How a lock repair works
1. Diagnose
We find whether the fault is the cylinder, gearbox, full multipoint strip or door alignment.
2. Replace
Worn parts are swapped with matched hardware — including anti-snap cylinders if you want an upgrade.
3. Test
We adjust keeps and test every locking point so the door opens and locks smoothly.
Most lock faults are fixed by replacing a single part, not the whole door — and we carry common gearboxes and cylinders on the van.
The real causes behind window & door lock repair jobs in Harpole
Worn gearbox
The gearbox inside a uPVC door turns every handle movement into lock movement. Thousands of uses later, its internal parts wear and slip.
Cheap or old cylinders
Older euro cylinders wear internally, so keys stick or won't turn — and many are vulnerable to lock snapping.
Lack of lubrication
Multipoint locks are rarely oiled. Dirt and dry moving parts make the mechanism stiff, which leads to snapped handles and seized keeps.
