The cylinder alone settles most cases here
The cylinder holds the secret: it comes out once a single screw on the faceplate is removed, and it is replaced without touching anything else. A season of lettings at Villeneuve-Plage, keys handed to a cleaning firm, a village house bought without knowing how many copies are in circulation — in every one of those cases, changing the cylinder alone is enough.
The mechanism is replaced when the mechanism is genuinely at fault. A multipoint lock with a point that no longer engages, a bent faceplate, a bolt that stays out on a house door down on the Loup plain: a new cylinder would change nothing there. The diagnosis on site settles it, after working the door open and then shut.
One trap is common on this stretch of coast: the size of the cylinder. Too long and it stands proud of the escutcheon, giving something to grip; too short and the key cannot work properly. The backset and the thickness of the leaf are measured before anything is ordered, especially on the walkway doors at the Marina, many of which still carry their original ironmongery. That measurement is taken at the door, never from a photograph or a reference copied off an old invoice.
Building rules, master keys and doors seen from the lane
At Marina Baie des Anges a key rarely opens the flat door alone: the hall, the bike store, the way through to the port or the underground car park often sit on the same bunch. Replacing a cylinder without telling the building manager breaks that master-key scheme. We check what the key commands first, then replace while preserving the rest.
Up in the village the constraint is as much visual as mechanical. The solid timber doors in the lanes climbing towards the keep are visible from public space, in an area where external appearance is regulated. We adapt the visible ironmongery and the finish rather than impose a modern set that would jar on an old leaf.
As a tenant at Les Plans or Vaugrenier you may replace a faulty lock, but tell the landlord in writing and keep the parts removed: they will be needed to put things back at the end of the tenancy. A detailed quote comes before the work, and the itemised invoice handed over at the end is your proof of the replacement.
