Locked out right now? Our emergency locksmith team is already moving.
You don't need a lecture on lock-snapping technique. You need someone at your door. The Lock Specialist Ltd dispatches a real, DBS-checked engineer — not a call centre reading a script — 24 hours a day, every day of the year, across London.
Free survey and no call-out charge. Nothing starts until you have agreed to it.
- We dispatch our own engineers, never a call centre
- Nothing begins until the survey is explained
- Non-destructive entry attempted first
- Written detail for your insurer
Call 020 8261 7495 — the line is answered by an engineer, day or night.
What we treat as an emergency
Everything below is dispatched immediately, at any hour. You do not need to justify the call or wait until morning.
You cannot get in
Keys inside, keys lost, the door slammed behind you, or a lock that has stopped turning altogether.
You cannot get out
A mechanism that has seized while locked. This is treated as the highest priority because it is a fire-safety issue, not an inconvenience.
The door will not lock
You can get in, but the property cannot be left secure. Same urgency — an unsecured door overnight is the real risk.
Break-in or attempted entry
Forced door, snapped cylinder, damaged frame. The priority is making the property secure tonight.
A key snapped in the lock
Blade still inside the cylinder, door unusable. Extraction first, then the reason it snapped.
Keys lost or stolen
Particularly where something on the keyring could identify the address. Entry first, then a decision about the lock.
Lock jammed solid
Key will not go in, will not turn, or turns without moving anything. The door is unusable in whatever state it is currently in.
Latch will not catch
The door swings back open, or has to be held shut. Common after a frame drops, and it leaves the property unsecured.
A business cannot open or close
Shopfront, office, fire exit, shutter or grille. Attended around trading hours, including before opening.
A communal door has failed
Residents locked out of a block, or a main entrance that will not secure. We check the key suite before touching anything.
Any of those describe your door right now?Call and you will have an arrival time before you hang up.
What happens from the moment you call
- An engineer answers, not a dispatcher. We ask what the door is, what the lock looks like and what the fault is doing. That decides which engineer and which parts come to you — which is why the first call is short and specific rather than a script.
- You are given an arrival window. Based on your area and the nearest available engineer. Typically 20–40 minutes across most London postcodes. You get the estimate on the call, and you are told if it changes rather than left waiting.
- You are kept updated until we arrive. You receive a call with an ETA and are updated through to arrival. Standing outside at 2am with no information is the actual complaint most people have about this trade.
- Free survey on arrival. The door and lock are inspected, the fault identified and the options explained before anything is dismantled. No call-out charge, and nothing starts until you agree.
- Non-destructive entry first. We pick and manipulate where the mechanism allows, so in most cases your existing lock survives the visit and there is nothing to replace.
- The property is left secure and tested. The lock is tested closed, not just open — which is where most callbacks come from. Parts carry a 180-day warranty, and you get written detail of what was wrong and what was done.
Is it an emergency, or can it wait until morning?
Worth knowing, because calling at 2am for something that could wait costs you a broken night, and waiting until morning with something urgent can cost you a lot more than that. The dividing line is simple: can the property be left secure, and can everyone get out.
Call now
- Locked out with no other way in
- Door will not lock and you are leaving or sleeping there
- Mechanism seized while locked and nobody can get out
- Break-in or attempted forced entry
- Keys lost and something on the ring identified your address
- Key snapped and the door cannot be secured
- Commercial premises that cannot be locked overnight
Can wait — book a repair
- Locked out but a neighbour or family member has a spare
- Key stiff or needing a jiggle, but still working
- uPVC handle needs lifting, door still locks
- Barrel stands proud of the handle plate
- Window handle loose or a stay that no longer holds
- Second lock or upgrade you have been meaning to fit
The right-hand column is still worth acting on soon rather than never — most emergency callouts we attend began as a small fault someone lived with for weeks. If you recognise your door there, the causes and fixes are set out on London lock problems explained, and a planned lock repair or an upgrade fitted properly is a far easier visit than a 3am one.
What to do while you wait for us
Most of this is about not making the job harder or less safe before we get there.
