How do I know if the batteries of my Smart Lock are empty?

Nuki will inform you in several ways if the batteries of your Smart Lock are running low

As soon as the battery status of your Nuki Smart Lock drops below 20%, you will receive a warning. This way there is enough time for you to replace the batteries before they are depleted.

Nuki App

You receive a battery warning via the Nuki app. You can find the warning in the notification center by tapping on the bell symbol at the top right.

A blinking Smart Lock

The battery level is not only shown in the Nuki app but also directly on the Smart Lock by a LED signalization on the rotating ring.
Learn more about the LED signalization.

Push notifications

You can additionally receive push notifications informing you when the battery level drops below 20%. In the Nuki app, you will find the option "Manage notifications" in the "Feature & Configuration" section. Here, you can log in with your Nuki Web account. This is essential, as notifications will then be transmitted through your Nuki Web account.
You can activate Nuki Web in just a few steps.

Email notifications

To receive email notifications log into your Nuki Web account and activate "Battery alerts via Email" in the administration of your Smart Lock. You will be notified by email when it is time to change your batteries.
