uPVC Door Not Locking Properly?
In Farnborough, Wilds Locksmiths Farnborough repairs and replaces uPVC and composite door locks, whether the fault is a failed multipoint mechanism, a worn cylinder or a door that has dropped out of line. You probably do not need a new door; usually one part inside it has failed.
Decide first whether to call now or book. If the door will not secure tonight, call. If the handle lifts but nothing locks, the handle is floppy, or the key turns yet the door stays shut, stop forcing it. There is no call-out charge.
What Exactly Is Your uPVC Door Doing?
uPVC doors give fairly honest warning signs. The symptom you describe usually tells us which part has failed before we are on the doorstep, and that lets us give a more accurate price over the phone.
The door is locked shut and will not open at all
When a uPVC door is stuck shut, a cylinder or internal mechanism fault may be preventing it opening. The locking points can also come under pressure when alignment is poor. A locksmith can look at the door and decide on a suitable way in, based on the fault and the door's condition, with the aim of regaining access while limiting avoidable damage. Damage-free entry is not something anyone can promise in every situation.
A handle that has dropped or feels floppy
A loose handle may come down to its fixings or spindle, though the wobble can also come from a problem inside the gearbox. We look at the handle and locking mechanism together before settling on the required repair.
To get it to lock you have to lift and shove
That extra effort usually means the door has dropped and the hooks no longer sit cleanly in the keeps. The poor alignment puts pressure on the locking points every time.
When the key turns but the door will not open
A turning key is not always a sign that the whole locking system is working. The cylinder, latch or central gearbox may be involved in the fault. If the key or handle meets strong resistance, stop: more force could place more strain on the mechanism.
The handle lifts, but the door will not lock
The locking points may not be meeting the keeps correctly, which can indicate a door-alignment problem or a fault in the multipoint mechanism. Avoid repeatedly forcing the handle, and have the door and lock inspected together.
From outside, the key will not turn
The key or the euro cylinder may be involved. A door out of alignment, or pressure from the mechanism inside, can make turning difficult too. Do not force a key in a lock that stays stiff; get the cause confirmed before any repair or replacement is recommended.

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 Usually Do Not Need a Whole New Mechanism
Quoting for a full mechanism when only the gearbox has failed is the difference between an honest price and an inflated one. On a typical uPVC door the fault sits inside the central gearbox, not along the full-height strip, and if the strip and hooks are sound the gearbox alone can usually be replaced for materially less.
Sometimes a whole strip really is the right call. That applies where a forced entry has physically damaged it, where corrosion has taken hold, or where the system is obsolete and the gearbox is no longer made.
Composite Doors as Well
We repair composite door locks alongside uPVC ones. Many composite doors carry euro cylinders and multipoint mechanisms close to those in uPVC, so problems can sit in the key, handle or locking points, or come from poor alignment stopping the mechanism. What changes is the slab, which is denser and harder to work on, and hardware sizing, which varies more; both are assessed before a compatible repair or replacement is recommended.
And You Almost Certainly Do Not Need a New Door
Plenty of people with a failed uPVC door ring the company that fitted it, or start pricing a new door. Window companies fit doors; locksmiths fix locks. A failed gearbox, a worn cylinder or a dropped door are lock and hardware faults, and putting them right costs a fraction of a replacement door. Often only one part of the locking system needs attention, and the right option depends on the fault, on compatibility and on the condition of the rest of the mechanism. The central gearbox may be the only thing stopping the lock working, and a compatible one can sometimes be fitted without changing the whole multipoint strip, depending on the gearbox model and the state of the other components. The complete strip may need replacing if several components are worn or damaged, or if it has failed and no suitable gearbox-only option exists; any replacement must suit the door and its locking arrangement. Sometimes the door itself stops the lock working. We can assess how its condition affects the locking, but severe warping or damage to the profile may need more than an adjustment or a new component, and wider structural repairs may call for a suitable door specialist. Before we suggest any work, we check how the locking system functions as a whole.

