Locksmith Scams in the UK: How to Hire One Safely

By UKListingz Editorial Team Published 6 November 2026 Updated 6 November 2026 11 min read

Locksmith scams in the UK usually follow a familiar pattern: a very low price over the phone, a sudden jump in the bill on arrival and pressure to pay before you can think. The safest way to hire a locksmith is to check the business before you need one, insist on a total price in writing, and refuse work that starts without an agreed figure. Urgency is what the scam relies on.

Key takeaways

• Be wary of a call-out price that sounds unusually cheap, and ask for the total including call-out, labour, parts and VAT.
• A genuine locksmith will explain the options before drilling anything, because a lock can often be opened without destroying it.
• Check that the name on the van, the invoice and the website match, and look for a landline and a trading address.
• Check membership of a trade body such as the Master Locksmiths Association, using its own website.
• Never sign a blank form or agree to pay by cash on the doorstep without a receipt.
• If you feel pressured or threatened, stop the work, pay only what was agreed and report it to Trading Standards or Citizens Advice.

How do locksmith scams usually work?

Most locksmith scams share the same core tactic: they make a low offer to win the job, then add charges once the locksmith is on site and you have little choice. The offer may come from a search result, a leaflet pushed through the door or a number that appears to be local. The locksmith who arrives may not be the person you expected, and the price may change several times before the work is finished.

The low advertised price

An advertised price that looks too good is the most common hook. The figure may cover only the first few minutes of the visit, or it may apply only to a standard lock on a standard door. Anything else, such as a euro cylinder, a night visit, a multi-point lock or a replacement key, can be priced much higher once the locksmith is there. Ask what the advertised figure does and does not include, and whether the total is fixed.

Scams often use names that sound local, and some appear near the top of search results for only a short time. Some firms take the call and then pass the job to a subcontractor, who may charge differently from the figure you were quoted. Ask who will attend, and whether the business that answered the phone is the one that will send the invoice.

Drilling, replacing and upselling

Some scam locksmiths go straight to drilling or replacing the lock, because it is faster and more profitable than opening the existing one. Ask the locksmith to explain what they plan to do, and why. A good locksmith will usually try to open the lock without damage first, and will tell you if the lock must be replaced. Ask to see the replacement part and keep the old one if you can, because it helps show what was done.

Pressure and threats

Pressure tactics are the clearest warning sign. A locksmith who says the price will go up if you do not decide now, who refuses to write anything down or who suggests your belongings will be kept until you pay is behaving badly. Stay calm, do not hand over money on the spot without a written price, and call someone you trust. If you feel unsafe, call the police on 999 in an emergency.

What should you check before you need a locksmith?

The best time to check a locksmith is before you are locked out. Keep a saved, verified number for a reputable local firm in your phone, and check it occasionally. When you do need an emergency locksmith, you will have some basic checks you can run quickly.

• Search for the business name and read its website, looking for a full trading address and a landline number.
• Compare the name on the website with the name on the van, the invoice and any business card you are given.
• Check trade body membership on the trade body's own website, not from a logo on the locksmith's materials.
• Read reviews with care, looking for patterns of similar complaints about price changes or drilling.
• Be cautious of firms that answer with a generic name or a mobile number only, with no way of checking who they are.

The Master Locksmiths Association is the trade body most relevant to locksmith work in the UK. Membership can give you a route to raise a complaint, but it does not guarantee the price or the quality of every job. UKListingz lists businesses by category and town and does not verify qualifications, insurance or accreditation, so you need to make these checks yourself. You can browse locksmiths by town to see several options before you need one.

How do you agree a price before work starts?

A fair price is one that is stated in full before the work begins. Ask the locksmith to confirm the total cost in writing, including the call-out, the labour, any parts and VAT, and any extra charge for an evening or weekend visit. A simple email or text message is better than nothing, but a written quote on company letterhead is better still.

Ask what happens if the lock cannot be opened without damage, and ask whether a replacement will be needed. Agree that the locksmith will stop and call you before drilling, and that any extra cost will be explained first. If the locksmith refuses to put any of this in writing, the safest response is to find someone else.

Lock type affects the price, so ask the locksmith to name the lock they are dealing with before quoting. A standard cylinder, a mortice lock, a multi-point lock on a uPVC door and a high-security cylinder each need different skills and parts. A good locksmith can tell you which one you have and why it matters, and will explain the difference in plain terms.

After the job, ask for an itemised invoice that matches the quote. Check it carefully before you pay. If the figure is higher, ask why, and ask for the difference to be explained in writing. Keep the invoice, the quote and any messages together.

If you paid by card, check that the amount on your statement matches the invoice. Any difference should be raised with the locksmith first, and then with your card provider if it is not resolved. Keeping the paperwork in one folder, paper or digital, saves time if you ever need it.

Which warning signs should make you walk away?

Some signs are red flags on their own, while others only become clear when they appear together. The table below sets out common warning signs and a practical response to each. If you see more than one, stop and find another firm.

If you have already paid a deposit or made a payment, keep records of the card or bank transaction, the date and the business name you were given. Card payments can give more protection in some circumstances, which is covered later in this guide.

