Locksmith
Knightsbridge Locksmiths is a local, licensed locksmith based at 4 Montpelier Street, SW7 — lockouts, lock repairs and replacements, and 24/7 emergency call-outs, handled by our own engineers rather than a subcontractor network.
Not Every Locksmith Callout Is the Same Job
The fix depends entirely on what's gone wrong at the door. A slipped latch on a communal entrance is opened in minutes with a card or letterbox tool. A deadlocked door needs picking or a locksmith's key. A seized multipoint mechanism needs mechanism knowledge, not force. Telling a locksmith which one you've got means the right tools are already on the van before they arrive.
Slipped Latch
No key turned, just a door that swung shut. Opened with a card or letterbox tool — no drilling, nothing to replace.
Deadlock & Multipoint
Key turned an extra time, or a gearbox jammed mid-throw. Needs picking skill, not a harder pull on the handle.
Snapped Key
Half a key in the cylinder. Extracted with proper tools, then tested through a full cycle before we leave.
What a Locksmith Can Do For You
From an out-of-hours lockout to a full commercial access-control fit-out, one engineer sees the job through — quoted before we travel, itemised on the invoice after.
Lock Installation, Replacement and Security Upgrades
Whether it's a tired five-lever mortice on a period front door or a full digital access system for a commercial unit, we fit hardware to a named standard, not a guess. Every job is quoted against what your insurer, landlord or building manager actually requires.
Mortice locks & deadbolts
BS3621 five-lever mortices for timber doors — the standard most UK home insurance policies specify by name.
High-security cylinder upgrades
Anti-snap, anti-pick and anti-drill cylinders to TS007 3-star or Sold Secure Diamond, for doors that see daily wear.
Smart and digital locks
Keypad, fob and app-controlled locks fitted and set up properly — not just screwed on and left.
uPVC gearbox & multipoint repair
Seized handles and misaligned keeps are usually a gearbox or a dropped door, not the cylinder — we diagnose before we quote.
Built on Proof, Not Promises
Fully licensed and insured
There's no mandatory UK locksmith licence — anyone can print a van sticker. Our engineers show ID and carry full public liability cover.
Priced before we travel
Describe the door and fault on the phone and the figure quoted — out-of-hours rate included — is the one on the invoice.
Non-destructive entry first
Picking and bypass before drilling. Drilling is a last resort, and we always tell you before we reach for it.
Fast across Central London
Working from Montpelier Street puts Knightsbridge, Chelsea, Belgravia and South Kensington minutes away.
What Happens When You Call
- Describe the door, not just the fault
Timber or uPVC, one keyhole or two, does the handle lift — thirty seconds decides which engineer and parts we send.
- Get the price on the call
Quoted against what you've described, out-of-hours rate included, before anyone gets in the van.
- We open it, then secure it
Non-destructive methods first, then the repair or replacement, tested with you before we leave.
- The invoice names the parts
Make, model and standard of everything fitted — what your insurer or landlord will need.
Locksmith Coverage, Area by Area
The doors change street by street across Central London — here's how a locksmith job looks in four of the areas we cover most.
Locksmith Knightsbridge (SW7)
Period conversions around Beauchamp Place, private mews houses off Brompton Road, and newer composite doors near Montpelier Street — our engineers work this patch daily, so a diagnosis over the phone usually holds when we arrive. Residential lockouts, lock changes and genuine 24-hour emergency cover, all worked by our own team rather than a subcontractor.
Locksmith Chelsea & Belgravia (SW3 / SW1X)
King's Road retail units and the grand residential terraces around Eaton Square both fall inside our patch. Forced doors and broken locks are made secure the same visit, then repaired to BS3621 or TS007 3-star standard — the level most Chelsea and Belgravia insurance policies specify.
Locksmith South Kensington (SW7)
Dense with converted flats on original timber doors around Exhibition Road and Gloucester Road. A lost key with an address attached gets treated as a security job, not just an inconvenience — non-destructive entry first, then a fresh cylinder so the lost key stops working.
Locksmith Pimlico & Belgravia (SW1P / SW1E)
Older euro cylinders around Warwick Way and Eaton Square are prone to anti-snap failure. We extract the fragment with proper tools rather than pliers or superglue, test the lock through a full cycle, and flag a TS007 3-star upgrade if the cylinder was never protected.

FAQs — Locksmith
How much does a locksmith in London cost?
We quote per job, not from a price list — lock type, parts needed and time of day all affect it. You'll have the price before we travel, out-of-hours rate included.
Will you damage my door to get in?
Rarely. Most lockouts are opened by picking or bypass, leaving the existing cylinder working exactly as before. Drilling is a last resort, and we tell you first.
How fast can you reach me in Central London?
Typically within 30 minutes across Knightsbridge and the surrounding areas from our Montpelier Street base — a realistic number given on the call.
Can you fit locks that meet my insurance policy?
Yes — BS3621 five-lever mortices for timber doors, TS007 3-star or Sold Secure Diamond cylinders for uPVC and composite. Tell us your policy and we'll fit and name it on the invoice.
Do you work with landlords and managing agents?
Regularly — tenancy changeovers, master key suites, communal door entry repairs, invoiced on account rather than job by job.
Do you install CCTV and access control as well as locks?
Yes — access control for communal entrances, CCTV positioned to cover real entry points, and master key systems for multi-unit buildings.
