House & Home
Home security for the flats, mews houses and period terraces across Knightsbridge, Belgravia and South Kensington — matched to what your buildings insurer actually requires.
Keys & Lockouts
Lost Keys
A lost key with your address attached is effectively a spare front-door key in someone else's pocket. We rekey or replace the cylinder the same day.
Locked Out
Keys inside, door slammed shut, or a key that turns but won't throw the bolt. Opened non-destructively in most cases.
Broken Keys
Free, no-obligation extraction for keys that have cracked or sheared in the lock, followed by a fresh cut.
Broken & Snapped Keys
Half the key still in the cylinder, half in your hand. Removed with the right extraction tools rather than force.
Lock Repair & Replacement
Broken Locks
A broken lock leaves a property exposed the moment it fails. We secure it first, then repair or replace it properly.
Jammed Locks
A key that won't turn either way is rarely the lock itself — often a dropped door or misaligned keep.
Lock Change
Moving into a flat where you don't know how many keys exist, or a tenancy ending — we'll tell you honestly whether a rekey covers it.
Lock Replacement
Euro cylinders, mortice cases and uPVC gearboxes measured before fitting, not guessed on site.
Lock Installation
New locks fitted to timber, composite and period doors, including mortising a fresh case into a door that's never had a deadlock.
Locks Repair
Mechanisms that stick, drag or need force to turn — diagnosed on site before we recommend a full replacement.
Door Lock Fitting
Supply-and-fit for a single new lock, matched to your door thickness and existing hardware before we cut anything.
Doors & Windows
UPVC Door Lock
Multipoint mechanisms, stripped gearboxes and dropped doors. When the key turns but the door won't lock, the cylinder is rarely the problem.
Window Locks
Ground and lower-floor window locks fitted and repaired — common on the converted mansion flats around Ovington Gardens.
Patio Doors
Sliding-door locks and multipoint patio mechanisms serviced and replaced — a common weak point on rear extensions.
Bi-Folding Doors
Locking gear on bi-fold sets adjusted, repaired or replaced so every panel locks properly, not just the master leaf.
UPVC Specialist
Deeper uPVC diagnostics — gearbox replacement, door alignment and hinge adjustment beyond a straightforward lock swap.
Smart, Safe & Moving Home
Smart Locks
Keypad, app-controlled and biometric locks fitted, with a mechanical override kept so a flat battery never locks you out.
Safe Locks
Safes opened, serviced and fitted — lost combinations and failed electronic locks handled without damaging the safe.
Safe Specialist
Higher-spec domestic and small commercial safes — supply, installation and anchoring done properly, not left loose in a cupboard.
Moving Home
A full lock change for every external door on completion day, so no previous keyholder still has access.
Emergency Locksmith
The calls that can't wait. Our overnight rota is built for Knightsbridge's mix of mansion blocks, embassies and Georgian terraces, not a national call centre.
24 Hour Locksmith
A genuine overnight rota across SW1, SW3 and SW7, including mansion block porters and communal doors.
Emergency 24 Hour Locksmith
Genuine emergencies triaged first — a door that won't secure, stolen keys with an address attached, or a vulnerable resident shut out.
Emergency Locksmith (24/7)
Round-the-clock cover including Christmas and every bank holiday, with the out-of-hours rate agreed before anyone travels.
Fast Locksmith
Working from Montpelier Street puts Sloane Street, Beauchamp Place and Hyde Park Corner minutes away rather than across the city.
Locksmith Near Me
Honest arrival times by postcode from a real Knightsbridge address, rather than a national listing ranking from another city.
Commercial
Shopfronts, offices and hospitality premises around Knightsbridge and Brompton Road, kept trading with minimal disruption.
Commercial Locksmith
Shopfronts, offices and hospitality premises around Knightsbridge, including out-of-hours cover for retail units.
Key-Alike Systems
One key across multiple doors, or a tiered access system for a managing agent handling several units in one block.
Security Systems
Beyond the lock — the wider security fit-out that mansion blocks and commercial units in SW1 increasingly ask for.
CCTV Installation
Cameras positioned to actually cover entry points and blind spots, not just mounted wherever the cabling is easiest.
Intercom Systems
Video and audio door entry for mansion blocks and private houses, wired in or upgraded from an existing panel.
Security Grilles
Shutters and grilles for shopfronts and ground-floor units, fitted to lock securely without blocking fire escape routes.

An honest number rather than an optimistic one if you're further out across London.
Locksmith Services — Frequently Asked Questions
Which service do I need if I'm locked out right now?
Start with the Locked Out page, or simply call or WhatsApp us. A slipped latch, a deadlocked front door and a seized uPVC multipoint gearbox are three different jobs — thirty seconds on the phone tells us which one you have.
Do you cover all of Knightsbridge and Belgravia?
Yes — our core coverage is SW1A, SW1E, SW1H, SW1P, SW1V, SW1W, SW1X, SW1Y, SW3 and SW7, worked from 4 Montpelier Street.
How much does a locksmith cost in Knightsbridge?
We quote per job rather than publishing a price list. Describe the door on the phone or WhatsApp and you'll have the price before we travel.
Will you damage my door to get in?
Rarely. Most lockouts are opened by picking or bypass, leaving the door and existing cylinder working exactly as before.
Can I message you on WhatsApp instead of calling?
Yes — tap the WhatsApp button above to message us directly on 020 8261 7495. It's often quicker for sending a photo of the lock or door.
Do you work with managing agents and porters in mansion blocks?
Regularly. Communal door entry, tenancy changeovers, key-alike suites and lock changes between lets — we can invoice on account.
How do I book?
Call 020 8534 4949 or WhatsApp 020 8261 7495, day or night. Describe the door, get the price, and we'll give you a realistic arrival window.
Not Sure Which Service You Need?
Describe the door and what's happened. We'll tell you which job it is, what it costs and how long we'll be.
