Nuki is a smart lock that we sometimes use to work alongside Klevio, offering a complete solution for doors with deadbolt locks. Nuki is a motorised key turner which clamps onto the cylinder on the inside of the door. With the Nuki solution, we will have to change your cylinder which will mean getting a new set of keys. Nuki is a great solution for all the customers who do not want to change their locks but still want to enjoy all the advantages of smart intercom system - Klevio.
