Expert UPVC Door Lock Solutions for Homes & Businesses
At KBO Lock & Safe, we specialize in UPVC door lock repairs, adjustments, and full multipoint lock replacements. If you are experiencing issues such as stiff handles, floppy handles, difficulty turning the key, or doors not locking properly, we have the expertise to restore your door’s security and functionality.

Common UPVC Door Lock Issues We Fix
- Stiff or Difficult-to-Turn Key – Often caused by worn or misaligned components.
- Floppy or Loose Handles – Usually due to internal wear or a failing gearbox.
- Door Not Locking Properly – A misaligned door or faulty mechanism can prevent the multipoint system from engaging.
- Handles Difficult to Lift – May indicate a problem with the multipoint locking system or door alignment.
- Lock Jamming or Failing Completely – A sign that the gearbox or mechanism needs repair or replacement.
UPVC Door Lock Adjustments
Over time, UPVC doors can become misaligned, making it difficult to lock or unlock the door. Our adjustment service ensures smooth operation, prolonging the life of your lock and preventing unnecessary replacements.
Multipoint Lock Replacements
If your multipoint locking system is beyond repair, we can replace it with a high-quality, secure alternative. We stock and install all major brands of multipoint locks, ensuring compatibility with your door.
Gearbox Replacements
The gearbox is the heart of the locking mechanism. If it fails, your door may jam, stop locking, or refuse to open. We can replace damaged gearboxes, restoring full function to your door without the need for a full lock replacement.
