Most smart locks only utilize Bluetooth Technology, limiting your access within a certain perimeter. However, Kevo is upping the smart lock game with the Plus. It's a Bluetooth Gateway which can be connected to your home's internet router to grant you access to your Kwikset Kevo from anywhere via Wi-Fi. That means you can let in your contractor while you're at work. That means letting your mother in when she comes for a visit, and it means letting your husband in when he forgets his own key and phones inside.
