Locks, keys and security for Knightsbridge shops, offices, letting agents and managed buildings. Available 24 hours a day, with a locksmith at most business premises in 10–15 minutes.
A jammed shopfront lock at 9:45 costs you the morning’s trade. A lost key, or a member of staff leaving with one, leaves every door it opens exposed. Knightsbridge Locksmith is a local, mobile locksmith based in SW7, a few minutes from Brompton Road, Sloane Street and the streets around Harrods.
We handle the urgent calls: lockouts, broken locks and burglary repairs. We also do the planned work that stops those calls happening again: lock changes, anti-snap upgrades and key systems. All of it is fitted around your trading hours by DBS-checked locksmiths who work on commercial premises across SW1, SW3 and SW7 every week.
From an emergency call at midnight to planned security work across a whole building, Knightsbridge Locksmith offers the full range of locksmith services a business needs, from one local team.
When a lock fails at closing time, or you’re locked out before opening, you need an emergency locksmith who is already nearby. Our emergency locksmith service runs 24 hours a day, 365 days a year, and every emergency call is our top priority.
Call 07309 909989 and we’ll give you an arrival time on the phone. Most emergency calls in the Knightsbridge area are reached in 10–15 minutes, and the surrounding areas in 15–20 minutes.
Our locksmith services cover every door on your premises, from the shopfront to the fire exit. Each service below is available as an emergency call-out or as planned work at a time that suits you.
Locked out of the shop, office or stockroom? We open the door using non-destructive entry wherever possible and get you trading again.
Emergency door openingSticking, stiff, loose or broken locks are repaired on the spot where possible, with common parts carried in the van.
Staff left, keys lost or a new lease? We change or rekey every lock on your premises in one visit.
Lock changeWe repair and replace the hook locks, cylinders and floor springs fitted to glass and aluminium shopfronts.
We supply, install, repair and open Banham locks, which are common across SW1 and SW3.
Banham lock installationWe fit TS007 3-star and Sold Secure Diamond cylinders and BS3621 mortice deadlocks, the standards insurers ask for.
High-security locksOne key for each person, opening only the doors they need, on keys that can’t be copied without your authorisation.
Master key systemsWe fit and repair panic bars, push pads and emergency exit devices, so fire exits open easily from inside and stay secure from outside.
We adjust or replace closers, hinges and keeps on doors that slam, drag or won’t latch.
Door won’t latch or closeWe open safes and change safe locks and codes. Standard safes are usually opened the same day. High-security safes are assessed first and opened within about a day, with as little damage as possible.
We make your premises secure the same night and fit stronger locks than the ones that failed.
Change locks after theftOn Brompton Road, Sloane Street, Beauchamp Place and the streets around Harrods, we handle shopfront locks, stockroom security and lockouts before opening time.
We change locks when staff leave, restrict keys to server and file rooms, and set up access that works in a shared building.
We change locks between tenancies, handle tenant lockouts and fit insurance-approved locks, with an itemised receipt for every property.Locksmith for letting agents
We look after communal doors, bin stores, plant rooms and master keying for blocks across SW1, SW3 and SW7.
We secure back doors, cash offices and treatment rooms, and do the work out of hours so you never close for a lock job.
A broken lock or faulty lock on commercial premises is a security gap from the moment you notice it. We repair it on the spot where we can and replace it when we can’t. Either way, the door is secure before we leave.
We repair door locks that stick, won’t turn, won’t latch or need force to lock. Typical repairs include freeing a seized mechanism, realigning the keep so the bolt throws fully, and replacing worn springs and levers. If a repair would cost close to a new lock, we’ll tell you and let you choose.
