Broken Key Extraction
A snapped key lodged inside a lock is one of those problems that tends to happen at the worst possible moment — returning home late to a flat on Well Hall Road, or stepping out early for work and finding the door will not budge because half the key is still in the barrel. The break almost always happens inside the lock body itself, which means the remaining stub is recessed, often flush or below the face of the cylinder, nightlatch, or mortice, and standard household tools are likely to push it deeper rather than coax it out. At Eltham Locksmith we handle this situation every day, attending properties across SE9 and the surrounding area.

What sets a skilled extraction apart from a costly mistake is technique, the right tools, and a thorough understanding of how each lock type is constructed. Our trained, insured technicians work on the principle of causing no additional damage to the lock or the door — in the majority of cases the lock itself can be saved and the homeowner simply needs a new key cut from the remaining working half. This page explains what we do, why the lock type matters, and how to reach us around the clock on 020 3757 5833.

Why Keys Snap — and Why It Matters Which Lock You Have
Keys break inside locks for a handful of predictable reasons: metal fatigue from years of use, a lock mechanism that has become stiff or misaligned, forcing a key when the door has dropped slightly on its hinges, or simply a key that was already cracked and nobody noticed. The critical variable for successful retrieval is the lock type, because each one presents the broken fragment differently. A Yale-type nightlatch — the kind found on almost every front door in Eltham alongside the mortice deadlock — holds the key in a relatively shallow rotating barrel, so a fragment that sits proud of the face is accessible with the right extractor hook. A five-lever mortice deadlock, which many insurers require to meet BS3621, grips the broken piece inside a longer, narrower keyway, and the levers themselves can clamp onto the stub if the lock is under any tension. Euro cylinders, standard on uPVC and composite doors throughout the area, are arguably the trickiest: the pin stacks hold the fragment firmly, and the keyway profile varies considerably between manufacturers.
Understanding which lock you have helps our technician arrive prepared. When you call 020 3757 5833 our team will ask a few quick questions — lock type if you know it, whether the key snapped flush or is protruding, and whether the lock was open or closed at the moment of the break. That information lets us send the right specialist with the appropriate extraction kit, so we are not standing on your doorstep improvising.
Broken Key Extraction Without Damaging Your Lock
The goal of professional broken key extraction is to remove the fragment cleanly so the lock continues to function exactly as it did before. Our technicians use a combination of hook picks, jigsaw-style key extractors, and purpose-built spiral extractors sized to match the keyway profile of your specific lock. For a nightlatch barrel the technique typically involves engaging one of the key's cuts with a fine hook and rotating gently to ease the stub out in the same plane it entered. For a mortice lock, releasing any tension on the levers first is essential — pushing the door leaf firmly against the frame before attempting extraction prevents the levers from biting into the brass and scoring the stub further into the keyway. Euro cylinders require matching the extractor width precisely to the keyway opening so as not to collapse the pin stacks downward onto the fragment.
In the majority of residential call-outs across Eltham — from terraced houses off Shooters Hill Road to ground-floor flats with communal entrances on the Ferrier Estate — we complete the extraction without drilling, without destructive entry, and without needing to replace the lock at all. Where the broken piece has been forced further in by a previous attempt, or where the lock was already failing mechanically, we will advise you honestly about whether a lock replacement is the more practical outcome. We never recommend unnecessary work, and we confirm an exact up-front quote before any work begins.
What Happens After the Fragment Is Out — Emergency Locksmith London Response
Once the broken stub is removed the lock is tested through its full range of movement. If it passes, the homeowner simply needs a replacement key cut from the other half — we do not cut keys ourselves, but we will tell you exactly what to take to a key-cutting service and check the new key turns smoothly before we leave. If the lock has suffered internal damage — worn levers, a cracked cylinder body, or a cam that no longer sits true — we carry a range of replacement euro cylinders and can often fit a like-for-like unit the same visit. Where a door has a mortice deadlock that needs replacing, we work to current British Standards and can advise on anti-snap euro cylinders and TS007 3-star rated products for uPVC doors, which are worth considering given that cylinder-snapping attacks are a documented method of forced entry in southeast London.
