Commercial Locksmith Services in Cambridge & the Cambridge area
When a lock fails on a shopfront, office or industrial unit, the cost is rarely just the lock itself. A jammed back door at closing time, a snapped cylinder on a trade counter or a lost set of keys for a unit on St John's Innovation Park can stop a business running until it is sorted. Chesterton Locksmith is a 24/7 mobile commercial locksmith covering Cambridge and the surrounding villages, and we come to you with the tools and parts to get premises secure and trading again.
Open 24 hours, 7 days a week · Fully insured

Our technicians are trained, experienced and fully insured, we aim to reach most Cambridge addresses in about 30 minutes, and we confirm an exact up-front price on the phone before anyone starts work. Call 01223 912859 at any hour.

What our commercial locksmith services cover across Cambridge
Our commercial work spans far more than opening a stuck door. For businesses across Cambridge we handle emergency entry when staff are locked out, failed lock repairs and replacements, euro cylinder changes on uPVC and aluminium shopfronts, mortice deadlock servicing on timber doors, and the setting up of key control across a site. We work on retail units, offices, cafes and restaurants, workshops, surgeries, salons and managed blocks, and we are set up to attend quickly because we are mobile and local rather than working from a fixed base.
Here is a clearer picture of what we regularly do for commercial clients: emergency business lockouts; commercial lock changes; euro cylinder replacement and upgrades; mortice deadlock repair and replacement; nightlatch and Yale-type lock fitting; uPVC door lock repair in Cambridge; multipoint lock repair on aluminium and composite doors; fire exit and panic bar checks; overhead door closer adjustment and replacement; broken key extraction; gaining damage-free entry where possible; securing premises after a break-in; door realignment so a lock throws cleanly; handle and escutcheon replacement; anti-snap cylinder upgrades; keyed-alike cylinders across multiple doors; master key setups; lock changes between tenancies; lock servicing on a planned basis; securing communal doors in mixed-use buildings; replacing worn locks on stockroom and office doors; sorting locks that jam in cold or hot weather; attending after lost or stolen keys; adjusting doors that have dropped on their hinges; and advising on hardware that keeps insurers satisfied.
Because every premises is different, the final quote depends on the type of lock, the door it sits in, how many doors are involved, the parts needed and the time of day. We talk all of that through before we set off, so there are no surprises when we arrive. Call 01223 912859 and tell us what has happened and where you are.
When a business needs a full lock change, not just new keys
Sometimes changing the lock is the sensible move rather than carrying on with the one you have. If keys have gone missing, a member of staff has left on poor terms, or you have taken over a unit and have no idea how many keys exist, you cannot be confident who still has access. In those cases a commercial lock change in Cambridge gives you a clean start, and we can key several doors alike so one key runs the whole site if that suits how you work.
A lock change is also the right answer when a lock is worn out or has been forced. On a busy shop door that gets used hundreds of times a day, cylinders and mechanisms wear far faster than on a home. If a key is getting stiff, the latch is sticking, or the door has been tampered with, replacing the cylinder or the full lock is more dependable than nursing a failing one along. We carry common commercial cylinders and mechanisms so most jobs are finished in a single visit.
For landlords and letting agents managing commercial units, planning lock changes around tenancy changes keeps everything tidy and auditable. When a lease ends we can fit fresh cylinders and hand over a known set of keys, so the incoming tenant starts with full control. Ask us about keeping your doors keyed to a simple, manageable scheme.
Shop and office door hardware that keeps your insurer happy
Business insurance often sets conditions on the locks protecting your premises, and the wording can be easy to miss until you need to claim. Timber doors are frequently expected to carry a five-lever mortice deadlock to BS3621, while uPVC and aluminium doors rely on a multipoint mechanism and a euro cylinder. We check what is actually fitted, tell you plainly whether it meets the kind of standard insurers usually look for, and fit hardware that brings you up to scratch where needed.
Shopfronts and aluminium commercial doors have their own quirks. They take heavy daily use, they often have hook bolts and dead bolts driven by a central cylinder, and the closers and hinges need to be right or the lock will never sit true. We service closers so doors shut and latch properly, replace worn cylinders and handles, and make sure fire exit hardware operates freely from the inside while staying secure from outside. Getting these details right protects both your stock and your ability to claim.
If you are unsure what your policy requires, read the specific lock clause or ask your insurer, then call us with the details. We will match the right nightlatch, deadlock or cylinder to the door and the risk, and explain the choice so you know exactly what you are paying for before we fit anything.