- Stop trying the key. If it is stiff, every extra turn brings it closer to snapping inside the cylinder — which turns a lockout into an extraction job.
- Do not force the handle on a uPVC door. A gearbox that is failing will fail completely under force, and then the door has to be opened before it can be fixed.
- Wait somewhere safe, not on the doorstep. A café, a neighbour, your car. Tell us where you will be and we will call when the engineer is close.
- Have proof of residence ready if you can. ID, a bill on your phone, a tenancy document, or a landlord who can confirm by phone. It saves time on arrival.
- After a break-in, photograph the damage before anything is touched. Your insurer will want it, and so will the police if you report it.
- Do not let anyone else "have a go" at the lock. A drilled or damaged cylinder removes the option of opening it non-destructively, which usually means paying for a replacement that was not needed.
- Keep your phone reachable. The engineer calls with an ETA and again on approach, particularly for flats and communal entrances.
One thing not to do: the online tutorials about carding a latch or bumping a cylinder. They damage the mechanism far more often than they open it, and on a door you have to keep using that is an expensive twenty minutes.
Already outside your door?Stop reading and call — we will talk you through it on the phone.
Why we arrive when we say we will
Arrival time in London is a traffic problem, not a driving problem. Two things make the difference:
- Motorbike-mounted engineers. Emergency engineers are assigned bikes so they can move through traffic that stops a van — which matters most at exactly the times emergencies happen, rush hour and closing time.
- Engineers distributed across London, not dispatched from one depot. The engineer sent to you is the nearest one, so an E1 callout is not being served from south London.
We give an honest window rather than a flattering one. If an engineer is 35 minutes away you will be told 35 minutes, because a missed promise at 2am is worse than a realistic one.
Emergency services we attend
Every one of these is dispatched immediately, at any hour. Each has its own page with the detail specific to that job.

What London customers say
These come straight from our Google profile, unedited. You can open any of them yourself rather than taking a screenshot on a website at face value.
Getting you in without wrecking your door
The single biggest difference between locksmiths is what they reach for first. Drilling is fast and needs little skill, and it guarantees a replacement lock is sold. Picking takes skill and takes longer, and it usually leaves you with the lock you already had.
We pick and manipulate first, on every job where the mechanism allows it. Drilling is reserved for the cases where it is genuinely the only route — a cylinder already failed internally, a lock deliberately hardened against picking, or a mechanism seized solid. When that is the situation you are told before it happens, not after.
If you are trying to work out what has actually failed on your door, that is covered in detail on London lock problems explained.
After a break-in
This is the call we treat most carefully, because you are dealing with the aftermath before you are dealing with the door.
- Tonight: make it secure. Boarding where glass or a panel has gone, temporary locking where the mechanism is destroyed, and a door that closes and locks before we leave.
- Written detail for your insurer. What was damaged, how entry was made, what was fitted. Provided as standard — a claim is much harder without it.
- Permanent repairs once you have spoken to them. No pressure to decide about upgrades at 3am. Those decisions are better made in daylight, and your insurer may specify what goes back on.
- Then the weak point. Once things are calm, the entry point is worth reviewing — because forced entry almost always exploits something specific rather than being random.
Police reference numbers, if you have one, are worth having to hand — insurers usually ask.
Been broken into tonight?We will secure the property first and put the detail in writing for your insurer.
Nights, weekends and bank holidays
Cover runs 24 hours a day, every day of the year. There is no separate out-of-hours number and no answering service taking a message for the morning — the same line reaches an engineer at 3am on a Sunday as at 11am on a Tuesday.
In practice most emergency calls come in three clusters: late evening when people get home, early morning when people leave, and Sunday nights. Cover is staffed around that, which is why a bank holiday callout is not slower than a weekday one.
Three calls we take most weeks
Written out because "we attend emergencies fast" tells you nothing about what actually happens. These are the shapes the work usually takes.
