Composite Door Lock Repairs

What Makes Composite Doors Different

Composite doors are the most popular front door type installed in the UK over the past 20 years — a timber core bonded with GRP (glass reinforced plastic) skin and a foam insulation fill. They’re heavy (typically 45–55kg), thermally stable by design, and they use multipoint locking systems almost identical to uPVC doors. They’re also the most frequently targeted door type for lock snapping — more on that below.

Broken Gearbox — Handle Spinning or Won’t Lift

If the handle spins freely with no resistance, or lifts but nothing happens along the door edge, the central gearbox has failed. This is the single most common composite door fault — the mechanism wears out through daily use and eventually shatters internally, often with an audible crack.

Don’t force it. Forcing a failed composite door gearbox can jam the locking hooks in the locked position, turning a straightforward gearbox swap into a full non-destructive entry job.

We open the door carefully, replace the broken gearbox with a matching part from our van stock, and test the full locking cycle before we leave. Most gearbox swaps take under an hour.

Price: from £99 + parts. Time: under 1 hour.

Dropped Door — Won’t Lock Without Forcing

Composite doors are heavy, and hinge wear is inevitable. A dropped door misaligns the hooks and rollers with the keeps on the frame, so the handle has to be forced or the door slammed to engage the lock. This puts enormous stress on the gearbox — left unfixed, it destroys it.

We realign the door using the hinge adjustment screws (composite hinges have 3-axis adjustment for exactly this reason), reset the keeps, and test the full lock. Usually the cheapest fix on our list and one of the most satisfying — the difference between “forcing the door every single day” and “one finger to lock it.”

Price: from £49. Time: 20–40 minutes.

Composite Door Cylinder Upgrade — Snap Attack Prevention

This is the most important security upgrade for any composite door, and the most overlooked.

Lock snapping is the primary method used by UK burglars on composite and uPVC doors. A standard Euro cylinder can be broken off using tools available in any DIY store in under 30 seconds — the cylinder snaps at its narrowest point, exposing the internal mechanism and allowing the door to be opened. In areas across Birmingham and the West Midlands, snap attacks account for a significant proportion of domestic burglaries.

The solution is a 3-star TS007 anti-snap cylinder — engineered so that any snap attempt sacrifices the outer sacrificial section while the inner security portion remains intact and the door stays locked. Brands we carry: Avocet ABS, Brisant Ultion, Mul-T-Lock MT5+. All are TS007 3-star rated and satisfy the cylinder requirements of virtually every UK home insurance policy.

If your composite door still has the standard cylinder it came with from the builder or installer, upgrading it is the single highest-value security improvement you can make.

Price: from £69 + parts as a standalone upgrade; from £49 + parts when added to any other visit.

Composite Door Multipoint Mechanism Failure

Where the gearbox has failed beyond driving the strip, or where the locking strip itself is physically damaged (hooks bent, rollers shattered), the full multipoint mechanism needs replacing. We carry full-length composite door locking strips and can retrofit modern equivalents where the original brand is discontinued.

Price: from £149 + parts. Time: 1–2 hours.

Wooden & Timber Door Lock Repairs

The Difference Between Timber Door Lock Types

Most timber front doors use one or two of the following: a mortice deadlock set into the body of the door, a rim nightlatch (Yale-type) on the surface, or both. Understanding which you have matters because the repairs are different.

Mortice Deadlock (BS3621) — Key Turns But Nothing Happens

A mortice deadlock is set into a pocket in the door edge. If the key turns but the bolt doesn’t move, or the key won’t turn at all, the internal mechanism is worn or seized. We open the door using non-destructive techniques, extract the lock case, and fit a replacement — almost always a British Standard BS3621 5-lever mortice lock, which is the standard required by most household insurance policies for final-exit timber doors.

Fitting a non-BS3621 lock on a timber front door can invalidate your home insurance — we never install anything below this standard.

Price: from £99 + parts. Time: 30–60 minutes.

Rim Nightlatch (Yale-Type) — Locked Out or Latch Faulty

The rim nightlatch sits on the surface of the door and latches automatically when the door closes — which is why it’s responsible for a large proportion of domestic lockouts (door slammed behind you, key inside). We open Yale-type doors non-destructively using specialist bypass and letterbox tools, then replace the cylinder, latch, or both if faulty.

Price: from £49 + parts. Time: under 30 minutes for entry; cylinder replacement a further 20 minutes.

Stiff or Swollen Timber Door

Wood absorbs moisture in autumn and winter, swelling against the frame and putting severe stress on the lock when the key is turned. If you’re forcing the key every day, stop — that’s how keys snap in the lock. We adjust the keeps, service the lock mechanism, and where the door has swollen significantly we plane the binding edge to restore a clean close.

Price: from £49. Time: 20–45 minutes depending on extent.

Period and Non-Standard Timber Doors

Older Victorian, Edwardian and period properties across Birmingham and the South West (particularly in Bath, Cheltenham and Bristol) often have non-standard mortice sizes, unusual backsets, or original hardware that standard replacements don’t fit. We carry a wide range of mortice sizes and can source non-standard cases — call and describe the door or send a photo to WhatsApp for a same-day diagnosis.

Frequently Asked Questions

My composite door won’t lock — what’s wrong? The two most common causes are a failed gearbox (if the handle spins or flops) or a dropped door putting the hooks out of alignment with the keeps (if you have to force or slam the door). Both are same-day repairs from £49. Send a WhatsApp photo of the door edge and handle for an instant diagnosis.

How much does it cost to repair a composite door lock? A hinge realignment costs from £49. A gearbox replacement costs from £99 plus parts. A full multipoint strip replacement costs from £149 plus parts. All prices are fixed and quoted before we travel — no call-out fee.

My composite door has been snapped — what do I do? If a burglar has snapped the cylinder and forced your door, call us immediately for same-day boarding up and a new anti-snap cylinder. We also carry out frame repair and door realignment following forced entry. A full written invoice is provided for your insurance claim.

Do I need to upgrade my composite door cylinder? If your composite door still has the original standard cylinder from when it was installed, yes — almost certainly. Standard Euro cylinders can be snapped in under 30 seconds with widely available tools. A 3-star TS007 anti-snap upgrade costs from £69 plus parts, takes under 20 minutes, and is the most effective security improvement you can make to a composite door.

What lock does my timber front door need for home insurance? Most UK home insurance policies require a British Standard BS3621 5-lever mortice lock on final-exit timber doors. Non-BS locks can reduce or void your claim after a burglary. We fit BS3621 as standard on every timber door job — no exceptions.

Can you open a wooden door without damaging it? Yes, in almost every case. For rim nightlatches (Yale-type) we use letterbox tools and slim-jim bypass techniques that leave no mark. For mortice locks we use picks and impressioning. Drilling is a last resort, and we always tell you before we reach for it.

My old Victorian timber door has a non-standard lock — can you still help? Yes. Period properties across Birmingham and the South West frequently have unusual mortice sizes, deep backsets, or original hardware that stock replacements won’t fit. We carry a wide range of sizes and can source non-standard cases. Send us a photo and we’ll confirm before attending.

Do you cover the South West and Home Counties as well as Birmingham? Yes — full coverage across Bath, Bristol, Swindon, Cheltenham, Gloucester, Luton, Milton Keynes, St Albans and Telford, as well as all of the West Midlands. See all areas →
