What 894 locksmith call-outs in Paris and its inner suburbs tell residents for 2027
From 7 January to 8 October 2026, six family-run locksmith shops in Paris and its inner suburbs logged 894 call-outs. Of these, 390 were slammed doors (43.6%), 214 were cylinder replacements (23.9%) and 120 were doors locked with a key or jammed (13.4%). Together, these three types make up 81% of the register. Slammed doors were logged 1.6 times as often per weekend day as per weekday, but the register as a whole was not busier at weekends.

Slammed door or locked with a key: two different call-outs
In Paris, a porte claquée is a door that has shut behind you and is held only by its latch. The bolt has not been locked with a key. Many apartment doors have no handle on the outside, so once the door has shut it cannot be opened from the landing. A porte fermée à clé has been locked with the key, and the key is lost, stolen or still inside. The register records doors locked with a key and jammed doors as one type.
The register logged 390 slammed doors against 120 doors locked with a key or jammed, about 3.3 slammed doors for each one. Together, these two types account for 510 of the 894 jobs (57.0%).
When you call a locksmith, say which of the two it is. They are different jobs, and the register counts them separately: see the porte claquée and porte fermée ou bloquée pages (in French). Of the six shops, the one with an English-language page is Open Close in Paris 15.
Weekends: more slammed doors, less of everything else
The 275 days covered include 78 Saturdays and Sundays, which is 28.4% of the days. Those weekend days account for 154 of the 390 slammed doors (39.5%). That works out at 1.97 slammed doors per weekend day against 1.20 per weekday, about 1.6 times as many. The pattern holds in each of the three shops with the most slammed-door jobs: 41% of slammed doors fell on a weekend at Start Serrurier, 41% at Open Close and 42% at Serrurerie Centrale. The weekend share is also above the 28.4% baseline at Serrure YES (15 of 40) and Serrure Ouest (11 of 31). Super Serrurier logged too few slammed doors (15) to say.
The other types go the other way:
- Doors locked with a key or jammed: 0.33 per weekend day against 0.48 per weekday.
- Cylinder replacements: 0.47 against 0.90.
- All 894 jobs together: 3.05 against 3.33.
None of the other ten job types was logged more often per day at weekends. So the weekend increase is specific to slammed doors. The register records no causes, so it cannot say why. The French weekday-versus-weekend data note has the breakdown by day of the week. Its charts use day names and numbers, so they can be read without French.
Where the jobs are
Paris accounts for 601 jobs (67.2%), Hauts-de-Seine for 191 (21.4%) and Val-de-Marne for 91 (10.2%). The remaining 11 jobs (1.2%) were in other départements or have no postcode. The areas with the most jobs are the 17th arrondissement (235), Boulogne-Billancourt (159) and the 15th arrondissement (144).
These counts show where the shops are, not where lockouts or break-ins are more likely. For example, Start Serrurier, whose shop is in the 17th, logged 228 of its 302 jobs there (75.5%). Area pages are listed under quartiers (in French).

What this data cannot tell you
- Prices: the register records no amounts, so it gives no average or typical price.
- Time of day: jobs are not timed, so day and night cannot be compared.
- Response times: these are not recorded.
- Causes: there is no burglary category, and cylinder replacements do not record why the cylinder was changed.
- Trends: one partial year gives no year-on-year change and no forecast for 2027.
- Market share or rankings: these are jobs logged by six shops, not all the locksmith work in Paris.
- Completeness: nothing shows that every job was logged, so the figures are recorded call-outs.
Lessons for 2027
- Keep a spare key with someone nearby. In this register, a slammed door was the most frequent call-out: 390 of 894.
- Before you call, check how the door is shut. Has it slammed on the latch, or was it locked with the key? Say which on the phone, because they are different jobs.
- Get a written quote (devis) before any work starts, and keep the invoice (facture). What the law requires: for call-out, repair and maintenance work in the home, the tradesperson must give you price information before you agree to the job, and a detailed written quote before the work starts (for a job agreed at your home, the quote takes the form of the contract). Once the work is done, and before you pay, they must give you a written bill (note), whatever the amount if you ask for one. Source: articles 2, 4 and 5 of the arrêté of 24 January 2017 on price information for home call-out, repair and maintenance work (Légifrance, in French). Good practice, whoever you call: read the devis before you sign it and keep the invoice.
- A lockout and a lock change are separate jobs. If you are offered a new cylinder or lock while you are locked out, ask what it is for, and get a written quote before you agree.
- In 2026, weekends mattered for slammed doors only. They were logged 1.6 times as often per weekend day, while the other job types were not.
The full-year 2026 edition is planned for early 2027 at the same address. When it comes out, the figures on this page will be kept in a dated "previous version" block, so citations to them stay valid.
