Commercial Lock Change
When a member of staff leaves, a lease changes hands, or a break-in attempt leaves a lock damaged, the security of your Cambridge office or shop cannot wait.

Why a Commercial Lock Change Is Often the Right Decision
Businesses in Cambridge face a specific set of security pressures that residential properties rarely encounter. High staff turnover, shared keyholders, subletting arrangements and the sheer number of people who may have held a key to your premises over time all create risk. Unlike a home, a commercial property may have issued keys to delivery drivers, cleaning contractors, previous tenants, former directors or seasonal employees — and once a key leaves your direct control, there is no reliable way to know how many copies exist. Changing the lock cylinder, or in some cases the entire lock, is the only dependable way to restore full control over who can enter your premises. It is a straightforward, cost-effective step that many Cambridge business owners delay longer than they should.
The decision is especially pressing after a staff departure that did not end amicably, after a burglary or attempted forced entry, or when you are taking over a leased unit and have no way of knowing what keys the previous occupant distributed. Our technicians will assess the existing hardware, advise on the most suitable replacement, and carry out the work with minimal interruption — most cylinder swaps on a standard commercial door take under an hour.
Commercial Lock Change and Upgrade Options We Carry Out
Our commercial lock change service covers the full range of door types found in Cambridge business premises. Euro cylinder replacements on aluminium-framed office doors and uPVC shopfronts are among the most common jobs we complete. We fit anti-snap, anti-pick and anti-drill cylinders as standard where the door profile allows it, and we can advise on TS007 3-star rated options for higher-risk situations. For timber office doors with traditional mortice locks, we can upgrade to a British Standard 5-lever mortice deadlock — something insurers frequently specify in commercial policy documents. We also work on multipoint locking systems on composite and uPVC doors, nightlatch replacements on internal office doors, and rim lock changes on older Cambridge commercial properties where period fittings are still in use.
If your premises have a master key arrangement — where certain staff hold keys that open multiple doors while others hold keys limited to their own office — we can reconfigure or completely replace the system when staff changes make it necessary. A well-designed masterkey system gives you granular control over internal access without the cost and complexity of electronic access control, and it remains a practical solution for many small to medium-sized Cambridge businesses. For larger premises or those requiring audit trails, we can discuss the options available and help you decide what level of security architecture suits your operation.
After Staff Changes: Protecting Your Premises Without Disruption
The period immediately after a key employee leaves is one of the most overlooked security vulnerabilities in any business. Human Resources teams focus on offboarding procedures, IT departments disable system access, but physical key security is frequently an afterthought. If the departing member of staff held a key — or could have had one cut without your knowledge — your lock should be changed before the end of that working day where possible. Our mobile service means a trained technician can be at your Cambridge office or shop quickly, and we are usually on site within about 30 minutes of your call. We can often schedule the visit to coincide with a natural break in trading, reducing the impact on your customers and staff.
We work with business owners, office managers, letting agents and managing agents across Cambridge on a planned as well as reactive basis. If you know a lease is ending or a staff restructure is coming, you can arrange the lock change in advance so that new keys are ready the moment the transition takes place. Call us on 01223 912859 at any point and we will talk through the timing and logistics with you before anyone travels out.
Out-of-Hours Emergency Call-Outs and 24-Hour Cover
A broken lock at the end of a trading day, a forced entry discovered first thing in the morning, or a shopfront that will not secure properly before closing — these are situations where waiting until the next working day is simply not an option. As a 24-hour locksmith Cambridge businesses can rely on any time, we operate with no cut-off and no reduced weekend service. Our emergency commercial locksmith response covers the whole of Cambridge and the surrounding area: whether your premises are on the Grafton Centre side of the city centre, out near the Cambridge Retail Park, or on one of the business estates further from the town centre, we will send a technician straight away.
When you call 01223 912859, we will take the details of your situation, confirm an exact up-front price before anyone sets out, and get a technician moving immediately. The price we quote reflects the specific factors involved — the type of lock and door, the parts required, the time of day, and travel distance — so there are no surprises on completion. We answer every call ourselves; there is no out-of-hours answerphone.

Frequently asked questions
How quickly can you reach my Cambridge office or shop in an emergency?
We send a technician straight away when you call, and we are usually with you in about 30 minutes. The exact arrival time depends on where our nearest available technician is at that point, but we will give you a realistic expectation when you call 01223 912859. We cover the whole of Cambridge around the clock, including evenings, weekends and bank holidays.
What factors affect the cost of a commercial lock change?
Several things go into the final quote: the type of lock and door involved (a standard euro cylinder on an aluminium office door is a different job from a multipoint system on a composite shopfront), the grade of replacement hardware required, the time of day, and the travel distance to your premises. We confirm an exact price with you before anyone travels out, so you know what to expect before work begins. There are no additional charges added at the end.
Do I need to change the whole lock, or just the cylinder?
In many cases, particularly on modern uPVC and aluminium-framed commercial doors, we only need to replace the euro cylinder — the barrel that the key turns — rather than the entire lock body. This is quicker, less disruptive, and uses the existing door hardware. For older mortice locks or where the lock body itself has been damaged, a full door lock replacement may be necessary. Our technician will assess this when they arrive and explain what is needed before starting.
Can you change locks on multiple doors in one visit?
Yes. If you need a lock change across several doors in your premises — for example, a front entrance, a rear access door, and a number of internal office doors — we can carry out all of that in a single visit. If you are also looking to have those locks keyed to a masterkey system so that one key opens designated doors while individual staff keys are restricted to specific areas, we can configure that at the same time. Tell us on the phone what you need and we will make sure the technician comes prepared.
How do you verify that a caller is entitled to change the locks on a commercial property?
Before any work begins, our technician will ask to see proof that you have the right to authorise changes to the property — this might be a lease, a business rates document, a letter from a managing agent, or similar. This is standard practice and protects both you and the building. If you are a managing agent acting on behalf of a landlord, it helps to have written authorisation or contact details for the landlord available. We will never carry out a commercial lock change without reasonable verification of authority.
Is a lock change necessary after every staff departure, or only in certain situations?
It depends on the circumstances. If a staff member held a physical key to any exterior door and either did not return it or potentially had a copy made, changing the relevant lock is the safest course of action. If keys were managed through a strict signing-in system, all copies are verified as returned, and the departure was straightforward, the risk is lower — but many business owners still choose to change as a precaution, particularly for access to high-value areas. We are happy to talk through the specific situation when you call, so you can make an informed decision rather than acting on assumption.
