Rue du Bac and rue de Sèvres

Changing a lock, from the Bon Marché to the Eiffel Tower
Every corner of the 7th has its own doors: private mansions, apartment buildings, offices. Here is what we do there most often.
Rue de Varenne and Bellechasse
Offices, professional practices and grand reception flats: when an employee or a tenant leaves, a cylinder change is usually enough to regain control of the keys.
- Rue de Varenne
- Rue de Bellechasse
- Rue de Bourgogne
- Rue Vaneau
Around the Champ-de-Mars
Large flats with a service staircase: we change the front door lock and the service door lock together, for an identical level of security.
- Avenue de Suffren
- Avenue Rapp
- Avenue de La Bourdonnais
- Avenue Bosquet
Rue Cler and École-Militaire
Shops and small buildings: locks for shop doors, stockrooms and cellars, with cylinders we can set up to open with the same key if you wish.
- Rue Cler
- Avenue de La Motte-Picquet
- Avenue Duquesne
- Rue de Grenelle
A door slammed shut on rue de Grenelle, a shutter jammed on rue Cler? All our other services in the 7th are brought together on the locksmith Paris 7 page.
The service door, often the weak point
In the buildings of the Champ-de-Mars and the Faubourg Saint-Germain, the service staircase leads straight to the kitchen. Its door, lighter and closed by an old lock, is often neglected, even though it opens into the same flat as the main entrance.
We replace the service door lock with a three-point or five-point model, with a security cylinder. On the inside, a thumb turn lets you get out without a key: the service staircase can serve as an emergency exit, so it is best not to block it off. Other situations are covered on our lock change in Paris page.
What we check on a service door
- The thickness of the door: it determines the type of lock and how it is fixed.
- The condition of the strike plate: a torn-out strike plate is as good as no lock at all.
- The cylinder: should it take the same key as the front door, or a separate one?

Service door locks: your questions
A photo of the service door, from the kitchen side and the staircase side, helps us give you an accurate price.
Does the service door need just as strong a lock?
Yes: a burglar looks for the easiest way in, and the service staircase is used far less than the main staircase. A multipoint lock with a security cylinder brings both doors up to the same level.
Can a service door that is no longer used be blocked off?
It is better to keep it usable: the service staircase can serve as an emergency exit. A security lock with an inside thumb turn protects the door without preventing you from getting out.
Can the same key open the front door and the service door?
Yes, if both locks take cylinders of the same model: we order them so that they open with a single key. It is more practical day to day, and you only have one set of keys to keep an eye on.
How much does a new service door lock cost?
A single-point lock costs €210 incl. VAT; a three-point or five-point lock, from the prices in the table above. The exact price depends on the door: you are given it before the work starts.
