Grant an access, then take it back
On a house at Manissieux a day passes through several hands: a home help, a tradesman expected during office hours, a neighbour collecting the post. A code is created and revoked in seconds, whereas a key lent and then forgotten means changing the cylinder. That cylinder stays in place, and the key still works from outside.
For a flat let at Bel Air the appeal is the same seen from the landlord's side: inventories, keys handed over on a Sunday evening, a contractor between two tenancies. Access opens and closes remotely, and the key ring stops travelling from one tenant to the next. Keep the original cylinder for making good at the end of the lease.
In a unit on the Berliet estate it is the timestamped log that counts: knowing who opened the service door, and when, beats a spare key handed to a contractor. Deliveries and outside work are handled with temporary access rather than extra keys, and an access can be closed the evening someone finishes.
What to check before buying
Battery life first. Cells run down, and faster on an exposed door: a pedestrian gate or an unheated garage at Manissieux will not match a sheltered flat door. Check exactly what the fallback is, a mechanical barrel or an emergency power point, before choosing a model. Serious models start warning weeks in advance.
Connectivity next. Bluetooth means being close by; remote control means a gateway and a network that works. A router going down must never stop you getting into your own home. In a house spread over one floor, common in the eastern plots, put the gateway near the door concerned rather than two rooms away, or the link drops. The local fallback is the point to settle first.
Strength last, and it does not change. A motor added to a tired lock in a block at Les Alpes does nothing for resistance to a break-in: convenience and mechanical security are separate subjects. A door that closes badly is adjusted before electronics go anywhere near it, otherwise the motor strains on every turn.
