How do you recognise a fake locksmith in Paris?

Beware of prices that are too low on the phone, no written quote before work, a technician without professional ID, and a vague invoice or one without a SIRET. A real craftsman gives a clear price, an address, a certification (RNCP) and leaves a detailed invoice.

What should I do if I have been scammed by a fake locksmith?

Keep all documents (quotes, invoices, SMS), take photos of the work and parts fitted, then file a complaint with the police or gendarmerie. Also report the company to the DGCCRF and contact your home insurer. A certified locksmith can then check and, if needed, redo the work.

Does 247 Serrurerie display its rates in advance?

Yes. At 247 Serrurerie, base rates are public (slammed-door opening from €120 incl. VAT, high-security cylinder from around €220 incl. VAT). A clear quote is given before any intervention, and a detailed invoice is provided for your insurance.

Fake Locksmiths in Paris: How to Avoid Them

Every year in Paris, hundreds of people fall for fake locksmiths: inflated prices at the end of the job, unnecessary parts fitted, or ghost companies that vanish after payment. In an emergency — slammed door, broken key, break-in attempt — stress pushes people to accept the first number they find. Here is how to avoid the scam and choose a real professional.

Why Paris is a prime target

Apartment density, tourism and the volume of emergency calls make Paris ideal ground for scammers. They buy sponsored ads, impersonate real company names, or present themselves as insurance “partners”. The classic scenario: a low price on the phone, then a multiplied invoice once the door is open.

Warning signs to know

Before confirming an appointment, check these points:

Price too low or too vague: “from €39” for an opening, with no detail on the final package
No written quote before starting (SMS, email or paper quote)
No SIRET, clear address or professional website
Pressure: “we’re just around the corner, we’ll be there in 5 minutes” with no price confirmation
Cash only, with no detailed invoice
“Mandatory” cylinder change even though the door opens normally

A serious craftsman has no interest in trapping you: their reputation and certifications (RNCP, A2P) are their capital.

The right reflexes in an emergency

Even under stress, take 60 seconds:

✓Ask for the price incl. VAT before travel and what it includes (opening only, or opening + parts)
✓Check the company name and SIRET (website, Google, Infogreffe)
✓Demand a quote before any work
✓Refuse to pay until you have an invoice with full contact details
✓If in doubt, call a second professional to compare

See our locksmith rates for realistic price ranges in Paris: slammed-door opening from €120 incl. VAT, high-security cylinder from around €220 incl. VAT.

How to choose a reliable locksmith

Prefer:

✓An RNCP certification (recognised professional title)
✓Displayed rates and a quote before intervention
✓A clear service area (Paris and Île-de-France)
✓Consistent customer reviews, not only 5/5 scores with no detail
✓An invoice usable for home insurance

247 Serrurerie is a locksmith craftsman in Paris and Île-de-France, available 24/7, with a target arrival time of under 30 minutes in the Île-de-France region. Our technicians introduce themselves, explain the diagnosis, and only start after you agree on the quote.

What to do after a scam?

Keep all evidence (SMS, quotes, invoices, photos)
File a complaint
Report the company to the DGCCRF
Contact your insurer
Have the door and lock checked by a certified professional: poor fitting can weaken your security

If the lock was “replaced” unnecessarily or badly installed, a high-security cylinder change or a door audit may be needed.

Prevention: useful groundwork

Save a trusted locksmith’s number in your phone in advance — as you would for a plumber or doctor. In an emergency, you will no longer have to search at random on Google.

Also check:

✓That the website shows an address and legal notices
✓That reviews mention prices consistent with the Paris market
✓That the company agrees to send a written quote (SMS or email) before departure

A professional eager to “come right away” without discussing price is a warning sign, not a premium service.

Real emergency vs upselling

A slammed-door opening does not systematically require a lock change. If you are told that “everything is shot” while the door opens normally, ask for a technical explanation and a second opinion. At 247 Serrurerie, a cylinder change is offered when it brings a real benefit (wear, security, lost keys) — not to inflate the bill.

In summary

Fake locksmiths thrive on stress and opaque pricing. Demand transparency, a quote and an invoice. At 247 Serrurerie, you know what to expect before the technician arrives.
