Emergency Locksmith Services in Cambridge & the Cambridge area
Being locked out of your house is one of those problems that always seems to happen at the worst moment, whether it is late at night outside a terraced home in Romsey, after a long shift near the Science Park, or when the front door of a flat off Mill Road swings shut with the keys still on the kitchen table. Chesterton Locksmith is a 24/7 mobile emergency locksmith covering Cambridge and the villages around it, so when you need help getting back inside we send a trained technician straight to you rather than asking you to come to us.
Open 24 hours, 7 days a week · Fully insured
We work across the whole city and the surrounding area, from Chesterton, Arbury and Kings Hedges through to Cherry Hinton, Trumpington, Newnham and the commuter villages out towards the A14 and M11. Our locksmiths carry the tools and common parts needed for the Yale-type nightlatches, mortice deadlocks and uPVC multipoint locks found on most Cambridge homes, and wherever possible we focus on damage-free entry so your door and lock keep working afterwards. Call 01223 912859 at any hour and a real person will talk you through what happens next.

What happens when you call our emergency locksmith Cambridge team
When you ring 01223 912859 the first thing we do is listen. We will ask a few simple questions about your situation: what sort of door you have, whether it is a wooden front door with a nightlatch, a uPVC or composite door with a multipoint lock, or an internal door; whether the key is lost, snapped or locked inside; and where in Cambridge you are. Those details let us send the right locksmith with the right equipment the first time, rather than making a wasted trip.
Because we are mobile and local, we send a locksmith straight away and are usually with you in about 30 minutes, depending on where you are and the traffic around the town centre. Before anyone sets off we confirm a clear, up-front price on the phone so there are no surprises when we arrive. The final figure depends on the type of lock, the time of day, how far we travel to reach you and whether any replacement parts are needed, and we explain all of that plainly before any work begins.
On site, our first job is to confirm you are entitled to be there, which usually just means checking some straightforward proof of residence or ownership. We then look for the least invasive way in. In most house lockouts we can open the door without damaging it, and only where a lock has genuinely failed or been forced would a lock change be the sensible option. Our technicians are experienced and fully insured, and we will always talk you through what we are doing and why.
Bedroom, bathroom and internal door lockouts
Not every lockout happens at the front door. We are regularly called out to internal doors, a bathroom with a toddler shut inside, a bedroom door that has jammed, or a privacy latch that has slipped and left someone unable to get into a room. These calls can feel urgent, especially where a child or a vulnerable person is on the other side, so if anyone is at risk you should always ring 999 first and then call us.
Internal door locks are generally simpler than external ones, and in many cases we can release a stuck privacy bolt or tubular latch cleanly without harming the door or frame. Older Cambridge homes, the Victorian terraces around Petworth Street and the larger period properties in the leafier roads near the river, often have original rim locks and mortice furniture that need a careful hand, and our locksmiths are used to working with them.
Where an internal mechanism has worn out or broken, we can repair or replace the handle and latch so the door works properly again afterwards. We would rather leave you with a door that opens and closes as it should than simply force it and walk away. If you are unsure whether your problem counts as an emergency, call 01223 912859 and we will give you honest advice before sending anyone out.
Locked out of the house with a nightlatch on the door
One of the most common calls we take is from people who are locked out of the house with no key because a nightlatch has done exactly what it is designed to do. Yale-type nightlatches lock automatically when the door closes, so stepping out to take the bins round or answer the door, then hearing the latch click behind you, is an easy way to end up stranded on the pavement with the keys still inside.
If this happens to you, the calm thing to do is first check for any other way in. Is a back door, patio door or ground-floor window unlocked, and is there a spare key with a neighbour, a partner or a nearby family member. Do not be tempted to climb, break glass or force a window, as the cost and risk of that usually far outweighs a professional opening, and it can leave your home insecure.
When a spare is not an option, this is a textbook job for a mobile locksmith. A nightlatch that is simply on the latch, rather than deadlocked, can very often be opened without any damage to the door or the lock itself, which means you can carry on using the same key afterwards. We cover this kind of home lockout across Cambridge day and night, so once you have checked the obvious options, pick up the phone.
Snapped and broken keys, and why not to dig at the cylinder
Keys snap. Years of use, a stiff lock, cold weather or simply turning a little too hard can leave half the key in your hand and the other half stuck in the barrel. It is tempting to grab tweezers, a knife or a screwdriver and go hunting for the broken piece, but we would gently ask you not to. Poking at the cylinder usually pushes the fragment deeper, scratches the pins and can turn a quick extraction into a full lock change Cambridge job.
Our locksmiths carry proper extraction tools designed to grip and withdraw a broken key without damaging the mechanism. In many cases we can remove the snapped section and get your existing lock working again, which is far better than ruining a cylinder that was otherwise perfectly fine. If the lock was already failing, we can advise on a sensible door lock replacement Cambridge option at the same time.
