Updating smartphones' app versions
A corresponding message appears on smartphones if a new AirKey app update is availa-
ble. Depending on the Google Play store settings, the AirKey app is automatically updat-
ed or updated only after having manually confirmed the update.
You can continue to use the AirKey app as usual once you have completed the app ver-
sion update.
You require a Google Play store account to download apps from the Google
Play store.
It may be the case that AirKey app updates are recommended, but not
mandatory. In such cases, a corresponding message appears in the AirKey
app. This will restrict certain functions. However, you will continue to be
able to unlock locking components.
EVVA recommends to always keep the AirKey app version for smartphones
up to date and to activate automatic app updates in the Google Play store.

The locking component itself outputs a special "Battery empty" warning upon identifica-
tion at the locking component. Please refer to
Locking component signals
for more infor-
mation about signals.
Proceed as follows to replace the locking component batteries:
