Locksmith Paris 3rd arrondissement
The 3rd covers the upper Marais, from the National Archives to the Carreau du Temple: 17th-century mansion houses, cobbled courtyards and original carriage doors, in buildings where the co-ownership rules govern how a flat door may look from the landing. Galleries and showrooms sit alongside the housing, adding shopfronts and shutters to secure.

What the local building stock actually changes
In the upper Marais many addresses are mansion houses divided into flats: a carriage door on the street, a cobbled courtyard, then a narrow staircase. Two locks often need work instead of one, and the carriage door belongs to the common parts.
Building rules here are strict about how flat doors look, especially on original landings. We check that before quoting, because reinforcement refused after fitting is a cost to everyone.

How a call-out works
- 1
You call or message
Describe the door and the situation. On the phone, or in writing on WhatsApp, you get the price of the job and a realistic arrival time for your street — not an unverifiable promise.
- 2
The tradesperson comes and assesses
On site they check the lock type and the state of the door, confirm the least destructive method available, and have the amount agreed before touching anything.
- 3
Work, invoice and guarantee
The job is done, tested in front of you, and billed at the agreed amount. The invoice itemises hardware and labour — the document your insurer or landlord will ask for.
What doesn't change, whatever the area
On site in under 30 minutes, depending on the area
Someone sets off the moment you call — day or night, weekends and public holidays included.
The amount is settled on the phone
You know what you'll pay before anyone travels, and that is the figure you settle once the job is done.
A qualified, insured tradesperson
You speak to the person handling your job, from the first call through to the invoice.
Everything is in writing before we start
A detailed quote before work, whatever the amount, under the French regulations of 24/01/2017.
Guarantee on our installations

What we do in the area
Frequently asked questions
The carriage door is broken — who decides on the work?
It's a common part: the decision belongs to the managing agent or a general meeting. We can secure the entrance urgently and provide a quote written to be put to the agent, which avoids leaving the building open while a meeting is arranged.
Can you work if the courtyard has no vehicle access?
Yes, and that's true of much of the 3rd. Equipment is carried in from the street, which changes neither the price nor the time we quote you.
Can a door be reinforced in an old Marais building?
Usually yes, but how the door looks from the landing is governed by the co-ownership rules, and sometimes by heritage protection on the façade. The reinforcement then goes on the inside face with a discreet certified lock. The tradesperson checks this before proposing anything.
Do you cover the courtyards and passages of the 3rd?
Yes. Many upper-Marais addresses open onto a courtyard no vehicle can reach: the equipment is carried in by hand, which changes neither the quoted time nor the price.
