Operate devices compatible with BlueSecur using the Hörmann BlueSecur app. You can send permissions (keys) to family or friends, for example, via text message, e-mail or messenger. You don’t even have to be home to send a key, since keys are transmitted via a certified server in Germany. Manage your keys right in the app. The BlueSecur app must be installed on your mobile phone ahead of time. If a user hasn’t installed the app, they will be forwarded to the app store.
