The lock box pairs with your phone, and doesn’t need WiFi to work. It doesn’t even need any installation—it can be secured to most door knobs or railings. Through its companion app, you create a PIN code to send to folks like a house guest, babysitter, or dog walker to unlock the box and get to the keys or key cards stored inside. You can share and delete PIN codes, and synchronize with an Airbnb rental calendar to create time sensitive PIN codes for guests, too.
The lock box can also be opened by Bluetooth using a phone nearby. It’s a safety measure that’s been smartened up, and it makes managing access to your home easy, wherever you are.
