From the box, it was the smart lock we wanted for our inside garage door going into the house. We wanted the convenience of not having to use a key and also needed it for neighbors who have security system access. Installation instructions appear to be a no-brainer task, too.

This smart key would be an asset to one's home using typical household routers so buy with confidence otherwise.
