These are the faults I look for first
When someone says “my uPVC door won’t lock”, the next few details usually reveal whether the problem is the gearbox, alignment, or a worn mechanism. That is what turns a vague symptom into a sensible repair plan.
The door may only need realignment
If the door has dropped and needs lifting, a proper adjustment can restore smooth locking before the mechanism wears out further.
A replacement part can often save the door
If the strip or centre case is too worn to trust, fitting the correct part is usually far cheaper than replacing the whole door setup.
Many doors can be repaired without replacing the whole setup
The best outcome is a safe, reliable repair with the least unnecessary cost. Some jobs only need adjustment or a gearbox swap. Others need a new mechanism. The value is in knowing which is which.
Often a straightforward repair
Ideal when the door has dropped slightly, the handle is getting stiff, or one part has worn before the rest of the mechanism has failed.
Sometimes a replacement part is the right answer
If the strip has failed or the centre case is beyond a trustworthy repair, replacing the correct part gets the door working properly again.
Call before it jams shut
If the handle suddenly feels much worse or the key turns without engaging anything, waiting often turns a repair visit into an urgent entry job.
Send 2 or 3 photos and get a faster quote
A clear photo of the handle, lock face and door edge often reveals enough to narrow down the likely fault before I arrive. That means better preparation and less back-and-forth.

Frequently asked questions
My uPVC door will not lock but still opens. Is that urgent?
It can quickly become urgent if the handle is getting stiffer or the key turns without engaging the locking points. Catching it early often prevents a complete jam.
Can a locksmith usually repair a uPVC door that will not lock?
Often, yes. Alignment, gearbox swaps and correctly sized replacement parts solve many faults without replacing the whole door.
What is the most common part to fail?
The gearbox is one of the most common failures, especially where the key turns but nothing locks or the handle feels loose.
Should I keep forcing the handle?
No. Forcing a stiff handle often turns a smaller repair into a full mechanism replacement.
