Common lock & handle problems we fix

  • Multipoint lock hooks or rollers no longer catch the keeps
  • Window handle snapped, stiff or won't close fully
  • Key turns but the door still opens — or the key won't turn at all
  • Door handle drops, feels loose or won't lift to engage the lock
  • Lost keys or moving house — cylinder needs changing

How a lock repair works

  1. 1. Diagnose

    We find whether the fault is the cylinder, gearbox, full multipoint strip or door alignment.

  2. 2. Replace

    Worn parts are swapped with matched hardware — including anti-snap cylinders if you want an upgrade.

  3. 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.

Why it breaks: what our engineers find in Northampton

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.

Seasonal swelling

uPVC and composite doors expand in hot weather. A door that locks fine in winter can become tight in summer and stress the lock.

Door dropping out of line

When hinges wear, the door sags and the locking hooks no longer meet the keeps. Forcing the handle up then strains the gearbox until it breaks.
