Locks when open, but not when closed
Often points to alignment or a dropped door: the locking points may not line up with the keeps in the frame. It does not automatically mean the lock has failed.

What is your door doing?
Describe the symptom in your own words. These are clues to the likely fault, not a diagnosis: the door and locking system need checking before deciding which parts, if any, to replace.
The handle will not lift
Could be resistance from alignment, a worn gearbox or a multipoint mechanism fault. Forcing the handle can add strain to parts that are already struggling.
The handle lifts, but the lock will not engage
The movement may not be reaching the locking points. The gearbox, strip and alignment need checking rather than assuming that the visible handle is the cause.
The key turns or spins, but nothing happens
A cylinder, gearbox or internal mechanism fault can cause this. Tell me whether the door is open or shut and whether the handle still moves.
The door is jammed shut
A failed mechanism may have left the locking points engaged. Restoring access comes before inspecting the fault; non-destructive entry is attempted wherever practical.
You need to push or pull the door to lock it
This can indicate a dropped door, misaligned keeps or resistance in the mechanism. The fit of the door needs checking alongside the lock.
This includes back doors, double glazed doors, patio and French doors, as well as sliding patio door lock faults. If the door is insecure now, call before forcing it.
What can cause the problem?
A similar symptom can come from different components. I check how the door fits its frame and how the handle, cylinder and locking points work together.
Alignment
A dropped door, worn hinges or misaligned keeps can stop hooks and rollers meeting the frame correctly. If the lock works with the door open but struggles when closed, adjustment may be the right repair.
Gearbox / centre case
The centre case transfers movement from the handle and key to the locking system. Wear or failure here can stop the other locking points moving, even when the cylinder still turns.
Multipoint mechanism
The strip connects the locking points along the door edge. I check whether a failed centre case can be replaced separately or whether wear or damage calls for a correctly sized replacement mechanism.
Cylinder, handle or spindle
The key operates the cylinder; the handle and spindle pass movement into the lock. A fault in one of these components may need a targeted replacement rather than a complete multipoint strip.
An awkward handle or key is a reason to have the door assessed. Repeated force adds stress to the mechanism and can make an existing problem worse.
How I diagnose and repair it
You do not need to name the part. Explain whether the problem started suddenly or became gradually stiffer, and whether the door is currently open, shut or insecure. A photo helps identify visible hardware, but cannot confirm the condition of the components inside.
Tell me the symptom
Give your postcode, the door type and whether it will lock, open or move at all.
Send a photo if useful
A photo of the handle, lock face or accessible door edge can help with preparation; don’t force the door for a photo.
Check the actual fault
On site, I assess alignment and the locking components; if the door is jammed, access comes first.
Agree the repair
I explain the repair or replacement options and price before work, then check that the door and lock operate correctly.
A Fault Doesn’t Automatically Mean You Need a New Door
Many uPVC and composite door problems come from adjustment or an individual component, rather than the whole door failing. The door may need alignment, a gearbox or centre case, a multipoint strip, a cylinder, or handle and spindle work.
Where practical, I repair or replace the failed component and keep the parts that still work. A full mechanism replacement can be sensible when the strip or locking points are too worn to save; it is not the starting assumption for every stiff handle.
Once the repair is complete, the door needs to close, lock and open correctly. Replacing a part without checking alignment can leave resistance in the system, so the fit of the door matters as well as the lock.
Not every door or lock is repairable. Once I have checked the actual condition, I’ll explain what can be kept, what needs replacing and why.

No call-out fee. No VAT. The final price depends on the fault and any parts required.
Alignment work, a cylinder replacement, a gearbox and a full multipoint mechanism are different jobs. Parts are priced against the component that is actually needed, rather than assuming a fixed total before the door has been assessed.
Call with your postcode and symptom, or send useful photos on WhatsApp. I’ll explain the next step and give you a clear price before work starts.
Any replacement part fitted is covered by a 1-year warranty.

Difficult to lock; handle not engaging
The fault was traced to the gearbox and multipoint mechanism. The failed part was replaced, the keeps were checked, and the door was tested so it locked smoothly again.

On this Leeds uPVC repair, the failed parts were confirmed before the handle and lock were replaced.

Questions about uPVC door repairs
Why won’t my uPVC door lock?
Alignment, a worn gearbox, a failed multipoint mechanism or a cylinder fault can all stop a door locking. I check the door and components before recommending a repair; the symptom alone does not confirm which part has failed.
Why does my door lock when open but not when closed?
This often points to the door and frame no longer lining up correctly. A dropped door or misaligned keeps can prevent the locking points engaging. The fit and the mechanism need checking before deciding whether adjustment is enough.
Does a handle that won’t lift mean the gearbox has failed?
Not necessarily. Alignment or resistance elsewhere in the mechanism can also stop the handle lifting. Avoid forcing it; the gearbox, locking points and door alignment need checking together.
Can a multipoint door mechanism be repaired?
Sometimes adjustment or replacement of the failed centre case is enough. If the strip or locking points are too worn or damaged, a correctly sized replacement mechanism may be needed. That still does not automatically mean replacing the whole door.
Can you open a jammed uPVC door?
Yes, I attend doors stuck shut in Leeds. Non-destructive entry is attempted wherever practical. If another method is needed, I explain why before starting; the underlying lock fault can be assessed once access is restored.
How much does a uPVC door repair cost?
Labour starts from £60, with no call-out fee and no VAT. Parts depend on the fault. Tell me your postcode and what the door is doing for advice and a clear price before work.
Do I need to replace the whole door?
Many faults can be dealt with through alignment or a replacement lock component. A new door is not the default solution, but not every door can be repaired. I’ll explain the options after checking its condition.
Door still won’t lock?
Call your local Leeds locksmith and tell me what the door is doing. If a photo will help, send the handle, lock face or accessible door edge on WhatsApp.
