A snapped key is one of those moments that stops you cold — you are standing at your front door on a damp Kentish Town evening, the jagged stump of your Yale key still jutting from the nightlatch, and the rest of it is somewhere on the pavement behind you. It happens more often than most people expect, particularly with older brass keys that have been bent and twisted over years of daily use, or with worn cylinders that put extra stress on the blade every time the lock is turned. Before you panic, it is worth knowing that there are one or two things you can safely attempt yourself, and that a skilled locksmith London team can almost always recover the situation without damaging the lock — or your door.
This guide walks you through what you can reasonably try at home, the point at which a professional should take over, and what to expect when you call Kentish Town Locksmiths. Whether you are locked out of your house on a Sunday night or you have just noticed a key has broken off flush with the cylinder face, the advice below will help you make the right call.
## Why Keys Snap — and What You Are Actually Dealing With
Keys break for a handful of predictable reasons: metal fatigue from repeated bending, a lock cylinder that has become stiff or misaligned, forcing a key when the door has dropped slightly on its hinges, or simply an old key that has been cut so many times from copies of copies that it is now thinner than it should be. On a typical North London terrace the front door usually carries a Yale-type nightlatch at the top and a 5-lever mortice deadlock lower down — and both are perfectly capable of trapping a broken key. uPVC and composite doors, which are common on the newer builds and converted flats along Kentish Town Road and around the Regis Road estate, use a multipoint locking system with a euro cylinder, and these present a different challenge because the key fragment can sit deep inside a narrower barrel.
Understanding which type of lock you have matters because it affects what you can safely try. A key broken in a nightlatch sits in a relatively accessible cylinder. A key snapped inside a 5-lever mortice deadlock is a more serious extraction job, and a fragment lodged in a multipoint euro cylinder can sometimes interfere with the locking cam in ways that make the door impossible to open or close at all. Knowing when to stop trying and call a 24 hour locksmith London service is the most important piece of advice on this page.
## What You Can Safely Try Before Calling an Emergency Locksmith London
There are a small number of DIY steps that are genuinely safe to attempt, and they are listed here in the order you should try them. First, do not attempt to force the remaining key fragment further into the lock or use it as a makeshift lever — this almost always makes extraction harder and can damage the cylinder's internal pins. Instead, if any part of the key is still protruding from the keyway, try gripping it firmly with a pair of long-nose pliers and pulling straight out while keeping the cylinder in its neutral position. Applying a small amount of graphite spray lubricant or a dry lock lubricant into the keyway first can help the fragment slide out more cleanly. Avoid WD-40 inside a lock cylinder — it attracts dust and gums up the mechanism over time.
If the key has broken off flush or just below the face of the cylinder, the DIY options become very limited. You can try a broken key extractor tool — a thin hooked probe available from most hardware shops on Kentish Town High Street — by inserting it alongside the key fragment and carefully hooking the serrations to drag the piece out. This requires a steady hand and some patience, and it only works reliably when the cylinder is in the unlocked position. If you are locked out of your house and the cylinder is engaged, the fragment is under tension from the locking cam and manual extraction without the right tools is unlikely to succeed. At this point, the sensible move is to call a professional. If you are unsure, call us on 020 7871 7825 — we can talk you through what you are looking at over the phone before we send anyone out.
## When the Locksmith Saves the Lock — Lock Change London and Beyond
A trained locksmith London engineer carries precision extraction tools — hook picks, broken key extractors of various gauges, and sometimes a plug-following tool — that allow the fragment to be removed without drilling the cylinder. In the majority of cases on a standard Yale nightlatch or a euro cylinder, extraction is clean and the cylinder can be reused or simply replaced with an upgraded unit. This is the preferred outcome because it costs less, causes no damage to the door, and means you are back inside quickly.
There are situations, however, where extraction is not possible without sacrificing the cylinder — typically when the key has sheared off deep inside a 5-lever mortice deadlock and cannot be hooked, or when the cylinder is already worn enough that a door lock replacement London makes more sense than saving it. In those cases our engineers carry out a controlled, non-destructive entry wherever possible, then fit a new cylinder or lock as needed. If your front door has an older cylinder that does not carry the TS007 3-star anti-snap rating — something insurers increasingly ask for — a broken key situation is actually a good prompt to upgrade. We can advise on BS3621-compliant mortice locks and anti-snap euro cylinders on the spot, so your door ends up more secure than it was before the key broke. For uPVC doors specifically, upvc door lock repair London is one of the most common jobs we attend — the multipoint mechanism is robust but the euro cylinder can be vulnerable, and swapping it for an anti-snap grade is straightforward for an experienced engineer.
