How to use

Register the smart lock key within the Netatmo access control app or the system administrator interface following the manufacturer’s enrollment procedure so it is recognized by your smart lock.

Manage permissions and revoke or reassign the key through the access management software as needed. Keep the key clean and store it in a dry place when not in use to maintain reliable operation.

Avoid exposing the key to extreme temperatures or prolonged moisture to preserve its functionality.
