drifted apart. The door may have dropped, or the frame may have moved, and either way it is an alignment problem first and a lock problem second. That second part matters: forcing the handle up repeatedly strains the gearbox until it fails, so sorting the alignment now costs far less than a new mechanism later.
How long does a uPVC lock repair take?
Usually not long, though the answer varies by job. Alignment work depends on how far the door has shifted. When we quote, we also confirm how long the job is likely to take.
How long should a uPVC door lock last?
Lock life is set less by the calendar than by use and alignment. A frequently used door wears its gearbox faster, and a door left out of alignment for years wears its mechanism considerably faster than one that closes cleanly. That is why adjusting a door as soon as it starts to drop is one of the best ways to extend the life of the lock.
Can you get me in if the door is locked shut and will not open?
Yes, in most cases. A uPVC door that is locked shut is usually a seized gearbox or a jammed hook rather than a cylinder problem, and we aim to open it by releasing the mechanism, limiting avoidable damage, though damage-free entry cannot be guaranteed every time. Please call before forcing it, because forcing a jammed multipoint can turn a gearbox repair into a full mechanism replacement.
Should I use WD40 on a stiff uPVC lock?
Not as a lubricant. WD40 is a cleaner and water displacer rather than a lasting lubricant, and over time it can attract dirt into the mechanism. A dry graphite or silicone lubricant is the better choice. If the handle is still stiff after lubricating, the cause is usually alignment or a wearing gearbox, and it is worth getting checked before it fails completely.
