The symptoms we see most often here
On the solid timber doors of the Ferrandière terraces and the Croix-Luizet houses, winter inland is sharper than people expect. The leaf swells, the keep no longer lines up, and you have to pull the door towards you to lock it. Forcing the key in that position tires the linkage far faster than ordinary wear ever would.
At Charpennes and La Doua the dominant symptom is different: the key spins freely, or no longer slides in cleanly. Years of cheap copies cut for one flatshare after another wear the barrel, until the key blade stops driving the mechanism at all. A key that has been catching for weeks is never a trivial detail.
In the Tonkin residences and the newer Cusset schemes, shrouded multipoint locks combine long linkage with an adjustable roller keep. One misaligned top point is enough to stiffen the whole travel. Adjusting the hinges and the keep often resolves what had been taken for a dead lock body.
What we check before dismantling anything
The diagnosis starts with the door open and the mechanism untouched: clearance of the leaf in its frame, condition of the timber, alignment of the keeps, wear along the key blade. On a 1934 door at Gratte-Ciel, those four points explain the fault more often than the lock itself does. Replacing the case without correcting the rest simply brings the same problem back six months later.
If a key has snapped in the barrel, do not grab the fragment with pliers, because it only pushes deeper. Extraction is done with purpose-made tools and the cylinder sometimes survives. On the street-level doors of the Ferrandière houses, a key rarely snaps on its own: the door had been fighting its keep for weeks. No method and no figure are announced before the door has been seen. The itemised quotation is drawn up on site, before work, and a detailed invoice follows.
A repair to a hall door, a bin store or a cellar access in a Bonnevay co-ownership cannot be ordered by one resident on their own initiative. Those openings are common parts: the instruction has to come from the managing agent, otherwise the job simply does not happen. A neighbour ringing us about the hall door is asked exactly the same question.
