To open your vehicle, you first need the key on your phone. To transfer it, an internet connection is necessary. Please find a stable connection outside to ensure a smooth transfer.
Once the key is transferred to your phone, you do not need to connect to the internet to open your vehicle. The connection is exclusively through Bluetooth, meaning you can open and close the vehicle at any time as long as your phone is within range.
This is important to know if your vehicle is in an underground garage where you do not have an internet connection.
However, it is important to note that if the vehicle key is changed or if you lose your phone, you will need to transfer the key to your new phone again. In this case, you will need to find an internet connection again to transfer the new key to your phone.
