Master Key Systems
Bespoke master key systems designed for your business. Allow management access to all areas while restricting employees to designated zones. Scalable systems that grow with your organisation. We design, install, and maintain master key suites for premises of all sizes. Read our in-depth guide to master key systems for businesses to understand the different suite types and how to plan one for your site.
Access Control Systems
Electronic access control with keypad, card reader, or fob entry. Monitor who enters your premises and when, revoke access instantly when staff leave, and eliminate the cost and risk of managing physical keys.
High-Security Locks
Commercial-grade locks from leading manufacturers including ASSA ABLOY, Mul-T-Lock, and Banham. Anti-pick, anti-drill, and anti-bump protection with restricted key profiles that prevent unauthorised key duplication. Our guide on what high-security locks are and when you need them covers the ratings and standards to look for.
Emergency Commercial Locksmith
24/7 emergency lockout service for commercial premises. Locked out of your office, shop, or warehouse? We attend quickly and gain entry with minimal disruption. Emergency lock changes and break-in repairs also available around the clock. Understanding how burglars break into properties in London can help you identify and close the vulnerabilities most commonly exploited on commercial doors.
Safe Opening & Installation
Professional safe opening when combinations are lost or mechanisms fail. We also supply and install commercial safes for securing cash, documents, and valuables.
Commercial vs Residential Locksmithing: Why Business Premises Are Different
Securing a business is not the same as securing a home. Commercial premises see far higher footfall and a constant turnover of key holders - staff, contractors, cleaners and deliveries - so access has to be revocable and, ideally, auditable. That alone shifts the work towards access control and master key systems that domestic jobs rarely need.
The hardware differs too. Many commercial doors use BS8621 thumb-turn locks or panic hardware so people can escape without hunting for a key, rather than relying on a domestic euro cylinder alone. Insurers also impose specific lock standards on commercial policies, and fitting non-compliant hardware can leave a claim in dispute. Much of our commercial work is therefore scheduled out of hours so we can change locks or rewire access without interrupting trading.
British Standards & Insurance Compliance for London Businesses
Most commercial insurance policies set a minimum lock standard, and meeting it is what keeps your cover valid. The standard that applies depends on whether the door is also a fire escape. Our guide to lock types and British Standards explains the detail, and we fit to the relevant standard on every commercial job.
BS3621
The insurance-grade standard for mortice and rim locks that are keyed on both sides. Common on final doors that are not designated escape routes, where you want the door locked from inside and out.
BS8621
Keyless egress: a thumb-turn lets occupants exit from the inside without a key, while still locking securely from outside. Used where safe escape is required on a fire route.
BS10621
A lockable thumb-turn that allows keyless escape during trading but can be locked out of hours, so the door cannot be opened from inside when the premises are empty.
TS007 3-star & Sold Secure Diamond
Cylinder ratings that resist lock snapping, a common attack on exposed shopfront and office doors. Anti-snap, anti-pick, anti-bump and anti-drill cylinders protect the most vulnerable point.
Because UK locksmithing is unregulated, the safeguard for a business is to choose a trade that works to recognised British Standards and documents what it fits. We issue itemised invoices listing the parts and ratings used, which supports both your accounting and any future claim. Requirements vary between policies, so we recommend confirming your insurer's exact lock specification before any fit-out or upgrade. For shopfront and office doors with multipoint locking, see our uPVC and multipoint locksmith service.
Fire Safety & Emergency Exit Hardware
On an escape route, security must never get in the way of getting out. We fit thumb-turn locks, panic bars and push pads so occupants can leave without a key or special knowledge, which supports your duties under the Regulatory Reform (Fire Safety) Order 2005. The skill is balancing that life-safety requirement with keeping the door genuinely secure against intruders.
For public-facing premises, escape hardware also needs to stay accessible, in line with the Equality Act, so it can be operated easily by everyone. We can advise on hardware that meets both insurance and fire requirements together - for example a BS8621 thumb-turn or a panic latch on a final exit - but the specifics should always be confirmed against your premises fire risk assessment. New escape doors and panic hardware are part of our commercial door and lock installation work.