A short note written on the same day, while the details are fresh, is often the most useful record you can make.

What should you do if you are already locked out?

Being locked out is stressful, and it is exactly when scams work best. The following steps can help you stay in control while you find a genuine locksmith. They are general steps, not a substitute for emergency services if someone is at risk.

1. Check whether you can get in safely another way, such as an open window you can reach without risk, or a spare key held by a neighbour or family member.
2. If a child or vulnerable person is inside, or there is any risk to safety, call 999.
3. Search for a locksmith and ignore any firm that will not give a full name, address and total price before arriving.
4. Ask for the price to be confirmed in writing by text or email, including the time of arrival and the work to be done.
5. When the locksmith arrives, ask to see identification and check the name matches the quote.
6. Agree that no work will start until you have confirmed the price, and do not sign anything blank.

If your lock is damaged in an emergency, the guide to who to call for a home emergency sets out the broader options, including your home insurer's helpline, which can sometimes arrange a locksmith.

If you are renting, let your landlord or letting agent know as soon as you can, because tenancy arrangements can place responsibility for locks and keys in different ways. Keep a written note of the time you called, the firm you used and the price agreed. That record is useful whether you are dealing with an insurer, a landlord or Trading Standards later on.

What are your rights and where can you report a bad locksmith?

Under the Consumer Rights Act 2015, a locksmith must carry out the service with reasonable care and skill. Where no price was agreed, you should pay a reasonable price, and where no time was agreed, the work should be done within a reasonable time. If work is not done properly, you can ask for it to be put right or for the price to be reduced. These are general principles, and the details depend on what was agreed.

If you believe you have been misled about the price, or treated unfairly, you can seek advice from Citizens Advice through its consumer service. Trading Standards enforces consumer law locally, so it is the right body to contact about misleading pricing or aggressive behaviour. Keep your evidence, including the advert, call records, quote, invoice and any messages.

Do not be afraid to refuse. A reputable locksmith will accept a reasonable refusal to pay for work you did not agree to, and will usually explain the situation calmly. If the locksmith becomes aggressive, or tries to hold your property until you pay, leave the situation if it is safe to do so, and call 999 if anyone is at risk. The guide to complaining about a business sets out the steps to take next.

Paying by credit card can offer extra protection. Section 75 of the Consumer Credit Act 1974 can make the card provider jointly liable for purchases costing between £100 and £30,000, subject to conditions. Most locksmith bills are below £100, so this may not apply to your situation. Ask your card provider about the options for your payment.

What should you do next?

Use the checklist below to protect yourself the next time you need a locksmith, whether it is an emergency or a planned change of lock. Keep the list somewhere easy to find, and share it with anyone in your household.

• Save the number of a verified local locksmith in your phone before you need one.
• Check the business name, address and trade body membership on independent sources.
• Ask for the total price, including VAT and any out-of-hours charge, in writing.
• Ask the locksmith to explain the work before any drilling or replacement.
• Pay by a traceable method and keep the invoice and the receipt together.
• Report misleading or aggressive trading to Trading Standards, and seek advice from Citizens Advice.

When you are ready to compare firms, UKListingz lets you browse locksmiths by town, and you can also look at security companies if you want advice on upgrading your locks. The guide to spotting a rogue trader covers more warning signs that apply across the trades.

If a firm has already taken money and will not explain the work, the next step is to put your concerns in writing and keep a copy.

Frequently asked questions

Why are locksmith prices so different between companies?

Prices vary because locksmiths work in different ways, with different levels of experience, insurance, equipment and call-out arrangements. A low price can mean a fair service with a clear total, or it can mean the bill will rise later. The useful comparison is the total price for the same work, confirmed in writing.

Can a locksmith legally drill my lock without asking me?

A locksmith should not carry out work you have not agreed to. If the lock cannot be opened without damage, a good locksmith will explain the options and ask for your approval before drilling or replacing it. If you have not been asked, refuse the work and ask for the explanation in writing before anything else is done.

What should I do if the locksmith asks for more money than agreed?

Ask for the reason in writing and for the new total before you agree. Compare the new figure with the original quote and ask which item has changed and why. If the answer is unclear or the locksmith insists on payment on the spot, pay only what you agreed and report the issue to Trading Standards or Citizens Advice.

Is it safe to pay a locksmith by cash?

Cash is not always unsafe, but it makes it harder to prove what you paid and when. Ask for a receipt that shows the business name, the date, the work done and the amount paid. A traceable payment method gives you a clearer record if you need to dispute the bill later.

Can I cancel a locksmith booking?

The Consumer Contracts Regulations 2013 generally give a 14-day cancellation period for contracts agreed away from the trader's premises, such as at your door, or online or by phone. If you ask for work to start within that period, you may have to pay for work already done, and rules differ for emergency repairs you ask for. Check GOV.UK for the current position.

How do I know if a locksmith is a scam or just expensive?

A scam usually involves a price that changes without explanation, pressure to pay immediately, refusal to put terms in writing or unnecessary drilling. An expensive but honest locksmith will explain their charges, give you a written total and let you make the decision. If you are unsure, pause the work and seek advice before you pay.
