About Gerry — Composite Door Locksmith for London
The Key Locksmith is run by me, Gerry Commane. I’m an independent MLA-approved locksmith based in Orpington, covering London, South East London, Bromley, Croydon, Lewisham, Greenwich, Bexley and nearby Kent areas.
Before becoming a locksmith, I served in the Royal Navy and later worked in the construction industry on major projects including Wembley Stadium and North Middlesex Hospital. That background helps with composite door repairs because the job often needs practical problem-solving, careful adjustment and a good understanding of how doors, locks, frames, hinges, cylinders and multipoint mechanisms work together.
I regularly repair composite and uPVC doors for homeowners, landlords, tenants, shops, offices and managed properties. When you call The Key Locksmith, you speak directly to Gerry, not a national call centre.
I’m MLA approved, an Auto Locksmiths Association member, DBS checked, fully insured, and fitted parts come with a 24-month parts and labour guarantee.

What Our Customers Say
⭐⭐⭐⭐⭐
"Not all heroes wear capes!! Thank you so much for your help today getting my car open after my son locked himself in there on the hottest day of the year. I was kept updated constantly which helped keep me calm and Gerry clearly got there as soon as traffic allowed for. Once at the car park he literally ran across it to my car to help me as quickly as he could. After unlocking the car in minutes he wouldn't even accept payment as a child was in the car. I couldn't have asked for anything more. Thank you so so much!"
— Kirsty McShane, Google Review
⭐⭐⭐⭐⭐
"I’m giving Gerry a 5-star review because he was truly amazing! He arrived exactly when he said he would, and his fees were both affordable and reasonable. He could have easily charged us more, but he didn’t, which I really appreciated. I wish more specialists had his integrity."
— Mayur & Ila Vashee, Google Review

"Gerry was very helpful and installed an upgraded replacement lock on my Ford Transit in Orpington very quickly after being damaged by an attempted theft. Highly recommended." Simon Porter, Google Review

