Keys changing hands with the Sud-Gironde seasons
As the service hub of the Sud-Gironde, Langon houses a great many people who only stay a while: a post at the hospital or the clinic, a year at the lycée, a seasonal contract in the vineyards of the Graves or the Sauternais. Homes change occupants more often than elsewhere, and at each changeover the real question is not mechanical: it is about the keying. How many copies have been cut, and where are they now? Replacing the cylinder alone answers exactly that, without touching the mechanism or the door.
Another very common situation here: a house taken back after an inheritance or a long tenancy, in the town itself or in a neighbouring commune. Nobody knows any more how many keys were cut or who they were entrusted to — the neighbour who watered the plants, a tradesman, a former tenant. The inventory then matters as much as the lock: main entrance, side door, utility room, garage, gate, and sometimes an outbuilding whose key disappeared long ago. We change the cylinders on the ways in from outside and keep the mechanisms that are still sound.
Cours des Fossés, rue Saint-Gervais: dimensions measured door by door
In the centre, one door often serves two purposes. The shop occupies the ground floor, the home occupies the floor above, and the stairs are reached through a street door that belongs properly to neither. Before changing anything, you therefore have to untangle what each key actually opens: shop, stockroom, back courtyard, staircase, landing. A replacement decided without that groundwork almost always ends up depriving someone of an access they had been using without ever having mentioned it to anyone.
Then come the dimensions. On doors like these, nothing can be ordered over the phone: the backset, the centre distance, the thickness of the door leaf and the state of the timber around the strike plate all have to be measured on site, one door at a time, because two neighbouring buildings on the rue Saint-Gervais may not share a single dimension. Fitting a high-performance cylinder into a tired door frame achieves nothing serious: better to rework the strike plate and its bearing in the same visit. We show you what we find before anything is taken apart.
