The uses that earn it a place here
The real benefit is not doing away with keys, it is opening and closing a right of access remotely. Around chemin du Grand Revoyet, where many households live on shifted hours, it saves leaving a key under a plant pot for a relative calling in during a night shift. The same applies to a cleaner who comes while you are at work.
For a home let to a short-stay occupant near the metro terminus in the south of the commune, a code is created for the length of the stay and then deleted. The timestamped log shows who came in and when. Guests are given the code by message rather than meeting somebody for a handover on the doorstep.
In Le Bourg the commonest use is domestic. An older resident receiving home help, a child coming back alone from school, a tradesman expected during working hours: each access is granted for a window and revoked afterwards, so nobody has another key cut from the family ring.
What the door imposes on the model
The door dictates the choice, not the other way round. On a multipoint lock in a Beauversant house, the question is whether the mechanism works by turning the cylinder alone or whether the handle has to be lifted: in the second case a motor fitted to the existing cylinder will never engage the top and bottom bolts.
Old doors in the centre raise a question of leaf thickness and cylinder length. A leaf outside standard sizes, a rim lock, timber that has moved: compatibility is measured on site, and on an old leaf the thickness can vary by a centimetre between top and bottom. Reversibility matters too for a tenant, who has to hand the door back as it was.
Two points are regularly overlooked. Cold and damp on the floor of Le Vallon shorten battery life, and a lock that has stopped warning you is a lock that will fail at the wrong moment. Radio signal, second, travels poorly through the thick stone walls of the old houses: the bridge has to be placed accordingly, and a mechanical override key remains essential.
