In 2024, the DGCCRF inspected more than 600 home repair professionals and found anomalies in over 60% of them, with more than 2,600 reports on SignalConso and 64 criminal reports. These data raise a concrete question: what verifiable criteria can distinguish a reliable locksmith from a problematic service provider even before they arrive?
Mandatory quotes in locksmithing: what the decree of January 24, 2017 states
Most competing pages mention pricing transparency without specifying the regulatory framework. However, the decree of January 24, 2017 imposes strict formalities, even in emergency situations.
The quote must detail the identity of the company, the exact nature of the work, the hourly rate or the fixed price applied, the cost of parts, travel expenses, any surcharges (night, weekend, public holiday), and the total including tax. Urgency does not exempt from this obligation for a detailed quote.
A professional who refuses to provide a written quote before starting, or who presents a vague document without distinguishing between travel, labor, and supplies, sends a clear warning signal. Locksmithing prices are free, which means that a high price is not automatically illegal. However, the lack of prior information on prices constitutes the main offense noted during inspections.
A locksmith service whose amount is increased after initial agreement, or whose invoice does not match the signed quote, falls under misleading commercial practices that can be penalized.
DGCCRF control and concrete warning signals before intervention
The results of the 2024 inspections show that the problem is not limited to a few isolated actors. With an anomaly rate exceeding 60% among the professionals inspected, the home repair sector remains one of the most reported by consumers. Calling on an identifiable and locally established artisan, such as on serrurier-birgel-schmitt.fr, reduces this risk by allowing verification of the company’s actual existence before any intervention.

Before confirming a visit, several checks take less than two minutes:
- The company’s SIRET number must be verifiable on the official business directory (sirene.fr). A locksmith who does not provide their SIRET over the phone or on their quote does not meet their minimum legal obligations.
- Surcharges for night, weekend, or public holiday interventions must be announced before the visit, not at the time of invoicing. The surcharge amount must be included in the quote.
- Payment in cash only, without issuing an invoice, is a recurring marker of fraudulent practices noted by the DGCCRF. A reliable professional offers multiple payment methods and systematically issues a compliant invoice.
Home insurance and locksmith services: a reimbursement often overlooked
Few individuals think to contact their home insurance before looking for a locksmith online. Some contracts include locksmith assistance, with total or partial coverage depending on the subscribed guarantees.
The reflex to adopt: call the assistance number listed on the contract before hiring a service provider found via a search engine. The insurer can either send a partner locksmith directly or reimburse the intervention upon presentation of the invoice, within a limit and after applying any deductible.
Using the assistance from one’s contract has two measurable advantages. The locksmith sent by the insurer is listed and controlled by the partner network. The final cost for the insured is reduced, sometimes to zero if the guarantee covers the incident (slammed door, break-in, lost key according to the contracts).
Comparison of reliability criteria for a locksmith
The table below contrasts compliant practices with warning signals identified during DGCCRF inspections:
| Criterion | Reliable locksmith | Warning signal |
|---|---|---|
| Quote | Detailed, provided before intervention, signed | Absent, oral only or modified after agreement |
| Identification | Verifiable SIRET, physical address | No SIRET provided, PO box only |
| Prices | Surcharges announced in advance, clear total including tax | Price “starting from” without detail, extra charge added on-site |
| Payment | Multiple methods accepted, invoice provided | Cash only, no invoice |
| Announced delay | Realistic estimate based on distance | “15 minutes everywhere” without precise geographic area |

This table summarizes the control points applicable by phone, even before providing one’s address. A locksmith who ticks all the criteria in the “warning signal” column presents a high risk.
Night locksmith services: surcharges and alternatives
Nocturnal or public holiday interventions represent situations where price discrepancies are most pronounced. The surcharge for an intervention outside of working hours is legal, but it must be quantified and communicated before the locksmith’s visit.
Before accepting a night intervention, two options deserve evaluation. If the door is simply slammed without risk to the security of the home, waiting until the next morning for a standard rate intervention can halve the bill.
If the lock has been forced during a break-in, filing a complaint with the police beforehand is recommended. Home insurance often then takes over to organize and finance the repair.
Immediate cash payment under pressure, without a signed quote beforehand, remains the most frequently reported scenario in complaints about abusive practices. Requesting a written quote, even at 2 AM, is a right that the professional cannot refuse.
