The call almost always comes at the worst moment — locked out in the cold, a key snapped off in the door, a lock that has finally given up. You are stressed, you want it fixed now, and you are in no position to shop around. That is precisely the moment a small number of operators in this trade are built to exploit. They are not really locksmiths in any meaningful sense; they are a sales operation that happens to carry a drill. This guide explains exactly how the scam works, the warning signs that give it away, and what to do — before, during and after — so the worst day does not also become an expensive one.
It is worth saying plainly why this is even possible: locksmithing in the UK is not regulated by the government, so anyone can call themselves a locksmith with no training and no checks. We cover what that means in full in our guide to locksmith accreditation. The practical upshot is that the badge on the van tells you nothing — so you have to know what to look for.
How the rogue locksmith scam actually works
Nearly every case follows the same script, known in consumer-protection circles as bait and switch. The bait is a strikingly low price in an online advert or at the top of a search — very often £39, £49 or £59. You call, reassured by the number. What you have usually reached is not a local locksmith at all but a national call centre that farms the job out to whoever is nearest. The person who turns up has every incentive to inflate the bill, because the headline price was never the real one.
On arrival, the job is suddenly "more complicated than it sounded." The lock, they say, will have to be drilled — destroying it and conveniently creating an instant parts sale. A replacement cylinder appears from the van at several times its retail price. Labour is added at a rate never mentioned on the phone. The £49 call leaves as a bill of several hundred pounds, sometimes accompanied by pressure, a refusal to leave, or a quiet instruction not to tell anyone.
This is not a rare horror story. The Master Locksmiths Association — the trade's largest body, which tracks these complaints — has reported that scam locksmith reports rose by around two-thirds between 2021 and 2025. Consumer group Which? has documented victims charged anywhere from several hundred to several thousand pounds for a single emergency call-out, with one widely reported case reaching roughly £1,800 for a straightforward lockout.
The warning signs, before and at the door
You can spot almost every rogue before they ever touch your lock. Treat any of these as a reason to stop and think twice:
- A suspiciously cheap headline price. An advertised £39–£59 "from" price is the single most reliable signature of the scam. Real work rarely costs that, and the figure exists only to get you to call.
- A call centre answers, not a person. If you cannot get the name of the actual locksmith coming out, or the company's address, you are likely talking to a lead-broker subcontracting the job.
- They will not commit to a price. A fair locksmith gives a fixed all-in figure, or a tight range confirmed before any work. Vagueness on the phone becomes a shock on the invoice.
- Drilling is the first suggestion. A trained locksmith opens most doors without damage. Reaching for the drill straight away is the most profitable move for someone with no skill — not the right one.
- An unmarked van and no paperwork. Professionals tend to arrive in branded vehicles and provide a receipt. No livery, no invoice and no company details are all telling.
- "You can claim it back on your insurance." This reassurance is used to soften an outrageous bill. As we explain in our guide to locks and home insurance, a standard lockout usually is not covered at all.
- Pressure, intimidation or "don't tell anyone." Standing over you while you pay, or discouraging you from getting a second opinion, is the behaviour of someone who knows the price is indefensible.
The fastest test there isBefore anyone sets off, ask for a fixed, all-in price including parts and VAT. A professional will give you a number. A rogue will give you a reason they cannot — and that answer tells you everything you need to know.
What to do before you let anyone out
A few minutes on the phone is your best protection. Ask for the company's full name and address, then check that the website you found actually matches who they say they are — scam adverts often borrow the look of a genuine local firm. Ask for a total fixed price including parts and VAT, and if you can, send a photo of the door and lock so the quote is realistic. Read the one-star reviews specifically, not the glowing five-star ones at the top, which are easily faked.
One more thing worth knowing: simply asking for a quote is not the same as booking a job. Trading Standards teams have warned of cases where someone rang only to enquire about cost, and a locksmith turned up uninvited and demanded a call-out fee anyway. If you do not like what you are hearing, end the call, do not share your card details, and make it clear you are not engaging their services.
Why "we'll have to drill it" is usually the tell
A properly trained locksmith opens the large majority of domestic locks non-destructively — picking, bypassing or manipulating the mechanism rather than wrecking it. We explain how that is done in how locksmiths open locked doors. Drilling is a genuine last resort for a failed or high-security lock, not an opening move. Because it needs no skill and forces a parts sale, it is the rogue's favourite first step. If drilling is proposed in the first couple of minutes on a standard lock, ask why — and do not be afraid to stop the job. Our UK price guide sets out what fair work actually costs.
If you have already been overcharged
First, do not be bullied into paying more or signing anything on the spot. If you feel physically threatened, that is a police matter — call 999. Otherwise, gather your evidence while it is fresh: photograph the lock and any damage, keep the invoice and a screenshot of the original advert or quote, and note times and names. Paying by card rather than cash matters, because it gives you a route to dispute the charge with your bank afterwards.
You are not without recourse. Many people have successfully recovered part of an inflated bill by writing to the firm setting out what a fair price would have been and what they are prepared to pay. A genuine independent locksmith can tell you what the job should have cost, which strengthens your case.
How to report a rogue locksmith
Reporting matters even if you recover nothing, because it is how these operators are eventually stopped. In the UK the main routes are:
- Citizens Advice consumer service on 0808 223 1133 — this is the official first port of call, and it passes reports to Trading Standards.
- Action Fraud (actionfraud.police.uk) if you believe you have been defrauded rather than simply overcharged.
- The police — 999 if you are threatened at the time, or 101 afterwards.
- An honest review, which warns the next person who searches the same name.
Credit where it is due: the Master Locksmiths Association also records pricing complaints about its approved members and will investigate them, and its consumer guidance has done a great deal to raise awareness of this problem.
How to make sure it never happens to you
The single best defence is to choose your locksmith before an emergency forces the choice on you. Find a genuine local business now, save the number, and you will never have to gamble on a search result at midnight. When you do, look for the things a rogue cannot fake: a real local presence, a fixed price quoted up front, a nationally recognised qualification and a DBS check — the full checklist is in our guide to choosing a locksmith you can trust, and the credentials that separate professionals from the rest are explained in locksmith accreditation.
Every LocksmithLocal locksmith works the opposite way to the script above: a fixed price agreed before any work begins, no call-out fee at any hour, non-destructive entry wherever possible, and insurance-rated parts at honest prices. If you would like a trusted number saved for the day you need it, find your local locksmith — so the worst day stays just a bad day.