Flat door, keys inside, 11pm
A nightlatch has closed behind you. On the call we establish it is a communal entrance plus a flat door, which means access to the building has to be arranged first — a neighbour, an intercom, or the engineer meeting you at the main door. The flat door itself is usually picked open in minutes and the lock keeps working, so there is nothing to replace. See locked out.
uPVC door will not lock, Sunday evening
You are inside, the handle has gone soft, and the door will not secure for the night. This is almost always the multi-point gearbox rather than the barrel. Common gearboxes are carried in the van, so most are replaced on the same visit and the door, frame and glass are untouched. Where the exact unit is not on board, the door is made secure overnight and finished the next day. See emergency lock repairs.
Forced front door, discovered on arriving home
The priority is not the lock, it is a door that closes and locks before we leave. Boarding where a panel or glass has gone, temporary locking where the mechanism is destroyed, and written detail of the damage for your claim. Upgrades and permanent repairs are decided in daylight, once you have spoken to your insurer — not at 3am while you are still taking it in. If you want to understand what was exploited, that is covered under lock snapping and anti-snap cylinders.

Where to go next
If your situation is more specific than "emergency", these go straight to it:
- Locked out of your home or flat — non-destructive entry, including communal doors
- Keys lost, stolen or never returned — entry first, then whether the lock needs changing
- A door that will not secure — emergency lock repairs and break-in damage
- Emergency locksmith for a house — houses, flats and HMOs
- Business premises locked out or unsecurable — shopfronts, offices and fire exits
- Round-the-clock cover — how 24/7 actually works here
- Book a repair instead of an emergency — for faults that have not stranded you yet
- Have a new or additional lock fitted — including to insurance requirements
Two guides worth ten minutes when things are calm:
London lock problems explained — what stiff keys, spinning barrels, floppy handles and snapped keys actually mean, and whether each one is a repair or a replacement.

Emergency locksmith questions
How fast can an emergency locksmith reach me in London?
Typically 20–40 minutes across most London postcodes. You are given an estimate on the call based on your area and the nearest engineer, then updated if it changes. Rush hour and the far edges of Greater London sit at the longer end of that.
Are you actually available at 3am?
Yes. The same number reaches an engineer at 3am as at midday, including weekends and bank holidays. There is no separate out-of-hours line and no message service taking details for the morning.
Is there a call-out charge for an emergency?
No. The survey is free and there is no call-out charge, including at night. The fault is diagnosed and explained before any work begins.
Will you have to drill my lock to get me in?
Usually not. We pick and manipulate first, so the existing lock most often survives the visit. Drilling is reserved for mechanisms that have already failed internally or are hardened against picking, and you are told before it happens rather than after.
What do you need to know when I call?
What the door is made of, roughly what the lock looks like, whether it is a flat, house or communal entrance, and what the fault is doing. That determines which engineer and which parts are sent, so those thirty seconds save time on site.
I am locked out with no ID on me. Can you still help?
Yes, but proof of residence is asked for before the door is opened. That may be ID, a bill, a tenancy document, or confirmation from a landlord or agent. It protects you as much as us — a locksmith who opens any door on request is a liability to everyone on the street.
My door will not lock but I can get in. Is that urgent?
Yes, and it is treated with the same priority as a lockout. A property that cannot be secured overnight is the greater risk, even though it feels less dramatic than being stuck outside.
Can you secure my home tonight after a break-in?
Yes. The priority is a door that closes and locks before we leave, using boarding or temporary locking where the mechanism is destroyed. Permanent repairs follow once you have spoken to your insurer, and we provide written detail of the damage and the work for the claim.
Do I need a police reference number first?
No — call us first and secure the property. But if you already have a crime reference number, keep it to hand, because insurers normally ask for it alongside our written detail.
Can you attend a communal door in a block of flats?
Yes. We check first whether the building runs a suited or restricted key system, because fitting the wrong cylinder to a communal entrance can break access for every resident on the stairwell. Where the freeholder or management company needs to authorise work, we will tell you.
Do you cover commercial emergencies?
Yes — shopfronts, offices, restaurants, fire exits, shutters and grilles, including before opening and after closing so trade is not interrupted.
What if the emergency turns out to be a simple repair?
Then that is what you are told and that is what is done. The survey exists to establish what the job actually is, and a misaligned keep that needs adjusting is not turned into a lock replacement.
