Locksmith in Boulogne-Billancourt
Boulogne-Billancourt is the largest commune in Île-de-France after Paris, and its buildings tell two stories: Art Deco blocks and architect-designed villas around Parchamp and Albert-Kahn, new residential development at Le Trapèze and Île Seguin. In practice you cross one avenue and go from an old flat door needing refurbishment to a residence under access control.

What the local building stock actually changes
Boulogne reads in two layers. Around Parchamp, Albert-Kahn and the town hall, Art Deco and architect-designed villas dominate, with original doors the buildings want to keep visually intact. Reinforcement therefore goes on the inside face.
On Le Trapèze and the riverside everything is recent: badge access, multi-point flat doors, and often a master-key plan run by the residence. Replacing a cylinder without checking that can cut off your access to the common parts.

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.

What we do in the area
Frequently asked questions
How do I know if my cylinder is part of a master-key plan?
If the same key opens your door and the lobby or bike store, it's a master-key plan. The cylinder then has to be ordered through whoever manages the residence. We identify that before starting rather than fitting an incompatible model.
How long from Paris to Boulogne?
Boulogne borders the 16th, so it's one of our fastest areas. The exact time depends on the hour and which bridge we take, and is given on the phone with the price.
In a recent Trapèze block, can I change my cylinder freely?
Yes for your own flat door, which is private property. Be careful, though, if the cylinder belongs to a master-key plan run by the residence — common in new developments: replacing it on its own can cut off your access to the common parts. The tradesperson checks this first.
How long does it take you to reach Boulogne from Paris?
Boulogne borders the 16th and is one of our fastest areas. The exact time depends on the hour and which bridge we take; you get it on the phone with the price, never a guess.
