How it works

NUKI turns the key on the inside of your door whenever you want. Turn it manually, activate by touch, with the Nuki Fob or operate your lock with the Nuki smartphone app.

When the Nuki Bridge is installed additionally, Nuki connects with the Internet. Thus, the Smart Lock offers full remote control of the door lock via the Nuki app on your smartphone from anywhere and anytime.

Configuration and installation

The Smart Lock is mounted on the inside of your existing Euro Profile cylinder. 

The Smart Lock is glued to your door with special adhesive pads. We recommend using Nuki Smart Lock only with cylinders which have an emergency function. This function ensures that the cylinder can be used with a key on one side, when another key is inserted on the other side. Different suppliers of cylinders name this function differently, so e.g. it’s called “emergency function” or “external key override function”. Note that your key should rotate at the inside when you lock from the outside.

You can remotely control your locks using Nuki Bridge. Make sure it is installed in ≤5m distance to the Smart Lock.

NUKI app

NUKI app is free of charge and can be downloaded  on iOS or Android smartphones. You can control all smart locks in one place and share up to 100 mobile access permissions per Smart Lock.

Available functions in the app:

  • Lock/Unlock

Easy installation on the existing door lock

The Nuki Smart Lock is mounted on top of the existing door cylinder on the inside of your door. To fix Nuki to your existing door lock, one of two alternative mounting plates is either clamped onto the lock cylinder, or glued to the surface around it.  The key will be operated by Nuki as soon as you have configured your Smart Lock with the Nuki app.