This matters especially on uPVC and composite doors, where the euro cylinder itself can snap under force. If you have a uPVC door lock repair need in Cambridge, we can fit anti-snap, TS007 3-star rated cylinders that resist the common snapping attack, which is something many insurers look favourably on. We will always talk you through whether a repair or a new cylinder is the right call for your particular door.
Securing a damaged door after a break-in or forced entry
If you come home to a forced door, or you wake to find someone has tried to get in, your first call should be to the police on 999 so the incident is logged. Once you have done that, your next priority is making the property safe again, and that is where our 24 hour locksmith Cambridge service comes in. We understand how unsettling a break-in is and we work quickly and calmly to get you secure.
Depending on the damage, we can replace a snapped or drilled cylinder, fit a new mortice deadlock or nightlatch, realign a buckled uPVC door, or carry out a complete lock change so no old keys will work. For homes where the door or frame is badly damaged, we can secure the opening and get it closing and locking again so you are not left exposed overnight. We will explain exactly what needs doing and confirm the price before we start.
We help homeowners, tenants, landlords and letting agents across the city with this kind of work, from flats near the station to family houses out towards Milton and Histon Road. If you have had an attempted break-in anywhere in or around Cambridge, call 01223 912859 and we will get someone out to make your home secure again.
Evenings, weekends and bank holidays — one emergency locksmith service, all hours
A lockout does not keep office hours, so neither do we. Our emergency locksmith service runs around the clock, including evenings, weekends and bank holidays, with the same trained and insured technicians answering the phone and turning up at your door. There is no separate out-of-hours operation to be passed around; you reach us directly on 01223 912859 whenever you need us.
Naturally a call at 2am carries different costs from a mid-morning weekday visit, and the time of day is one of the factors we take into account when we quote. What never changes is that we tell you the price clearly on the phone before we set off, so whether it is a quiet Tuesday afternoon or a busy Saturday night in the town centre, you know where you stand before anyone arrives. A call-out charge applies, and we make it plain upfront rather than adding it at the end.
This matters most for the people who call us at night, a single parent locked out with the children already in bed, a student near the colleges who has lost a key before an early start, or a shift worker home late to a door that will not open. Whatever the hour and wherever you are around Cambridge, a damage-free opening is usually possible, and we aim to be with you quickly so you can get back inside and get on with your evening.

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 much do locksmiths charge per job?
There is no single fixed figure because the cost depends on the job. The main factors are the type of lock or door, the time of day, how far we travel to reach you and whether any replacement parts are needed. We confirm an exact, up-front price on the phone before anyone is sent out, so you always know the full cost before we begin work.
I locked myself out of my house. What should I do?
Stay calm and first check whether any other door or a ground-floor window is unlocked, and whether a neighbour, partner or family member holds a spare key. Do not try to force a window or break glass, as that usually costs far more than a professional opening. If you cannot get in safely, call 01223 912859 and we will send a locksmith straight away, usually reaching you in about 30 minutes.
What should I do if I have lost my only house key?
If your only key is genuinely gone and you are locked out, a mobile locksmith can open the door for you, in many cases without damage. Because a lost key could be in someone else's hands, it is sensible to change the affected lock or cylinder afterwards so the missing key no longer works. We can open the door and, if you wish, fit a new lock in the same visit.
Can you open the door without damaging it?
In most house lockouts, yes. A nightlatch that is simply on the latch, or a standard uPVC multipoint lock, can very often be opened cleanly so your existing key keeps working afterwards. Damage-free entry is always our first approach, and we only move to drilling or a lock change when a lock has failed, been forced, or there is genuinely no other way in.
How quickly can you get to me in Cambridge?
We are a local mobile service, so we send a locksmith straight away and are usually with you in about 30 minutes. The exact time depends on where you are in the city or the surrounding villages and on traffic around the town centre, so we give you a realistic timing when you call rather than promising an exact minute.
Do you really answer the phone at night and on bank holidays?
Yes. Our emergency line is answered 24 hours a day, every day of the year, including evenings, weekends and bank holidays. You reach our own team directly on 01223 912859, and the same trained, insured locksmiths handle calls at night that handle them during the day.
My key snapped in the lock. Can you fix it?
Usually, yes. Please avoid poking at the barrel with tools, as that tends to push the broken piece deeper and can damage the cylinder. Our locksmiths carry proper extraction tools to remove the snapped section, and in many cases the existing lock can then keep working. If the lock was already worn, we can fit a replacement at the same time.
Are you insured, and will you check I live there?
We are fully insured, and our technicians are trained and experienced. For your security and ours, we carry out a simple check that you are entitled to access the property before opening it, which normally just means showing some straightforward proof of residence or ownership once the door is open.
