CALL FOR IMMEDIATE HELPHow Our uPVC Door Lock Repair & Mechanism Replacement Works
Simple, transparent process — we keep you informed every step of the way.
Tell us what's happening when you call — door won't lock, handle is stiff, key turns but nothing happens, door won't close properly. The more detail you give us, the better prepared your locksmith can be.
Your locksmith arrives and runs through a full diagnostic of the door — checking alignment, the multipoint mechanism, the cylinder, the handle spindle, and the keep plates on the frame.
Many uPVC lock problems are actually caused by the door dropping slightly out of alignment over time. Where that's the case, adjustment alone often solves the problem without any parts replacement at all.
Where a part genuinely needs replacing — a gearbox, a cylinder, a handle set, or a keep plate — we carry a wide stock on the van and can swap it out on the spot.
After the repair, we run the door through multiple lock-unlock cycles and check it seals and latches correctly before we leave. You get a 12-month guarantee on all parts and labour.

FAQs — uPVC Door Lock Repair & Mechanism Replacement
Straight answers to the questions we hear most often.
A mechanism adjustment starts from £79. If a gearbox or other component needs replacing, a full mechanism replacement starts from £89. We confirm the exact price once your locksmith has diagnosed the fault — and if it turns out to be a simple alignment issue, we charge accordingly, not the higher rate.
Often it is. A stiff handle on a uPVC door usually means the multipoint mechanism is struggling to operate, either because the door is out of alignment, the gearbox is starting to fail, or the cylinder is worn. It is worth getting it looked at before it stops working entirely.
In most cases, yes. We carry a wide range of gearboxes, cylinders, handles, and keep plates on every van. If you have an unusual door brand or a very old mechanism, there is a small chance we may need to order a part, but we will let you know when you call.
A straightforward alignment fix or cylinder swap typically takes 30–45 minutes. A full gearbox replacement usually takes under an hour. We aim to complete every job in a single visit.
Yes — all parts and workmanship are covered by our 12-month guarantee. If the repaired lock fails within that period due to our work or the parts we fitted, we will return and fix it at no cost to you.
