EXAMPLE: Unlocking a Nuki Smart Lock 3.0 with a Nuki Bridge

To explain the process, we will walk you through the use case of controlling a Nuki Smart Lock 3.0 with a Nuki Bridge via an ekey fingerprint scanner.

1: Installation and activation

Make sure that all the devices are ready for use and connected to your network.

2: Nuki Bridge API

First, activate the Nuki Bridge HTTP API.
Once you have added your Nuki Bridge (and of course the Nuki Smart Lock 3.0), select the Bridge to get to the settings.

Activate the HTTP API.

You will then have access to useful information like IP address, Port and API token.

Get Device ID

Now get the Nuki Device ID and the Device Type. Perform a call using the “GET” method. For example:


Request to Unlock

Request to unlock the Nuki Smart Lock 3.0. For example:


Different Nuki Devices

You can find the different Nuki Device Types here:


The Nuki Smart Lock 3.0 would be “4”.
If you want your Nuki Smart Lock to automatically lock after unlocking, activate the “Auto Lock” function in the Nuki app.

3: ekey bionyx app

  1. Activate the HTTPS requests.
  2. Add the HTTPS request.
    2.1 Make sure you choose the correct method and URL (as described above).


2.2 Authentication is not necessary because the API token is already included in the URL.


As long as the fingerprint scanner can reach the Nuki Bridge in the local network, the HTTPS request it sends will trigger the Nuki Smart Lock. An internet connection is not needed for daily use, but a stable local network is essential.

Important: Please note that, depending on the method, the data may be sent unencrypted in the home network. ekey does not accept any liability for consequences of any kind.
