uPVC Lock Services

uPVC doors and windows are found in millions of London homes and businesses. While durable and energy-efficient, their locking mechanisms can wear out over time, leaving your property vulnerable. Our specialist uPVC locksmiths carry the parts and expertise to repair or replace any uPVC lock quickly and effectively. Need a full lock replacement? See our lock change service.

Euro Cylinder Replacement

Replace old, worn, or insecure euro cylinders with modern anti-snap, anti-bump, anti-pick, and anti-drill cylinders. We carry a range of sizes and finishes to match your door hardware. A quick and affordable security upgrade.

From £69 (labour)

Multi-Point Lock Mechanism

Repair or replacement of the full multi-point locking gearbox. If your door handle feels stiff, the key will not turn fully, or the locking points no longer engage, the gearbox likely needs replacing. We stock mechanisms for all major uPVC door brands.

uPVC Door Handle Replacement

Broken, loose, or stiff door handles replaced with new matching hardware. We carry a range of lever/lever and lever/pad handles in various finishes including white, chrome, gold, and black.

uPVC Window Lock Repair

Window locks, handles, and restrictors repaired or replaced. We service espagnolette handles, cockspur handles, and multi-point window locks on all uPVC window types including casement, tilt-and-turn, and sash. Learn more about window lock types.

uPVC Door Realignment

If your uPVC door has dropped, sticks, or will not close properly, we adjust the hinges and strike plates to realign it. This restores smooth operation and ensures the multi-point locks engage fully.

Troubleshooting

Common uPVC Door Problems

Door Won't Lock

Usually caused by a worn gearbox, misaligned door, or faulty cylinder. Our locksmith diagnoses the exact cause and fixes it on the spot.

Stiff Handle

A stiff or hard-to-operate handle often indicates a failing gearbox or internal mechanism. Replacing the handle alone may not fix the underlying issue.

Key Won't Turn

This can be caused by a worn cylinder, misaligned door, or internal gearbox fault. Attempting to force the key can break it inside the lock.

Draughts Around Door

If your door no longer seals properly, the hinges or keep may need adjusting. Proper alignment restores the seal and improves energy efficiency.

uPVC Locksmith FAQ

Find answers to common questions about our locksmith services.

Can you repair a uPVC door that won't lock properly?
Yes, this is one of the most common uPVC door problems we resolve. Causes include a dropped door, misaligned strikers, worn gearbox, or a faulty euro cylinder. Our locksmith will diagnose the exact issue and carry out the repair on-site.
How much does a uPVC door lock replacement cost?
Euro cylinder replacement typically costs from £69 (labour) plus the cost of the cylinder. Full multi-point gearbox replacement costs more depending on the mechanism type. We provide a clear quote after assessing your door.
What is an anti-snap euro cylinder?
An anti-snap euro cylinder is designed to resist a common break-in technique where thieves snap the cylinder in half to access the locking mechanism. Anti-snap cylinders have a built-in break point that, when snapped, leaves the internal mechanism intact and the door locked.
My uPVC door has dropped - can you fix it?
Yes, door dropping is very common with uPVC doors. We adjust the hinges to realign the door so it closes and locks correctly again. If the hinges are worn beyond adjustment, we replace them with new ones.
Do you repair uPVC window locks too?
Yes, we repair and replace all types of uPVC window locks including espagnolette handles, window restrictors, and multi-point window locks. We carry a range of handles and mechanisms suitable for most uPVC window brands.
