Key-Alike Systems
Knightsbridge Locksmiths fits key-alike systems for homes and businesses across Knightsbridge and London — one key operating several locks of the same type, so a keyring stops multiplying every time another door or padlock is added.
Not Every Property Needs the Same Key-Alike Setup
A homeowner juggling a front door, back door and shed padlock needs a very different setup from a landlord running several flats, or an office with a run of internal doors. Telling us how many openings and what type they are means we can confirm straight away whether keying them alike is practical, and order the right cylinders.
Homes
Front door, back door and outbuilding padlocks all opened with the one key, instead of three.
Rental Properties
Several flats or units under one landlord, each keyed the same for straightforward handovers.
Offices
A run of internal doors sharing one key, without needing a separate key for each room.
What Our Engineers Can Do For You
From a pair of matched padlocks to a full run of internal doors, one engineer sees the job through — quoted before we start, itemised on the invoice after.
Cylinders, Combinations and What Actually Matters
Keying locks alike depends on matched cylinders being ordered and fitted correctly from the start — retrofitting it later usually means replacing barrels that were never designed to share a combination. We plan the setup properly before anything is fitted.
Matched cylinders, fitted properly
Cylinders manufactured to share one combination, not adjusted after the fact.
Works across brands and types
Padlocks, euro cylinders and mortice locks can often be brought into the same setup.
Room to expand later
Extra locks added down the line can usually be matched to the existing combination.
Still meets insurance standards
BS3621 and TS007 3-star options available within a key-alike setup, not just basic cylinders.
Built on Proof, Not Promises
Planned before it's quoted
We check which locks can realistically be matched before any figure is given, not after fitting begins.
Priced before work starts
Cylinder count and type are quoted upfront — no surprises on the invoice.
Fully licensed and insured
Our engineers carry ID and full public liability cover on every job, residential or commercial.

Key-Alike Setups Across Our Coverage Areas
Property types change street by street across Central London — here's how a key-alike setup looks in four of the areas we cover most.
Key-Alike Systems Knightsbridge (SW7)
Mews houses and period conversions around Beauchamp Place often have a front door, a rear gate and an outbuilding, each on a different lock. Matching them to one key removes the guesswork of which key fits which door.
Key-Alike Systems Chelsea & Belgravia (SW3 / SW1X)
Managing agents running several units around King's Road or Eaton Square use key-alike setups to keep handovers simple, without needing a different key labelled for every single door.
Key-Alike Systems South Kensington (SW7)
Converted flats around Exhibition Road and Gloucester Road often share communal storage or bike stores, where residents benefit from one key covering their own door and shared padlocks alike.
Key-Alike Systems Pimlico & Belgravia (SW1P / SW1E)
Terraced houses around Warwick Way and Eaton Square with a front door, side gate and shed all get matched together, so one key handles the whole property rather than a bunch that all look the same.

FAQs — Key-Alike Systems
What does "key-alike" actually mean?
Several separate locks are fitted with cylinders that all share the same combination, so one key opens every one of them, rather than needing a different key per lock.
Can existing locks be matched, or do they all need replacing?
It depends on the make and condition of what's already fitted. We check compatibility during the survey — some cylinders can be matched, others need replacing to bring them into the same setup.
Does this reduce security compared to separate keys?
Not if it's specified properly — the individual cylinders can still meet BS3621 or TS007 3-star standards. The convenience comes from the key, not a weaker lock.
Can I add more locks to the setup later?
Usually yes — an additional lock can be ordered to match the existing combination, so you're not starting from scratch each time.
Is this suitable for a rental property with several units?
Yes — it's a common setup for landlords and managing agents who want a simpler handover process without a labelled bunch of different keys.
Do you cover this service outside Knightsbridge?
Yes — alongside our core Knightsbridge, Chelsea and Belgravia ground, we fit key-alike systems for homes and businesses across Central London and the surrounding boroughs.
