Nuki was invented as an easy and, above all, perfect way to replace the physical key with a virtual one – via smartphone. The first Bluetooth Smart Lock in Europe with a permanent internet connection, Nuki opens the entrance door automatically when the authorised person approaches the building, as well as locking it during departure, at the push of a button. Designed as a retrofit solution, Nuki is attached to the existing physical lock while the additional installation of the Nuki Bridge affords the connection to the internet. Thus, the lock can also be managed remotely. The remote function comes in handy for travellers especially.
