About this app

With the Clex Key App, the electronic locking units of Uhlmann & Zacher can be opened and closed using the smartphone. In the process, the smartphone communicates with the locking units via Bluetooth® Low Energy.

High security standards

To ensure the necessary security, you will receive an invitation to set up your Clex Key app from the operator of the locking system by e-mail and also a short message on your phone. Only after confirming both parts of the invitation, your key can be used to open the locking units using your smartphone

Functions:

- Receive mobile keys and unlock doors via Bluetooth®
- Execute block requests for the administrator
