UPVC Door Locks Brighton — Repairs, Replacements & Mechanism Servicing by City Locksmith Brighton

If your UPVC or composite door lock isn’t working properly, sticks when you lift the handle, or won’t lock at all — you’re not alone.
At City Locksmith Brighton, Alex and his team specialise in repairing, replacing, and servicing UPVC and composite door locks across Brighton and Hove.

We work with all major UK lock and multipoint mechanism brands — including Yale, ERA, GU, Avocet, Winkhaus, Mila, Maco, Fuhr, Lockmaster, Safeware, Roto, and Fullex — to get your door working like new again.

Common UPVC and Composite Door Lock Problems We Fix

Jammed or Stiff Locking Mechanisms

If your door handle is stiff or jammed, it’s usually a sign that the multipoint locking mechanism has worn or is misaligned. This is common with Yale, GU, and Mila locks after years of use.
We can repair or replace the centre gearbox or full strip mechanism on-site — often without replacing the entire lock.

Door Won’t Lock or Unlock

When a uPVC or composite door won’t lock, it’s often due to the euro cylinder failing or the hooks and rollers in the mechanism not aligning properly.
Alex can assess whether it’s a faulty ERA or Avocet cylinder, a broken cam, or just a misaligned door — and fix it the same day.

Snapped or Spinning Handle

A loose or spinning handle is often caused by wear in the Fuhr, Winkhaus, or Lockmaster mechanism. We carry replacement handles and full gearboxes for all major brands and can fit them without damaging your door.

Lost Keys or Key Won’t Turn

If your key won’t turn or has snapped in the lock, we can extract the broken key, fit a new euro cylinder, and cut new keys on-site.
We stock anti-snap, anti-pick, and anti-drill cylinders from trusted names like Yale, ABS, Ultion, ERA, and Avocet — all compliant with British Standard TS007 and insurance requirements.

Misaligned or Warped Doors

If your plastic or composite door is hard to close, drags on the frame, or needs lifting to lock, the hinges or strike plates are likely out of alignment.
We can realign and adjust your door, lubricate the locking points, and make sure the mechanism engages smoothly again — preventing further damage to the multi-point lock strip.