What Is the Cost of a uPVC Door Lock Repair?
How much will it cost? Honestly, it depends, because there is no single fixed price for every uPVC door lock repair. The fault, any replacement parts and the work required all shape the figure, and the answer may be an adjustment, a repair or a new component. The factors explained here are the ones that move the price:
- Which part has actually failed
- Whether the gearbox can be replaced separately or the whole strip has to go
- Whether you decide to upgrade the cylinder
- Whether the door also needs realigning
- What time of day the work is done
A cylinder replacement is the cheapest result, a complete mechanism the dearest, and a gearbox-only repair falls in between; alignment can also change what is needed. For uPVC and compatible composite doors we assess the lock and the door alignment and explain the repair and replacement options. Call-outs are free, and the price comes on the call. Let us know what happens when you use the key and handle and whether the door opens, closes and locks normally; that description gives us the basis for your price on the call. The inspection identifies the fault and shows whether adjustment, repair or a compatible replacement part is needed. Your call price holds unless the job differs on site; changes are explained before work starts, subject to your approval. Once the approved adjustment, repair or replacement is done, we test the key, handle and locking operation, and check alignment and locking-point engagement where relevant. You pay for the work carried out, any parts needed, and VAT, with no extra fee for the visit. Rates outside Monday to Friday, 7am to 6pm, are higher, but the call-out itself is never charged, weekday or weekend.
What affects the cost?
Service required, time of attendance, lock and door type, labour and parts.

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.
uPVC Door Lock Repairs Across Farnborough
We repair uPVC and composite door locks for homeowners, landlords and businesses across Farnborough. Much of the housing suits that work: 47.5% of homes were built from 1945 to 1982, 23.2% from 1983 to 2008 and 12.9% since 2009, against 4.8% before 1900 and 10.7% from 1900 to 1939 (VOA council tax property stock, 31 March 2026). Those are the periods in which uPVC doors with multipoint locks tend to appear.
The visits cover every postcode in GU14, including South Farnborough, North Farnborough, North Camp, Cove, Fox Lane and West Heath, in a built-up area of around 60,700 usual residents at the 2021 Census (ONS). Cove is mostly houses, and North Camp has a high share of private renting (Census 2021, ONS; indicative), so some doors are a household's own and others sit in a rented home.
How a door behaves hints at the fault. If you have to lift or push it before it locks, the locking points may not be engaging, often because the door has shifted on its hinges; a visit is needed to confirm.
How the Job Works
- Get a price. We identify the likely fault from what you describe and give you a price.
- Repair and test. The repair is completed and the door is tested locking and unlocking from both sides, with the alignment checked.

Frequently Asked Questions
My uPVC door handle has dropped and will not lift. What is wrong?
By far the likeliest culprit is the multipoint gearbox, though we always confirm it first. An internal failure leaves the handle with no engagement, so it drops and will not lift. Expect the door to possibly stay locked, because the hooks and bolts can remain engaged. As common uPVC faults go, this one is usually repairable without a whole new mechanism or door.
Do I need a whole new mechanism or just the gearbox?
Probably only the gearbox. The central gearbox is where most uPVC multipoint failures happen, rather than along the strip that runs the height of the door. With a sound strip and hooks, the gearbox can be replaced by itself. A whole new mechanism is normally reserved for physical damage, corrosion, or obsolete systems where a replacement gearbox is no longer available.
Does a broken uPVC lock mean I need a new door?
Almost certainly not. When a uPVC lock fails, the cause is nearly always hardware: the gearbox, the cylinder, or a door that has dropped on its hinges. A locksmith fixes all of these for a fraction of the price of a new door. Have the lock checked first, and only price a new door if that check finds something more serious.
Why do I have to lift and shove the handle to lock my door?
The hooks are no longer lining up with the keeps, usually because the door has dropped on its hinges or the frame has moved. It starts as an alignment issue, not a lock fault. Keep forcing it, though, and the gearbox takes the strain until it fails, which is why getting the alignment adjusted early is the far cheaper option.
How long does a uPVC lock repair take?
Alignment adjustments vary with how far the door has moved. We confirm the likely length of the job when we price it.
How long should a uPVC door lock last?
There is no fixed lifespan: it depends heavily on how often the door is used and whether its alignment has been correct. A door that closes cleanly puts far less wear on its multipoint gearbox than one that has been out of alignment for years, which will wear its mechanism out considerably faster. Keeping the door adjusted is the best way to make the lock last.
Can you get me in if the door is locked shut and will not open?
Yes, we can normally get you in. A uPVC door locked shut is most often a seized gearbox or a jammed hook, which we tackle by releasing the mechanism with the aim of limiting avoidable damage, though damage-free entry cannot be guaranteed. Call before forcing the door: forcing a jammed multipoint can turn what would have been a gearbox repair into a full mechanism replacement.
Should I use WD40 on a stiff uPVC lock?
Not really. WD40 cleans and displaces water but does not lubricate for long, and it can attract grime into the mechanism. A dry graphite or silicone lubricant works better on a uPVC lock. If stiffness returns or never goes, alignment or a wearing gearbox is the usual cause, and having it checked early in Farnborough can head off a full failure.
