What it changes, and what it leaves alone
The real gain is not doing without a key, it is opening and closing a right of access remotely. In the houses of Le Village where an older person lives, the home help or the nurse gets in without a spare circulating around the neighbourhood, and the day the carer changes you revoke the code. A key handed to someone is never quite taken back.
On the plateau the limit is sharp. The halls at Les Semailles and Les Alagniers were refitted with collective access control whose badges belong to the landlord or the agent. A smart lock on your landing door does not open that hall: your visitor still needs the badge, the entryphone, or somebody to come down.
The access log has real value for an owner letting a house at Crépieux-la-Pape from a distance. They know who came in and when, they cut an access off in seconds between two tenants, and they avoid the cylinder change that an unreturned set of keys would otherwise force on them.
The practical constraints in Rillieux
Battery life is judged on site. A house door exposed to the plateau wind, at Vancia or out by the woods, sees sharp swings in temperature, and cells run down faster there than on a landing door sheltered in a heated stairwell. Mechanical operation with a key has to stay possible whatever happens to the electronics.
The radio link is the other thing to check. The pisé and cobble walls of old Rillieux, like the concrete walls of the plateau blocks, happily swallow Bluetooth and Wi-Fi. Where the bridge and the router sit then matters as much as the model, and a garden-level flat may have no usable coverage anywhere near its door.
In rented homes, reversibility usually decides it. A motor unit fitted inside over the existing cylinder comes off without a trace and leaves the key working from outside, which suits the social housing of the plateau — with the landlord's agreement first. The original lock is kept so it can go back at the end. The survey is made on site and the itemised quote comes before fitting.
