Locked out or unable to secure the door?

A straightforward service with no call centre in the middle
You deal with the locksmith who will attend and carry out the work.
Explain the problem
Tell Jon what the door, lock or key is doing. Photographs can help identify the likely fault.
Get clear options
After inspection, Jon explains whether adjustment, repair or replacement is the sensible route.
Repair and test
The work is completed using suitable parts, then the door and lock are tested before completion.
Real jobs, not generic promises
These examples show why inspecting the complete door and locking system matters.
uPVC door gearbox repair
A faulty multipoint gearbox was removed from a uPVC door after the operating problem was traced inside the locking system. The replacement component was fitted and the handles, locking points and door operation were checked before the job was completed.

Snapped key assessed at the door
A key had snapped inside the cylinder at a Stevenage property. The door, key fragment and lock were assessed before deciding on the safest extraction method. After the obstruction was removed, the lock was checked to establish whether it remained serviceable.
Discuss a broken-key problemSpinning key and incorrect cylinder size
Jon found a worn, incorrectly sized cylinder rather than a failed gearbox. A correctly sized Ultion 1 Star Plus cylinder was fitted, the top hinge adjusted and the door tested.
Internal door opened after latch failure
A failed latch prevented an internal door from opening at a Stevenage rental property. Jon opened the door and identified the latch without recommending unnecessary main-lock replacement.
Professional standards backed by independent checks

Common door and lock problems Jon investigates
Key will not turn
The cause may be the cylinder, worn internal parts or pressure created by poor door alignment.
Handle feels stiff
A dropped door, tight keeps or gearbox strain can make the handle progressively harder to lift.
Door will not lock
The full mechanism, keeps, handles and alignment are checked before parts are recommended.
Moved into a property
Changing or upgrading the locks prevents old or unknown keys from continuing to provide access.
Break-in damage
The damaged lock, cylinder, handles, door and frame are assessed so the property can be secured.
Business entrance fault
Commercial doors are assessed with disruption kept to a minimum wherever possible.
Repair the cause, not only the symptom
Replacing a cylinder will not correct a dropped door, and fitting new handles will not solve a strained gearbox. Jon checks how the door closes, where the locking points meet the keeps and how the mechanism operates. This wider inspection helps identify the actual fault, protects new components from avoidable strain and gives you a clearer explanation of the work required.
Security upgrades suited to the existing door
If you have moved home, lost keys or want stronger protection, the existing door and hardware are checked before an upgrade is suggested. Options can include correctly sized anti-snap cylinders, British Standard locks and suitable security handles. The recommendation depends on the door construction, the current locking system and any relevant insurance requirements, not simply a brand name.
