uPVC Door Not Locking Properly?
A new door is probably unnecessary. Craven Locksmiths Wilmslow repairs and replaces uPVC and composite door locks, covering failed multipoint mechanisms, worn cylinders and doors that have dropped out of alignment, because the fault is normally a failed part inside the door.
Typical complaints: the handle lifts but the door will not lock, the handle has gone floppy, or the key turns yet the door will not open. There is no call-out charge.
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.

Almost Certainly, You Do Not Need a New Door
When a uPVC door fails in Wilmslow, many people's first instinct is to call the installer or price up a new door. A locksmith is usually the better call: window companies fit doors, locksmiths fix locks, and a failed gearbox, worn cylinder or dropped door is fixed for a fraction of the cost of a replacement door.
Often only one part of the locking system needs attention, and the right option depends on the fault as well as the compatibility and condition of the rest of the mechanism. The central gearbox may be the only part preventing the lock from working, and a compatible unit can sometimes be fitted without changing the complete strip, depending on its model and the condition of the remaining components. When several components are worn or damaged, or the strip has failed and a suitable gearbox-only option is unavailable, the complete strip may need replacing; the replacement must be compatible with the door and its locking arrangement. Sometimes it is the door that prevents the lock working. We can assess how the door's condition affects its locking operation, though severe warping or damage to the profile may require more than an adjustment or a replacement lock component, and wider structural repairs may require a suitable door specialist. Any recommendation we make about the work needed always follows a full assessment of the locking operation.
Upgrading the Cylinder While We Are There
A cylinder replacement is the one moment when upgrading security is almost effortless. The euro cylinder, the part your key slides into, can often be changed without replacing the gearbox or complete multipoint mechanism in suitable cases, so the work is already happening. You might be replacing it because it is damaged or unreliable, because it is the wrong size, or because you want to consider a recognised security-rated option. We suggest an anti-snap rated cylinder, though a like-for-like standard cylinder remains available if that is what you would rather have.
Ratings.
Certain cylinders hold certification to recognised security standards, so options may include TS 007 three-star and SS 312 Diamond-rated cylinders. Your current cylinder's face will show a star rating or Diamond mark if it has one.
Fit.
A security rating does not mean the cylinder suits every door. The replacement has to be the right size for your door and compatible with the existing lock and protective hardware.
Cover.
Where your insurance policy specifies a lock or cylinder standard, read the exact wording, and ask your insurer to confirm its requirements before you pick a replacement. Some policies specify one; not all do.
Three Parts That Fail on a uPVC Door
When a uPVC door stops behaving, it is tempting to assume the whole lock has gone. Usually one of three distinct systems is responsible, and which one it is makes a large difference to the work and the bill.
The multipoint gearbox
At the centre of the door edge, the gearbox takes the movement of the key and handle and passes it along to the multipoint system. A fault inside it can stop the door locking or unlocking as it should. Whether it can be replaced on its own, leaving the complete multipoint strip in place, depends on compatibility and on the condition of the remaining mechanism. That strip runs along the edge of the door and, system by system, works hooks, rollers or bolts. If several of its parts are damaged, or a compatible gearbox-only repair is not suitable, the complete strip may need replacing. Pricing follows that choice: a full strip means different parts and fitting work, and compatibility and the availability of parts can also move the final figure.
Euro cylinders
The euro cylinder is the key-operated part. It works together with the gearbox but, in suitable cases, it can be replaced without changing the gearbox or the full multipoint mechanism. Correct sizing and compatibility with the existing lock and protective door hardware must be ensured for the new one. Size and security rating set the cost.
Door alignment
Alignment is not part of the lock, but it decides how the locking points meet the keeps. A poorly aligned door can make the key or handle hard to use, and it may need adjusting before the mechanism has failed outright. Some lock problems are caused or worsened by alignment, so the price depends on the cause and the adjustments needed; significant damage or structural door problems may need separate work from a door specialist.

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 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.
Locksmith pricing
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.
The failed part.
The cost of gearbox or complete-mechanism work differs from the price of a cylinder.
Gearbox versus strip.
Whether the gearbox alone can be replaced.
Cylinder choice.
Whether you upgrade to a security-rated cylinder.
Alignment.
Whether the door needs realigning as well, since alignment can change the repair.
Timing.
The time of day the job is done.
How Does the Job Work?
Two steps, start to finish:
- We name the likely fault and give you a price.
- We finish the repair, then test the door locking and unlocking on both sides and check how it is aligned.

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?
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?
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?
Your door is out of alignment. Either it has dropped or the frame has shifted, and the hooks are missing the keeps. To begin with that is not a lock fault at all. The trouble is that each hard lift strains the gearbox, and over time that strain is what breaks it, so an alignment adjustment now costs far less than a new mechanism later.
How long does a uPVC lock repair take?
It depends on the part. An alignment adjustment varies with how far the door has moved. We confirm the likely job length when we give you the price.
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, usually. Locked-shut uPVC doors tend to have a seized gearbox or a jammed hook rather than a cylinder fault. We open them by releasing the mechanism where possible, limiting avoidable damage, though damage-free entry cannot be promised every time. The most useful thing you can do is call before forcing it, because force can turn a gearbox repair into a complete mechanism job.
Should I use WD40 on a stiff uPVC lock?
We would not recommend it as a lubricant. WD40 is a water displacer and cleaner, not something that lubricates for long, and it can attract dirt into the mechanism over time. Graphite or silicone, applied dry, does the job better. A handle that stays stiff after lubricating usually points to alignment or a wearing gearbox and should be checked before it fails.
