Problems with your uPVC door?

A handle that will not lift or a key that turns without locking can point to different faults. The door and its mechanism need assessing together.

Common uPVC lock problems

  • The handle won’t lift or feels stiff
  • The key turns, but the door won’t lock
  • Locking works only with the door open

The assessment

Check the door before choosing the part.

A multipoint lock has several connected parts. A problem with the cylinder, gearbox or door alignment can produce similar symptoms. The door and existing hardware need checking before a repair or replacement is chosen.

Tell us about the door

The next step

Describe how the mechanism behaves.

Say whether the fault occurs with the door open as well as closed, and whether the key and handle move freely. Avoid forcing either. Compatible parts and the extent of the work depend on the actual mechanism.

Call 07337 571126 with the property location and whether the door is open, closed or locked. Let us know if you cannot secure the building.

Start with your situation

What happens when you try to lock up?

Choose the detail that sounds familiar. You don’t need the name of the lock to start the conversation.

Call to discuss your door
01It locks open, but not closed

This can point towards the way the door meets the frame rather than the cylinder alone. Tell us what you can observe without applying force; the actual door and hardware need assessing.

02The handle will not lift

Do not force the handle higher. Describe whether it moves freely, whether the door catches and when the fault began. The cause may involve alignment or the multipoint mechanism.

03The key turns but nothing locks

Explain whether the handle and the locking points move. A cylinder and a multipoint gearbox are different parts; the symptoms help guide assessment and compatible replacement choices.

Understand the work

What affects a uPVC repair quote?

The fault may involve an adjustment, a cylinder or a larger part of the mechanism. Discuss the assessment and what the quote includes before agreeing the work.

  • The actual door

    Material, condition and existing hardware determine the suitable work.

  • The right parts

    Compatible dimensions and the selected specification matter.

  • A clear agreement

    Discuss attendance, assessment, labour, parts and any travel costs.

Understand the parts working together

One door. Several possible causes.

The handle, cylinder, gearbox, locking strip and frame all contribute to the way a uPVC or composite door operates.

How the door meets the frame

Catching edges, visible rubbing and a change in the gap around the door are useful observations. The assessment considers the door fit alongside the locking mechanism, especially when operation changes as the door closes.

How the mechanism moves

The handle and key do different jobs within a multipoint arrangement. Explain which movement stops first and whether the locking points respond; do not force them to complete the sequence.

Which replacement is compatible

Multipoint parts are not interchangeable by appearance alone. Existing dimensions, markings and the complete mechanism guide the choice of suitable components if replacement is needed.

The handover

Check the whole locking sequence.

The useful outcome is a door that closes and operates correctly as an entrance, with the agreed fault addressed.

  • Check that the door closes without pulling or lifting it unusually.
  • Try the handle and key in the normal locking sequence.
  • Understand whether the work involved alignment, mechanism parts or the cylinder.

Useful answers about upvc door lock repairs.

Do I need a new door?

Not necessarily. A fault may concern the cylinder, gearbox, mechanism or alignment. The door needs assessing before that decision can be made.

Can the gearbox be replaced?

That depends on the mechanism, compatible parts and the confirmed scope of work. Ask about suitability when describing your door.

What about composite doors?

Describe the composite door and symptoms so suitable lock work can be discussed.

Do you offer general glazing repairs?

General glazing, hinge and wider door repairs are not advertised. Ask about the locking problem and confirm the scope before booking.
