I am Nuki – your door, just smarter.

Nuki uses state-of-the-art encryption mechanisms commonly used in online-banking. All communication with the Smart Lock is protected with end-to-end encryption. We also have our Smart Lock regularly inspected and certified by independent security institutes. The Nuki Smart Lock was once again certified by AV-TEST as a secure smart home product in 2025.

All Nuki Smart Locks are installed on the inside of your door without needing any technical know-how, drilling, or special tools. Our Smart Locks can be installed and removed without leaving any residue or marks, and are therefore also ideal for rented apartments.

While all Nuki Smart Locks can be installed in minutes on your own, the exact installation process would depend on the type of Smart Lock you own.
We have step-by-step guides on our website and app for a quick and simple installation experience.

You can find out whether your door is compatible with the Nuki Smart Lock here.

You’ll always receive a warning when your lock’s battery level drops below 20%, giving you more than enough time to quickly recharge your device.

Users who own a Smart Lock Ultra, or any other Smart Lock combined with a Nuki Universal Cylinder, can still use a physical key to open their door - even with the Smart mounted on the door!
For all other users, if your current door cylinder has a so-called "emergency function", you can also simply use your keys to unlock your door.

Even if you don't have your phone with you, you can still open your door in many ways:

• Asking someone with an access permission to open it for your remotely
• Using a smartwach
• Using one of our accessories to open your door with a code, fingerprint, or a Fob
• Using the Nuki Web
• We recommend that you only use Nuki with a cylinder with emergency function. This means you can always unlock your door with your mechanical key, even if there is a key inserted on the inside of your cylinder, which is the case when using the Nuki Smart Lock.
• For Smart Lock Ultra and users who own a Universal Cylinder: You can always use your physical keys to unlock your door, even with the Smart Lock installed!
