What to know about this device

Remote opening and access sharing for an internet-connected lock may use the manufacturer’s account. Use a unique password and two-factor authentication if the service offers it.

The other half of it is more ordinary. Batteries run out, the network drops, and the manufacturer’s service can be down at the moment you are standing at the door.

The lock must work without a network

A network or service outage must not lock you out. Before buying, make sure the door can also be opened with a key, code or another local method.

Check backup access before buying

Choose a lock that still works without the network or the manufacturer’s service. Check the insurance terms before replacing your only lock.

Settings to check

Check these during setup. Later, make sure device updates continue and the settings still match how you use the device.
