Surface-mounted locks on century-old doors, add-on deadbolts, worn cylinders: in the old buildings of the islands and the Marais, we change locks without spoiling the character of the doors. We work everywhere in the 4th, at night as well as on Sundays; you know the price before we arrive.
In the 4th, a lock fitted onto the door, rather than set into it, is still common. Here are the areas where we come across it most.
17th-century front doors, often thick but irregular: the surface-mounted lock has been changed several times, and each generation has left its holes. We choose a model that covers the old marks.
Old buildings around the courtyards of the Village Saint-Paul: deadbolts and surface-mounted three-point locks, which we replace like for like or with a multipoint lock.
Small old flats, often rented: changing the cylinder of the surface-mounted lock each time a tenant leaves costs little and stops spare keys from circulating.
Rue Chanoinesse, rue des Ursins: some of the oldest houses in Paris, with low doors and crooked frames. Adjusting the door matters as much as the lock itself.
A door opening, a door reinforcement or a metal shutter in the 4th? It’s all on the locksmith Paris 4 page.
A surface-mounted lock is screwed onto the inside face of the door, with a strike plate fixed to the frame. On an old door, replacing it means respecting the thickness of the wood and the position of the old fixings.
Three situations come up again and again: the lock works but the keys are lost, and a new cylinder is enough; the lock is worn, and a model of the same size replaces it; the door deserves better, and a surface-mounted three-point lock strengthens the locking at the top and bottom. To go further, an A2P-certified multipoint lock or a full door reinforcement are still possible.

A photo of the lock, from the inside, and of its key is often enough for us to give you a price.
Not necessarily: a three-point surface-mounted lock, firmly fixed to a sound door, holds out better than a single-point mortice lock. What counts is the number of locking points, the quality of the cylinder and the strength of the strike plate.
Yes: the surface-mounted lock is fitted on the inside, and only the cylinder shows on the landing side, with a rose or plate that we choose to be discreet. The old keyholes can stay in place as decoration.
A Picard Kléops starts at the price shown in the table; allow €210 incl. VAT for a single-point lock. The exact price depends on the thickness of the door and the condition of the frame: you’ll know it before we start.
Often, a new cylinder or a clean is all it takes. If the lock’s mechanism is worn, we replace it with a model of the same size. Avoid cooking oil in the cylinder: it clogs up the mechanism.
