Which one to choose
Smart Lock Go if you mainly want to open the door with your phone when you’re at it. It runs on AA batteries and is the cheapest way in. If you later want to lock and unlock from anywhere, add Remote Access for €49 once – there’s no monthly fee.
Smart Lock Pro for most homes: Wi-Fi is built in, so remote access and smart home control work out of the box, and the battery recharges instead of being replaced. It keeps your current cylinder.
Smart Lock Ultra if you want the smallest and fastest Nuki or would replace your cylinder anyway – it comes with Nuki’s high-security Universal Cylinder.
Accessories
All three work with the Nuki Keypad, the Fob and the Door Sensor, which tells the app whether the door is open or closed. Nuki also sells them in sets with a lock, so check the bundles in the shop before buying them one by one.