## Locked Out London — What to Do While You Wait
If you are locked out of your home and waiting for us to arrive, a few practical steps will make the situation easier. Check whether any other entry point is accessible — a back door into the garden, a ground-floor window that is on the latch, or a neighbour or family member who holds a spare key. If you live in a block of flats, your letting agent or the housing association may have a spare for the communal entrance, though they are unlikely to hold one for your own flat front door. If you share your home and a housemate is nearby, it is always worth a quick call before anything else.
Do not attempt to pick the lock yourself. We are aware that searches for things like how to pick a door knob lock or how to pick a lock door knob are common — people are curious and desperate in equal measure when they are locked out of their house on a cold night. The reality is that picking a quality lock without the right tools and training is very difficult, and the attempts most people make (using bobby pins, credit cards, or whatever is to hand) tend to damage the lock face, the door frame, or both. A damaged lock is harder and more expensive to deal with than an intact one, and some insurers will question a claim if there is evidence of attempted forced entry by the policyholder. Stay safe, stay warm, and let a skilled engineer handle it. We send a locksmith straight away and are usually with you in about 30 minutes — call 020 7871 7825 any time, day or night.
## After the Key Is Out — Making Sure It Does Not Happen Again
Once the immediate problem is solved, it is worth taking a moment to think about why the key broke in the first place. If the cylinder was stiff, have it serviced or replaced — a lock that you have to wrestle every day is under constant stress, and it will eventually win that argument. If the door has dropped on its hinges and the latch or bolt no longer aligns cleanly with the keep, a small hinge adjustment can make an enormous difference to how much force the key has to absorb. These are quick fixes that our engineers can carry out at the same visit.
It is also the right moment to think about whether your lock is doing the job your home insurance policy expects. Many insurers for properties in NW5 and surrounding postcodes ask for a 5-lever mortice deadlock to BS3621 on the main front door, and an anti-snap euro cylinder on any uPVC or composite door. If you have been meaning to look into how to change a door lock or whether your existing lock meets the standard, our engineers can inspect what you have and explain the options clearly — including how to change a door lock cylinder to an upgraded anti-snap grade — without pressuring you into unnecessary work. The price for any parts or additional work is confirmed upfront before we begin, so there are no surprises at the end of the job. Factors that affect the final quote include the type of lock, the grade of replacement cylinder or lock body, the time of day, and travel distance — all of which we confirm on the phone before coming out.

Frequently asked questions
Can I remove a broken key from a lock myself?+
Sometimes, yes — but it depends on where the key has broken. If a portion of the key is still protruding from the cylinder, gripping it firmly with long-nose pliers and pulling straight out (with the cylinder in the neutral, unlocked position) can work. A small amount of dry lubricant in the keyway helps. If the key has snapped off flush with the cylinder face, or if the cylinder is in the locked position, DIY extraction is very unlikely to succeed without the right extractor tools, and repeated attempts risk damaging the cylinder. At that point it is safer and cheaper in the long run to call a professional locksmith London engineer who can extract the fragment cleanly and advise on whether the cylinder needs replacing.
Will the locksmith have to drill my lock or damage my door?+
In the majority of broken key situations, no drilling is necessary. A skilled engineer will attempt extraction using precision hook and extractor tools first, and this succeeds in most cases on standard nightlatches and euro cylinders. Drilling is only considered when extraction is genuinely impossible — for example, when a key fragment is deeply lodged in a 5-lever mortice deadlock and cannot be hooked. Even then, a trained engineer drills in a controlled way that targets only the lock cylinder, not the door itself, and a new cylinder is then fitted. The aim is always to leave the door in at least as good a condition as we found it.
How much does it cost to get a broken key extracted?+
There is no single fixed price because the job varies considerably depending on factors such as the type of lock (nightlatch, mortice deadlock, multipoint euro cylinder), how the key has broken and where the fragment sits, whether the cylinder needs replacing afterwards, the grade of any replacement parts, the time of day (evening, weekend, or bank holiday call-outs are priced differently), and travel distance. What we always do is confirm an exact, agreed price with you on the phone before anyone comes out, so you know exactly what you are committing to. There are no hidden charges added at the end of the job.
My key broke and now I cannot lock the door at all — is that a locksmith job or should I call someone else?+
That is very much a locksmith job, and it is worth treating as urgent — a door you cannot lock is a security risk, particularly overnight. When a key breaks inside a multipoint euro cylinder (common on uPVC and composite doors), the locking cam can be left in an intermediate position that prevents the door from fully locking or even from closing properly. Our engineers deal with this regularly on uPVC doors across the Kentish Town area and can usually resolve it in a single visit — extracting the fragment, assessing the cylinder, and fitting a replacement if needed. Call us on 020 7871 7825 and we will send someone straight away; we are usually with you in about 30 minutes.