Multiple premises and master key systems kept under control
Businesses with more than one door, or more than one site, quickly end up with a pocketful of keys and no clear record of who holds what. A master key system solves this by letting individual keys open only the doors a person needs, while a master opens everything. A manager can hold one key for the whole premises, while a cleaner or delivery driver carries a key limited to a single door. We design these schemes around how your business actually runs.
Keyed-alike setups are a simpler option when you just want one key to open several doors of the same type, which suits small shops and offices with a handful of entrances. For larger or multi-tenant buildings, a tiered master scheme gives you proper key control, and we keep a record so extra keys to the correct specification can be organised later without starting from scratch. This is the kind of groundwork that makes managing premises far less of a headache.
For modern access needs beyond keys, we can talk through electronic and access control options, where fobs or codes replace cut keys and lost credentials are simply cancelled rather than requiring a lock change. Whether you stay with mechanical master keys or move towards access control, we will set it up so adding and removing people is quick and your sites stay secure.
Commercial cylinders, anti-snap upgrades and cylinder replacement in Cambridge
The euro cylinder in a uPVC or aluminium door is the part intruders most often target, because an older cylinder can be snapped quickly. Anti-snap cylinders rated to TS007 3-star are built with sacrificial sections and hardened internals that resist this, and on a commercial door that opens and closes all day they are a straightforward, worthwhile upgrade. We measure your door accurately so the cylinder sits flush rather than protruding, which removes an easy point of leverage.
On timber doors we fit and service mortice deadlocks and nightlatches suited to commercial use, and we extract broken keys, replace worn mechanisms and realign doors that have dropped so the bolt throws cleanly. A door that needs a shove to lock is a door that will eventually fail at the worst moment, so door lock replacement in Cambridge is often about the whole assembly, not just the cylinder. We check hinges, keeps and closers as part of the job.
If you have had a break-in or attempted entry, we prioritise making the premises secure the same day. We can replace a snapped or damaged cylinder on the spot, fit a stronger anti-snap unit in its place, and advise on any further hardware that would reduce the risk of it happening again. Call 01223 912859 and we will send a locksmith straight away.
Out-of-hours and emergency commercial locksmith callouts
Problems rarely wait for opening time. A failed lock at 6am before the first customers arrive, a door that will not secure after an evening shift, or a break-in discovered over a weekend all need sorting now, not on Monday. As a 24 hour locksmith in Cambridge we answer the phone through the night, at weekends and on bank holidays, and send a technician out as soon as we have the details. We are usually with you in about 30 minutes for addresses in and around the city.
When you are locked out of a commercial property, the safe and sensible first steps are to check for a spare key with a colleague or keyholder and to try any alternative entrance you are entitled to use. If that fails, call us. Our emergency locksmith service for Cambridge businesses focuses on gaining entry without damage wherever the lock allows, so you are not left with a repair bill on top of the callout. We will confirm the price for the work before we set off.
After any break-in, our priority is making the premises secure so you can lock up and carry on trading. We replace the damaged lock, check the surrounding door and advise on sensible upgrades. If the police need to be involved, report the incident to 101, or dial 999 if a crime is in progress; we will handle the lock side as soon as it is safe to do so.

Before you call — what to expect
What customers usually ask before booking
Will you need proof that it is my property before you start work? Yes — when you call 01223 912859 we will ask you to confirm your name and address, and our technician will ask to see a form of ID on arrival. This is a standard step we take for every job, and it protects both you and us.
How much will it cost? The final quote depends on a few factors: the type of lock or door involved (for example, a Yale-type nightlatch, a 5-lever mortice deadlock, or a multipoint euro-cylinder lock on a uPVC door), the time of day (evenings, weekends and bank holidays are priced differently from standard weekday hours), travel distance to your postcode, and whether any parts need to be replaced. We confirm an exact up-front price with you over the phone before anyone leaves — you will never be surprised by the total at the end.
How quickly can you get to me if I am locked out in Cambridge? We dispatch a technician straight away and are usually with you in around 30 minutes, though we cannot guarantee an exact arrival time as that depends on current demand and your location. If you are waiting outside late at night, please stay somewhere safe and well-lit — a neighbour's doorstep, a nearby shop, or your car if you have access to it.
Can you help if I rent my flat and do not have a spare key? Yes. We regularly work with tenants, letting agents and housing associations across Cambridge. If you rent, it is worth checking whether your letting agent or managing agent holds a spare key before calling us out, as that may save you time. If not, give us a call on 01223 912859 and we will talk you through the quickest and least disruptive way to get you back inside.
How our quote process works — from first call to confirmed price
1. You call 01223 912859 — any time, day or night. One of our team answers directly. We will ask a few straightforward questions: your location in or around Cambridge, the type of door and lock you have (front door, back door, uPVC, timber, communal entrance, and so on), and whether this is an emergency lockout, a lock change Cambridge job, or a repair.
