Moving Home Locksmith
Previous owners, letting agents, cleaners and builders may all still have a way into a property you've just bought or rented. Knightsbridge Locksmiths changes locks on moving day across Knightsbridge and London, so it's genuinely your home from the moment you arrive.
Not Every Move-In Needs the Same Job
A freehold house, a rented flat and a new-build with a communal entrance all raise different questions when you move in. Telling us the property type and the situation — bought, rented, renewing a tenancy — means we bring the right cylinders and know which locks actually need changing.
Buying a Home
Every external lock changed, since there's no way to know how many copies exist from previous owners.
Starting a Tenancy
Front and back doors changed between lets, so a previous tenant's spare no longer works.
Communal Entrances
Flat door changed while respecting the building's shared entry system.
What Our Engineers Can Do On Moving Day
From a straightforward lock swap to a full security upgrade for a new home, one engineer sees the job through — quoted before we travel, itemised on the invoice after.
What Changing the Locks Actually Achieves
You can't know how many keys exist for a property you didn't fit the locks on yourself — estate agents, previous tenants, cleaners and tradespeople may all have held one at some point. A lock change on moving day closes that off completely, rather than hoping nobody kept a spare.
Every external lock covered
Front, back and side doors changed together, not just the one that feels most obvious.
Insurance-standard cylinders
BS3621 or TS007 3-star fitted as standard, named on the invoice for your policy.
Done before you unpack
Most homes are completed same-day, so it's sorted before the boxes are even open.
Landlord and letting agent friendly
Invoiced clearly for tenancy paperwork or an inventory report if needed.
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 doors and property type on the phone and the figure quoted is the one on the invoice.
Non-destructive fitting
Cylinders swapped cleanly wherever the existing mechanism allows, without unnecessary work to the door.
Fast across Central London
Working from Montpelier Street puts Knightsbridge, Chelsea, Belgravia and South Kensington minutes away.

Lock Changes for New Homes, Area by Area
Property types vary street by street across Central London — here's how a moving-day lock change looks in four of the areas we cover most.
Moving Home Knightsbridge (SW7)
Period conversions around Beauchamp Place and mews houses off Brompton Road often have older mortice locks alongside a modern cylinder — both get covered on moving day, not just the obvious one.
Moving Home Chelsea & Belgravia (SW3 / SW1X)
Rental turnover around King's Road and the terraces near Eaton Square is steady, and letting agents here regularly book us between tenancies so a new tenant never inherits a previous one's spare key.
Moving Home South Kensington (SW7)
Converted flats around Exhibition Road and Gloucester Road usually have a shared entrance as well as your own front door — we change your flat door lock while working properly within the building's communal system.
Moving Home Pimlico & Belgravia (SW1P / SW1E)
Terraced houses around Warwick Way and Eaton Square typically have front, side and rear access, all of which get covered on the same visit so nothing is left on the original key.
Where We Cover Moving-Day Lock Changes
Our core ground is Knightsbridge, worked from 4 Montpelier Street, SW7 — reaching every SW1 postcode plus the streets and neighbourhoods that make up Belgravia, South Kensington and Chelsea, with cover extending across wider Central London too.

FAQs — Moving Home Locksmith
Should I really change the locks if I've bought a home?
Yes — there's no way to know how many keys exist from previous owners, builders or estate agents. A lock change closes that off completely rather than hoping nobody kept a spare.
Do tenants need to change locks too, or just homeowners?
It's just as relevant for tenancies — a previous tenant's spare key stops working the moment the locks are changed between lets.
Can you fit new locks on the same day as completion?
In most cases yes — timed around your completion or move-in appointment, so it's one of the first things sorted rather than an afterthought.
Do all the external doors need changing, or just the front door?
All of them, ideally — front, back and side access all get covered, since any one of them could still be on an old key.
Will new locks meet my home insurance requirements?
Yes — BS3621 five-lever mortices or TS007 3-star cylinders are fitted as standard and named on the invoice for your policy.
Do you invoice in a way letting agents accept?
Yes — a clear, itemised invoice suitable for tenancy paperwork or an inventory report.