As a 24 hour locksmith London service we respond to broken key call-outs at any hour — including evenings, weekends, and bank holidays. We send a technician straight away and are usually with you in around 30 minutes, though travel time varies depending on where in or around Eltham you are located. The call-out charge, the labour involved, and whether any parts are needed are all explained clearly on the phone before anyone sets off — the quote we give is the price you pay.
Factors That Affect the Cost of Broken Key Extraction
We are often asked how much it costs to get a snapped key out, and the honest answer is that it depends on several things we assess before confirming a figure. The lock type is the first factor: a nightlatch extraction on a standard pin-tumbler barrel is straightforward; a high-security five-lever mortice or a mul-t-lock euro cylinder takes more time and specialist tooling. The time of day matters — evening and bank holiday call-outs reflect the genuine cost of mobile availability around the clock. Travel distance from our nearest available technician to your address in SE9 or the surrounding area plays a role, as does whether the extraction alone resolves the problem or whether a replacement cylinder or lock case is also needed.
What we commit to is transparency: when you call 020 3757 5833 we ask the questions we need, work out what is involved, and give you an exact figure before we dispatch anyone. There are no surprise additions when the job is done. We never use vague language about pricing and we do not ask you to agree to work on trust — the quote is fixed and clear from the outset.
Frequently asked questions
Can you get a broken key out without replacing the lock?
In most cases, yes. If the fragment is extracted cleanly and the lock mechanism has not suffered damage from the break or from previous attempts to remove the key, the lock can continue to be used as normal. We test it fully before we leave. A lock replacement is only recommended when the internal components are worn, cracked, or no longer functioning correctly — and we will always explain why before proceeding.
The broken piece is completely flush with the face of the cylinder — does that make it harder?
It does make it more challenging than a stub that is protruding, but it is a situation we deal with regularly. A flush or recessed fragment in a euro cylinder is typically handled with a spiral extractor or a very fine hook pick matched to the keyway profile. It takes patience and the right tool — which is exactly why attempting it with a paperclip or a thin screwdriver often makes things worse by pushing the fragment deeper or scoring the inside of the barrel.
Someone has already tried to get the key out and may have pushed it further in. Can you still help?
Yes, though it may take a little longer. When a fragment has been pushed beyond the standard retrieval zone — past the first pin stack in a euro cylinder, for example — we use longer extraction tools and sometimes a small amount of lubricant to ease it back. In a small number of cases where the fragment is irretrievably deep and the lock cannot be operated, a controlled cylinder replacement becomes the practical solution, which we can carry out the same visit.
My front door has both a nightlatch and a mortice lock and the key snapped in the mortice. Will I be locked out of the flat completely while you work?
Not necessarily. If the nightlatch is operable and the door can be held on the latch, you may be able to stay inside or allow access while we work on the mortice from outside. If both locks are engaged and you are locked out, we will gain access via the safest available method — usually the nightlatch — before addressing the mortice extraction. We always look for the least disruptive approach first.
How do I know the person arriving is a genuine, qualified locksmith and not someone who could take advantage of the situation?
Our technicians are trained, experienced, and insured. When you book with us on 020 3757 5833 you will be given the name and an approximate arrival time for the technician heading to you. We will also confirm the exact price on the phone before dispatch, so you know precisely what has been agreed before anyone arrives at your door. If you have any concerns at the door, ask to see identification before allowing entry — any professional technician will expect that and have no issue with it.
Does the time of day affect how quickly you can reach me in Eltham?
We operate 24/7, including through the night, at weekends, and on bank holidays, so there is always a technician available. We send someone straight away and are usually with you in around 30 minutes. Late-night or early-morning call-outs in SE9 and the surrounding area are a routine part of what we do — if anything, traffic is lighter at those hours, which can work in your favour.
