Why customers bring uPVC faults to Armalock Locksmiths
More than the visible symptom

Full sequence tested
The door is checked through closing, locking and unlocking once work is complete.
Stiff door warning taken seriously
Acting early can prevent extra damage to a struggling multipoint setup.
Tracing the real cause of a uPVC door fault
A uPVC door can go wrong in ways that look simple from the outside but involve several linked parts. The handle may not lift, the key may not turn, the multipoint lock may fail to engage, or the door may jam before it closes properly. We assess the cylinder, gearbox, mechanism, keeps and alignment before deciding what the fault actually is. With Armalock Locksmiths, the goal is to repair the part that has failed without overlooking a door movement issue that could put the whole system under strain again.
Adjustment, repair or replacement based on what we find
Forcing a stiff uPVC mechanism can make the situation worse and may leave the door insecure. That is why we work through the full locking sequence and check how the door closes, engages and unlocks before recommending the right fix. Some faults need adjustment. Others need a specific component repaired or replaced. Armalock Locksmiths explains that difference clearly, then carries out final checks so the door returns to smooth use instead of feeling temporarily better for a short time.
Frequently asked questions
Why will my uPVC door handle not lift properly?
That symptom can come from more than one place. The issue may sit in the handle, the gearbox, the wider multipoint mechanism or in the alignment of the door itself. We assess the whole setup so the repair is based on the actual fault rather than on the first part that seems awkward.
Should I force a key that will not turn in a uPVC door?
No. Forcing a stiff key can worsen internal damage or leave the door stuck in a harder position to deal with. If the key or handle has become resistant, it is better to stop using force and have the door assessed before a partial fault turns into a full lockout or insecure entrance.
Can a uPVC door need adjustment instead of a new lock?
Yes. Some problems are caused by movement in the door or wear that affects alignment rather than complete failure of the lock itself. In those cases, adjustment or targeted component work may be the better route. We check the full locking action before deciding.
