uPVC Door Not Locking Properly?
HD Locksmiths Bournemouth repairs and replaces uPVC and composite door locks, including failed multipoint mechanisms, worn cylinders and doors that have dropped out of alignment. You probably do not need a new door, because most faults are a failed part inside it.
People describe a handle that lifts but the door will not lock, a handle that has gone floppy, or a key that turns without the door opening. There is no call-out charge.
What Is Your uPVC Door Doing?
On a uPVC door, the way it misbehaves is usually the best clue to what has gone wrong inside. Tell us the symptom on the phone and we can often identify the likely part before the visit, so the price you hear is closer to the mark.
The handle lifts but the door will not lock
Here the locking points may not be lining up with the keeps in the frame. The cause could be the door's alignment or a fault within the multipoint mechanism itself. Try not to keep forcing the handle, since the door and the lock need to be inspected as a pair.
The key will not turn from the outside
Stiffness from the outside may come from a worn key or from the euro cylinder. Poor door alignment, or pressure from the internal mechanism, can make the key hard to turn as well. If the lock stays stiff, leave the key alone and let the cause be confirmed before a repair or replacement is put forward.
The handle has dropped or is floppy
Loose fixings or a tired spindle can leave a handle floppy. So can a problem inside the gearbox. We check the handle and the locking mechanism together before deciding which repair is actually needed.
You have to lift and shove to get it to lock
If locking takes a hard lift or a shove, the door has usually moved relative to the frame. Every forced lift puts pressure on the locking points, which is why alignment is worth sorting before it turns into a mechanism fault.
The door will not open though the key turns
A key that turns is no guarantee the full locking system is doing its job. The cylinder, the latch or the central gearbox may be at fault. Stop if you feel strong resistance in the key or handle; pushing on adds strain to the mechanism.
When the door is locked shut and will not open at all
A fault in the cylinder or internal mechanism may stop the door opening, and poor alignment can put extra load on the locking points. We choose an opening method according to what has gone wrong and the condition of the door. A locksmith can assess the door and choose a method intended to limit avoidable damage while getting you back in, but damage-free entry cannot be guaranteed in every case.

You Usually Do Not Need a Whole New Mechanism
When a multipoint lock stops working, the failure is normally inside the central gearbox rather than somewhere along the full-height locking strip. If the strip and its hooks are still sound, the gearbox can usually be replaced on its own, and that is a materially cheaper job than swapping the entire mechanism.
There are honest exceptions. A full strip replacement genuinely is needed after physical damage from a forced entry, where corrosion has set in, or where the system is obsolete and its gearbox is no longer made. Gearboxes also come in a number of UK families and backset sizes, so identifying the exact one on site is what decides whether the repair can be finished on the same visit.
uPVC Door: The Three Parts That Fail
It helps to stop thinking of a uPVC lock as a single part. It is three systems, each with its own failure pattern and its own price to fix, and telling them apart is the first job on any call in Bournemouth.
The euro cylinder
You use the euro cylinder every time you turn your key. It works with the central gearbox, but it can often be swapped on its own: in suitable cases, the gearbox and complete multipoint mechanism do not need changing. Correct sizing and compatibility with the existing lock and the door's protective hardware must be ensured for whatever is fitted. The cylinder's cost depends on its required size and security rating.
The alignment of the door
Alignment is a separate matter from the lock, yet it controls how the locking points meet the keeps in the frame. If the door has moved, the key or handle can become difficult to operate, and an adjustment may be needed even though the lock has not completely failed. Some lock faults are caused or made worse by poor alignment, so the price depends on the cause and the adjustments required. Where the door has significant damage or structural problems, separate work from a door specialist may be required.
Multipoint gearbox
The gearbox transfers movement from your key and handle to the multipoint system; when it develops a fault, the door may not lock or unlock correctly. Sometimes the gearbox can be replaced without the complete strip, subject to compatibility and the condition of the remaining mechanism. The strip runs along the edge of the door and operates hooks, rollers or bolts, depending on the system. If several parts are damaged, or a compatible gearbox-only repair is unsuitable, the complete strip may have to be replaced. Whether a separate gearbox is possible shapes the price, because a full strip involves different parts and fitting work; compatibility and component availability affect it too.
Upgrading the Cylinder While We Are There
The euro cylinder is the part you put your key into, and in suitable cases it can be replaced without touching the gearbox or the full multipoint mechanism. A new one may be needed because the old cylinder is damaged, unreliable or the wrong size, and some customers choose to replace it so they can consider a recognised security-rated option. If a cylinder is being changed anyway, upgrading to an anti-snap rated one adds little to the job; it is a recommendation, not a requirement, and a standard cylinder can still be replaced like for like if you prefer.
Ratings to look for.
Some cylinders are certified to recognised security standards, and options may include TS 007 three-star and SS 312 Diamond-rated cylinders. You can check yours now: look at the cylinder face for a star rating or a Diamond mark.
Fit still comes first.
A rating does not make every cylinder suitable for every door. It must be the correct size and work with the existing lock and any protective hardware around it.
Insurance.
Some policies specify a lock or cylinder standard, so check the exact wording, or ask your insurer to confirm its requirements before you choose.
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.

