Common Lock Problems We Can Repair:
Locks contain several components that must work together correctly. Over time, wear, misalignment, damaged parts and general deterioration can cause problems with their operation.
Some of the most common lock faults we repair include:
- Locks that won’t lock or unlock – faulty components or alignment problems can prevent the lock from operating correctly.
- Jammed or stuck locks – internal wear, damaged mechanisms or obstructions can cause locks to seize.
- Keys that won’t turn – problems with the cylinder, internal components or door alignment can prevent the key from rotating.
- Keys that turn without unlocking – worn or damaged internal components can prevent the locking mechanism from engaging.
- Stiff or difficult locks – increased resistance can indicate wear, misalignment or problems within the mechanism.
- Misaligned door locks – dropped doors or movement within the frame can prevent locking points from engaging properly.
- Faulty multipoint locking mechanisms – problems with gearboxes, hooks, rollers or locking points can affect uPVC and composite doors.
- Damaged lock cylinders – worn or damaged cylinders can cause unreliable locking and unlocking.
- Broken or damaged keys – damaged keys can affect operation, while broken keys may become trapped inside the lock.
- Burglary or attempted break-in damage – forced entry can damage cylinders, locking mechanisms and surrounding hardware.
- Locks that only work intermittently – developing faults can cause locks to operate inconsistently before failing completely.
- General wear and tear – regular use can eventually affect the reliability of internal locking components.
Not every faulty lock needs replacing. In some cases, adjusting the door, realigning the locking points or repairing an individual component may resolve the problem. However, where a lock is badly worn, damaged or no longer provides adequate security, replacement may be the more appropriate option.

Frequently Asked Questions - FAQs
Can a faulty door lock be repaired without replacing it?
Yes, in many cases. Problems caused by misalignment, sticking components or certain mechanical faults can sometimes be resolved through adjustments or targeted repairs. However, badly worn or damaged locks may require replacement to restore reliable security.
Why won't my key turn in the lock?
A key that won't turn can indicate several problems, including a faulty cylinder, internal wear, damaged components or misalignment between the door and frame. Avoid forcing the key, as this could cause further damage or leave it broken inside the lock.