Access Control Systems Explained
Access control replaces physical keys with credentials you can issue, manage and revoke from one place. It removes the cost and risk of cutting keys for every member of staff, and it tells you exactly who came and went. We design, install and integrate systems for single doors right up to multi-tenant buildings, and we can tie them into intercom and door-entry for managed premises.
Credential options
Keypad PIN entry
Simple and low cost for lower-risk doors. No tokens to manage, though codes can be shared and should be changed when staff change.
RFID fob & proximity card
The workhorse of most offices. Each fob or card is unique, easy to issue and instantly deactivated if lost or when someone leaves.
Smartphone & Bluetooth
Credentials live on the user's phone, so there is nothing physical to hand out or collect back. Convenient for mobile and hybrid teams.
Biometric (fingerprint)
The tightest control for sensitive areas, since the credential cannot be passed on, borrowed or copied.
A single entrance can run as a standalone system programmed at the door. Multiple doors are better on a networked system with central, often cloud-based, user management - so you administer the whole site from one screen. Networked systems keep an audit trail showing who entered which door and when, which is valuable for HR matters, investigations and insurance. You can also set time and shift-based rules, manage visitors, and apply instant revocation the moment a fob goes missing or an employee leaves.
Behind every reader sits the locking hardware. Electric strikes release a standard latch on a swing door, maglocks (magnetic locks) hold the door with a powerful electromagnet, and electric rim locks or shear locks suit specific door types and traffic levels. We work with established platforms such as Paxton and Salto. Whatever the design, the door must close and align correctly first, and a safe means of exit - a request-to-exit device or emergency break-glass release - is non-negotiable so the system never traps anyone inside. For more background, read our guide on choosing the right access control system.
Master Key Systems: Suites, Tiers and Restricted Keys
A master key system controls who can open what with the fewest keys possible. At its simplest, doors can be keyed-alike so one key opens several locks, or keyed-to-differ so every key is unique. A master-keyed hierarchy combines the two: each person carries a key for their own door, while a master key opens the group.
Larger organisations use a grand master suite, where separate departments or buildings - think schools, hospitals or managed estates - each sit under their own sub-master, all opened by a single grand master at the top. To stop keys being copied at a high-street kiosk, we specify restricted or patented key profiles from makers such as ASSA, Mul-T-Lock and EVVA. Copies can then only be cut on your authority, with an authorised signatory named so no one else can order keys.
We map the hierarchy to your organisation chart and build in spare capacity, so the suite scales cleanly as you add doors, teams or sites. Master key planning works best alongside any commercial lock change or access control project.

What our customers say
Real jobs, real Londoners. A few words from people we have helped.
Access control on the main door kept failing. They diagnosed it, replaced the faulty unit and tidied the wiring the previous lot had left in a mess. Proper engineers.
Needed the shop secured after a staff change. They rekeyed everything in an evening so we opened as normal the next day. Discreet and professional. Good to have a number I trust.
Restaurant front shutter lock packed in on a Saturday night. They came out after close and got us locked up safe so we weren't standing guard till morning. Genuinely grateful.
Fitted a master key system across our office so we could control who gets into the stockroom. Worked around our opening hours, minimal disruption, and labelled everything clearly. Spot on.
Old school service with a modern setup. Booked easily, kept me updated on timing, and did a thorough job. The sort of tradesman you actually want to come back.
Reliable from the first phone call to the finished job. No drama, no mess, fair money. Recommended them to two neighbours already and both were happy too.
Friendly, fast and honest, which is all you really want from a locksmith. Sorted my problem the same day and didn't make me feel daft for the mistake that caused it. Top marks.
Quick to answer, quick to arrive, and the engineer clearly took pride in the job. Explained everything in plain English without talking down to me. Hard to find these days.
Second time I've used City Locksmith and same good experience both times. On time, polite, knows their trade and charges fairly. Saved their number in my phone now.
Wanted a deadbolt added to a side door that always felt flimsy. The locksmith suggested the right one for the door type and fitted it solidly. Feels completely different now. Worth every penny.
