uPVC door lock and mechanism repairs
Diagnosis and repair of multipoint locking mechanisms, cylinders, handles, hinges and door-alignment problems.
A uPVC lock problem is not always just the cylinder
uPVC doors rely on several components working together. A fault may involve the multipoint mechanism, gearbox, cylinder, handles, keeps, hinges or the alignment of the door itself.
Continuing to force a stiff handle or key can increase the damage. An assessment can identify the likely cause and whether adjustment, component repair or replacement is appropriate.
Common reasons to call
- Handle will not lift
- Key will not turn
- Door only locks when lifted
- Mechanism feels stiff
- Door catches on frame
- Handle or cylinder is loose

Frequently asked questions
Why does my uPVC door only lock when I lift it?
Some movement is normal, but excessive lifting or force may indicate alignment or mechanism wear.
Does the whole mechanism need replacing?
Not always. The correct solution depends on which component has failed and the condition of the remaining hardware.
Should I stop using a stiff lock?
Avoid forcing it. Continued pressure can turn a smaller adjustment or component fault into a more extensive failure.
