Bluetooth
If Bluetooth still does not work, unpair from your vehicle
AND smartphone. Then try re-pairing both again.
For BLE phone key issues, when in the vehicle, navigate
to Controls > Locks and remove your phone as "Phone
as Key". Then set it back up again. But only do this while
you are in the vehicle and have a reliable back up key
available (such as a key card).