How Much Does a uPVC Door Lock Repair Cost?
Prices for uPVC lock work in Bournemouth vary with the job, so there is no single fixed price for every repair. What you pay depends on the fault, any replacement parts and the work required, and the answer could be an adjustment, a repair or a replacement component. A cylinder costs differently from gearbox or complete-mechanism work, and door alignment can also affect the repair needed. Five things shape the figure:
- Which part has failed
- Whether the gearbox can be replaced on its own or the full strip is needed
- Whether you upgrade the cylinder
- Whether the door also needs realigning
- The time of day
As a guide, a cylinder replacement is the least costly outcome and a complete mechanism the most, with a gearbox-only repair in between. We work on uPVC and compatible composite doors, assess lock and door alignment, and explain your repair and replacement options. There is no call-out charge, and a price is given on the call. Tell us what the key and handle do and whether the door opens, closes and locks normally, and your description lets us price the work on that call. The inspection identifies the fault and whether adjustment, repair or a compatible replacement part is required; the call price stands unless the job differs on site, and you hear about any change before work starts, with your approval needed for the work. Once finished, the key, handle and locking operation are tested, and alignment and locking-point engagement checked where relevant. You pay for the work carried out, any parts needed, and VAT, and the bill is built from those alone. Rates outside Monday to Friday, 7am to 6pm, are higher, but the call-out itself is never charged, whenever the call comes in.
What affects the cost?
Service required, time of attendance, lock and door type, labour and parts.

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.
What affects the cost?
Service required, time of attendance, lock and door type, labour and parts.
Composite Doors Too
Composite and uPVC doors often share the same kind of euro cylinder and multipoint mechanism, so we repair both. On a composite, a fault may affect the key, the handle or the locking points, and the door's alignment can also stop the mechanism working. A denser, harder-to-work slab and more variable hardware sizing mean the construction and fittings are assessed first, before any compatible repair or replacement is recommended.

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?
Just the gearbox, as a rule. It is the part that usually fails, and the full-height locking strip and hooks are often still sound; when they are, a gearbox replacement is enough, subject to compatibility. The exceptions are physical damage, corrosion, or an obsolete system whose gearbox is no longer made, and in those cases the complete mechanism is the honest recommendation.
Does a broken uPVC lock mean I need a new door?
Hardly ever. What looks like a broken door is usually a broken lock: a failed gearbox, a worn cylinder or hinges that have let the door drop. All of these are hardware faults, and putting them right costs a fraction of a replacement door. Get the lock inspected before speaking to a window company about a new one.
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?
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?
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?
Usually, yes. When a uPVC door is stuck locked, the cause is normally a seized gearbox or a jammed hook, not the cylinder. Our approach is to release the mechanism rather than damage the door, although no one can guarantee damage-free entry in every case. Call us before you force it: forcing a jammed multipoint can turn a gearbox repair into a whole new mechanism.
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 Bournemouth can head off a full failure.