Change your locks when keys are lost, a member of staff leaves without returning a key, or you take over new premises. On most doors we fit a new cylinder and keep the rest of the lock, which is quicker and cheaper than a full replacement. If you need all the locks changed, we can key them alike or put them on one master key in the same visit.
| Lock type | Where you’ll find it | What we do |
|---|---|---|
| Five-lever mortice deadlocks (BS3621) | Timber office doors, and back doors of shops and restaurants | Repair, replace, or upgrade to an insurance-approved lock |
| Mortice sashlocks | Internal office doors and fire doors | Repair or replace |
| Rim cylinders and night latches | Period front doors and communal entrances | New cylinder, or upgrade to a BS3621 night latch (Yale lock repair) |
| Euro cylinders | Aluminium shopfronts and modern doors | Replace with anti-snap cylinders |
| uPVC multipoint locks | Rear doors and fire exits | Repair or replace the gearbox, cylinder or whole lock |
| Window locks | Ground-floor and basement offices and stockrooms | Fit key-operated window locks |
| Banham locks | Townhouses, offices and mansion blocks across SW1 and SW3 | Repair, change or install (Banham lock repair) |
Many Knightsbridge businesses have a uPVC or composite door at the back, even behind a period shopfront. When a uPVC door lock fails, the handle usually drops or the multipoint lock won’t engage. We replace the gearbox or the whole lock and adjust the door so it closes and locks cleanly.
Most period buildings in Knightsbridge use mortice locks on the main door, often paired with a rim cylinder night latch. Mortice locks sit inside the door, which makes them strong, but a replacement has to match the size and backset exactly. We carry the common sizes of mortice locks, five-lever deadlocks and rim cylinders, so most lock replacement jobs are finished in one visit.
New door, new fit-out or extra security? We handle lock installation on timber, aluminium, uPVC and glass doors, including Banham locks, mortice locks and anti-snap cylinder locks. Every lock installation is fitted, tested and handed over with all keys accounted for.
A standard euro cylinder can be snapped in seconds. Snapping or drilling the cylinder is one of the most common ways burglars get through a commercial door. Anti-snap cylinders are built to break at a sacrificial line and leave the lock locked.
We fit cylinders rated TS007 3-star or Sold Secure Diamond, the grades most commercial insurers recognise. A typical security upgrade can be done in one visit:
When we’re on site for any job, ask us to check your other doors. We’ll tell you which ones are the weak points, and you decide what, if anything, to upgrade. High-security locks
If your premises have been broken into, call the police first and get a crime reference number. Then call us on 07309 909989. We’ll make the building secure the same night, whatever the time.
In Knightsbridge, a locksmith drilling on the shop floor during trading hours isn’t an option. We schedule planned work for early mornings, evenings, weekends or overnight, so customers and staff never see us.
Master keying gives each person one key that opens exactly the doors they need. The director’s key opens everything, the manager’s opens the stockroom and office, and staff keys open the front door only. Keys are on a restricted profile, so they can’t be copied at a high-street key cutter. When a key goes missing, you replace one cylinder instead of every lock in the building.
We design, supply and fit master keyed locks for offices, shops and mansion blocks, working with EVVA, Abloy, Mul-T-Lock, Assa Abloy and other master-keyable brands.
Master key systems in KnightsbridgeWe change locks between tenancies, often on the same day the keys come back. We handle tenant lockouts, checking ID before we open any door, and fit BS3621 locks so your landlords’ insurance stays valid. Every job comes with an itemised receipt showing the property address.
Letting agent and landlord locksmithMost boutique fronts in Knightsbridge are narrow aluminium or frameless glass doors. They use hook locks, slim cylinders and floor springs that a general handyman rarely carries. When one fails, you either can’t open up or can’t lock up. We repair both, 24 hours a day.
The brief. An office on Brompton Road needed Banham locks fitted across three floors, without disrupting the staff working there.
What we did. We surveyed every door first and agreed a plan floor by floor. The installation was scheduled around staff hours, so the office kept running throughout. Keys were handed over with a clear record of who holds which key.
The result. The work was finished discreetly and to a high standard. The office now uses us as its regular locksmith.
We’re a local locksmith based in Knightsbridge, not a national call centre sending whoever is free. You get a quick response, and a team that already knows the doors, locks and buildings on your street.
Every job gets the same reliable service, whether it’s a single lock repair or security work across a whole building. Customer satisfaction is the measure we care about most, and local customers rate us 4.9 out of 5.