Composite Door Repair Specialist in London
Composite doors are strong, secure and popular across London homes, flats, rental properties and commercial buildings. But when the lock, handles, hinges, keeps or multipoint mechanism start to fail, the door can quickly become stiff, unreliable or impossible to secure.
The Key Locksmith repairs common composite door problems across London, including:
Composite door will not lock
Composite door will not open
Door handle is stiff
Door handle is floppy
Key will not turn
Key turns but door will not unlock
Multipoint lock has failed
Gearbox has broken
Door is jammed shut
Door has dropped
Door is catching on the frame
Door only locks when lifted hard
Faulty euro cylinder
Broken handles
Misaligned keeps
Worn hinges
Failed locking strip
Door hard to close
Door not sealing properly
The aim is to get the door working smoothly, locking properly and secure again without replacing unnecessary parts.
A Common Composite Door Repair Job in London
A typical composite door repair call is a customer whose front door has become harder to lock over time. The handle may need lifting higher each week, the key may feel tight, or the door may only lock if it is pulled firmly into the frame.
Eventually, the gearbox or multipoint mechanism can fail completely. The door may jam shut, the handle may go floppy, or the key may stop turning.
On jobs like this, I check the full door setup, not just the lock. The problem may be caused by door alignment, hinge movement, worn keeps, a failing gearbox, a damaged cylinder, stiff handles or pressure on the locking strip.
Where possible, I adjust and repair the door before replacing parts. If the gearbox or mechanism has failed, I explain the options clearly and fit a suitable replacement so the door locks properly again.
The aim is to fix the cause of the problem, not just make the door work for a few days.
Composite Door Will Not Lock
One of the most common problems is a composite door that will not lock. You may be able to close the door, but the handle will not lift fully, the hooks will not engage, or the key will not turn.
This can be caused by:
Door misalignment
Dropped hinges
Keeps out of position
A worn gearbox
A failing multipoint mechanism
A faulty euro cylinder
Stiff handles
Pressure on the locking strip
Door swelling or movement
Weather-related expansion
Forcing the handle or key can make the problem worse. If the door has become stiff or unreliable, it is usually better to have it checked before the mechanism fails completely.
I can diagnose the fault, adjust the door where possible, replace failed parts where needed, and leave the door locking smoothly again.
Composite Door Will Not Open
A composite door that will not open can be stressful, especially if it is your main front door or the only practical entrance to the property.
The key may turn but nothing happens, the handle may move without releasing the door, or the door may be jammed shut because the multipoint lock has failed.
I can help with:
Jammed composite doors
Failed gearboxes
Broken multipoint locks
Faulty euro cylinders
Handles not operating the lock
Hooks, rollers or bolts stuck in the frame
Doors stuck locked shut
Keys spinning in the cylinder
Composite doors that will not release from the frame
Where possible, I open the door carefully and repair the fault without unnecessary damage. If the mechanism has failed, I can replace the gearbox or locking strip where suitable.
Composite Door Multipoint Lock Repairs London
Most composite doors use a multipoint locking system. This usually includes a central gearbox connected to hooks, rollers, deadbolts or shootbolts that secure the door into the frame.
When the multipoint lock fails, the door may become difficult to lock, difficult to unlock, or completely jammed.
I repair and replace common composite door multipoint lock parts including:
Gearboxes
Full multipoint mechanisms
Hooks
Rollers
Deadbolts
Shootbolts
Keeps
Handles
Euro cylinders
Door alignment faults
I work with many common UK multipoint lock brands, including ERA, Yale, GU, Winkhaus, Lockmaster, Avocet, Millenco, Fuhr, Fullex and others.
Composite Door Gearbox Replacement London
The gearbox is the central part of the multipoint lock. It is the section operated by the handle and key. When it fails, the door may not lock, unlock or open properly.
Signs of a failing gearbox include:
Handle feels stiff
Handle drops or goes floppy
Key will not turn fully
Door only locks when lifted hard
Door unlocks sometimes but not always
Mechanism feels rough
Door has jammed shut
Hooks or bolts do not move properly
In many cases, the full multipoint locking strip does not need replacing. If the gearbox is available and suitable, I can replace the failed gearbox and realign the door so the new part is not put under unnecessary strain.
Composite Door Alignment and Adjustment
Many composite door lock problems are caused by poor alignment. Over time, the door can move slightly, hinges can settle, or the frame keeps can become misaligned.
This puts pressure on the locking mechanism. The handle becomes harder to lift, the key becomes tight, and eventually the gearbox may fail.
I can adjust composite doors where possible, including:
Hinge adjustment
Keep adjustment
Door alignment
Reducing pressure on the lock
Checking handle operation
Checking the cylinder
Testing the multipoint mechanism
Checking whether the door is catching or binding
A proper adjustment can often prevent a more expensive failure later.
Composite Door Handle Repairs
Faulty composite door handles can make the door difficult or unsafe to use. Handles may become loose, stiff, floppy, cracked or completely broken.
I can replace composite door handles and check whether the handle has failed on its own or whether another fault has caused it.
Common handle problems include:
Loose handles
Floppy handles
Broken springs
Handles not lifting fully
Handles not returning
Stiff operation
Worn screws
Damaged backplates
Handles strained by a misaligned door
If the handle is stiff because the door is misaligned or the gearbox is failing, I will explain that before replacing parts.
Composite Door Cylinder Replacement
The euro cylinder is the part where the key goes. If the cylinder is worn, damaged or faulty, the key may become hard to turn, stick, spin or fail completely.
I can replace composite door cylinders for:
Lost keys
Stolen keys
Faulty cylinders
Keys hard to turn
Keys snapped in lock
Security upgrades
Moving home
Tenant changes
Landlord lock changes
Burglary repairs
Where suitable, I can fit higher-security cylinders designed to improve protection against snapping, drilling and picking.
Composite Door Repairs After a Break-In
If your composite door has been damaged during a burglary or attempted break-in, I can help secure the property and advise on practical repairs or upgrades.
This may include:
Replacing damaged cylinders
Replacing broken handles
Repairing or replacing keeps
Checking the multipoint lock
Adjusting the door
Fitting stronger cylinders
Improving door security
Emergency securing
Checking for forced-entry damage
After a break-in, I will explain the weak point and give honest advice on what will make the door more secure.

End-of-tenancy lock changes

Communal door issues
Rental property security

Composite Door Repairs for Shops, Offices and Commercial Properties

I can help with:
Commercial composite door repairs
Office composite doors
Staff entrance locks
Commercial lock changes
Failed multipoint locks
Faulty handles
Emergency securing
Door alignment issues
High-security cylinder upgrades
Burglary damage repairs
For commercial properties, the aim is to get the door secure and working properly with as little disruption as possible.
Composite and uPVC Door Repairs
Composite doors and uPVC doors often use similar multipoint locking systems, gearboxes, handles and euro cylinders. I repair both composite and uPVC door lock problems across London.
If you are not sure whether your door is composite or uPVC, that is not a problem. I can diagnose the fault, identify the lock type, check the mechanism and explain what repair is needed.
Common shared faults include failed gearboxes, stiff handles, faulty cylinders, jammed doors, dropped doors, misaligned keeps and doors that will not lock properly.
Why MLA Approval Matters
When a composite door will not open or lock, it is easy to call the first cheap advert you see. The problem is that some national call centre locksmith adverts use low starting prices and then send unknown subcontractors who may charge much more once they arrive.
The Key Locksmith is different. I’m MLA approved, independent and accountable for my own work. You speak directly to me, get clear advice, and know who is coming to your door.
Choosing an MLA-approved locksmith gives extra reassurance that the person working on your door has been vetted and works to recognised professional standards.