2. We work out your quote on the call. Using what you have told us — lock type, time of day, any parts we are likely to need, and your distance from our technician — we calculate a clear, all-inclusive price and read it back to you before anything is agreed.
3. You decide, with no pressure. If the price works for you, we confirm the job and dispatch a technician. If you need a moment to think, that is completely fine — we will not rush you, and the quote stands while your situation remains the same.
4. The technician confirms the same price on arrival. Before any work begins, your technician will check the door and lock in person and confirm the quoted price. If anything has changed from what was described on the phone — for instance, a lock that turns out to be a different type — we will tell you straightaway and agree any adjustment before we start.
What to expect from the technician on the day
Arrival in a marked van with ID. Our technician arrives in a clearly marked vehicle and carries identification. Please feel free to ask to see it before you let anyone into your home — a professional locksmith Cambridge residents can trust will always expect that question and welcome it.
A short walkthrough before any work starts. The technician will assess your door and lock, confirm what needs to be done, and explain the process in plain language. For a locked out Cambridge situation this means discussing the least disruptive entry method. For a door lock replacement Cambridge or uPVC door lock repair Cambridge job, it means showing you the parts being fitted and explaining why.
Skilled work carried out tidily. Our technicians are trained and experienced in working on all common UK door types — timber doors with mortice deadlocks or nightlatches, uPVC and composite doors with multipoint locking systems and euro cylinders, and communal block-of-flats entrances. Any debris or packaging from replaced parts is cleared before the technician leaves.
A test and a talk-through at the end. Once the work is complete, the technician will operate the lock with you present, hand over any new keys, and answer any questions you have — including advice on anti-snap cylinders or other security upgrades if your existing hardware raises a concern. If you have further questions afterwards, you can always call us back on 01223 912859 — we answer 24/7.

01223 912859Frequently asked questions
How quickly can you reach my business in Cambridge?
We are a mobile, local team and we send a locksmith straight away once we have your details. For most addresses in Cambridge and the nearby villages we are usually with you in about 30 minutes, though heavy traffic through the town centre or distance out to the surrounding area can affect timing. We will give you a realistic arrival window when you call 01223 912859.
Do you change commercial locks rather than just open them?
Yes. We handle full commercial lock changes, cylinder replacements and mechanism repairs, as well as emergency entry. If keys have been lost, a member of staff has left, or you have taken over a unit, changing the locks gives you a clean set of keys and confidence over who can get in. We carry common commercial cylinders and mechanisms so most jobs are finished in one visit.
Can one key open all the doors across my premises?
It can, with a keyed-alike setup for a few doors of the same type, or a master key system for larger or multi-tenant buildings. A master scheme lets each person hold a key limited to the doors they need, while a master key opens everything. We design the scheme around how your business runs and keep a record so extra keys can be organised later.
What does an emergency commercial callout cost?
The final price depends on the type of lock and door, the parts required, how far we travel and whether it is a daytime, evening or weekend visit. There is a call-out charge, and we make the full cost clear on the phone before anyone comes out, so you can decide with the facts in front of you. We never start work without agreeing the price first.
My uPVC shop door will not lock properly. Can you fix it?
Usually, yes. uPVC and aluminium doors use a multipoint mechanism and a euro cylinder, and problems often come from a worn cylinder, a failing mechanism or a door that has dropped out of alignment. We carry out uPVC door lock repair across Cambridge, replacing the cylinder or mechanism and realigning the door so the lock throws cleanly and locks every time.
Will changing my cylinders help with my insurance?
It can. Many policies expect timber doors to carry a BS3621 five-lever mortice deadlock, and uPVC or aluminium doors to have a sound multipoint lock, often with an anti-snap TS007 3-star cylinder. We check what is fitted and fit hardware that matches the kind of standard insurers look for. Always read your policy's lock clause or ask your insurer if you are unsure.
Are your technicians insured and trustworthy?
Yes. Our technicians are trained, experienced and fully insured, and we carry identification. For any lock change on commercial premises we confirm you are entitled to authorise the work before we begin. If you want to verify who is attending, ask for the technician's details when you call 01223 912859 and we will happily confirm them.
Do you offer anti-snap cylinder upgrades?
We do. Standard euro cylinders can be vulnerable to snapping, which is a common method of forced entry on uPVC and aluminium doors. We fit anti-snap cylinders rated to TS007 3-star, measured to sit flush with the door so there is no exposed section to grip. It is a straightforward upgrade that noticeably strengthens a commercial door.
