What this actually involves

UPVC door locks fail in predictable ways. Here’s what’s actually wrong with yours.

UPVC multipoint door systems are more complex than a single cylinder lock — they have a central gearbox, shoot bolts, hooks, rollers and a cylinder, all working together. When something goes wrong, the symptoms vary a lot: the handle drops and won’t lift, the door won’t lock from the outside, it locks but won’t open again, or the key turns but nothing engages. Each symptom points to a different fault.

The most common failure is the gearbox. These are plastic-and-metal mechanisms that see thousands of cycles over their lifespan, and eventually they wear out. The good news is that the gearbox is usually replaceable without touching the cylinder or the door frame — we carry Maco, Fuhr, Yale, ERA and Fullex gearboxes as van stock and can swap most in 45-90 minutes.

The second most common issue is a misaligned or dropped door. A UPVC door that’s sagged on its hinges won’t engage its keep correctly, which puts enormous strain on the mechanism and eventually kills the gearbox. If we see this, we’ll also adjust the hinges and door alignment — fixing just the gearbox on a misaligned door is a temporary fix at best.

Cylinders are the third common issue. Standard euro cylinders on UPVC doors are vulnerable to snapping — a known attack method. If yours is more than a few years old and isn’t TS007 rated, an upgrade makes sense at the same time as any other repair.

Why customers choose us

  • Gearbox stock on the van

    Maco, Fuhr, Yale, ERA, Fullex — we carry the most common UPVC gearboxes. Most repairs are completed in a single visit.

  • Door alignment check included

    If the door is dropping, we fix that too. A new gearbox on a misaligned door will fail again within months.

  • Full diagnosis before quoting

    We identify the actual fault before recommending a fix. You won’t pay for parts you don’t need.

  • Cylinder upgrade option

    If your current cylinder isn’t anti-snap rated, we can upgrade at the same visit for a small additional cost.

  • 12-month warranty

    On all parts and labour. Same fault within 12 months, we return free of charge.

Common questions

About upvc door lock.

Almost certainly the gearbox. When a multipoint gearbox wears out or fails, the handle loses its engagement and drops. The door may still be locked (the hook bolts and rollers may still be engaged) but the mechanism won't operate correctly. We carry gearbox replacements for most common UPVC door brands.

This usually means a faulty or worn cylinder, or a cylinder that's been slightly forced at some point. It can also be a gearbox issue where the outside lever isn't transmitting to the mechanism. We'll diagnose on site.

This can be the gearbox seizing, or a cylinder that's failed internally. It's also possible the door has warped slightly and the latch or hook bolt is binding against the keep. Call us — don't force the handle as you can strip the spindle.

Usually 45-90 minutes. We need to remove the door furniture, take out the old gearbox (which runs the full height of the door), fit the replacement and adjust it correctly. The door alignment check adds another 15-20 minutes.

UPVC doors typically carry a 10-year frame warranty and a shorter (5-7 year) mechanism warranty. If your door is relatively new and the mechanism has failed, the manufacturer or installer may cover it. If not, we're usually the cheaper option vs going back to the original company.

That's a keep or roller issue. The rollers and keep plate need to align correctly for the door to hold in wind. If the door has dropped slightly or the keep has shifted, the rollers miss. We can adjust this without replacing the full mechanism.

Technically yes, if you can identify the correct replacement gearbox and have experience with these mechanisms. In practice, getting the wrong size gearbox is common, and fitting it slightly out of adjustment will cause it to fail faster. Most people find it easier to have it done.
