Agreed, I've followed the advice of the App and Factory Data reset my phone this past weekend, no luck! I've been working with my local service manager, BMW US support and they are now working with technicians in Germany to allow me to reinstall my new 2020 digital key on the same phone as my 2019 key.
Evidently I failed to follow the correct procedure for maintaining control of the 2019 key. When either moving to a new digital key subscription (2019 to 2020) or transferring the phone based digital key between devices or even going through a Factory Data Reset on your same phone, best practice is to:
- First remove the Digital Key from within the ConnectedDrive phone based app (they really ought to make this procedure clear in both the App and iDrive)
- Then remove the keys emergency access from within the iDrive interface from within the car
Otherwise as I have unfortunately found is that removing it from within the car iDrive interface first seems to lock out that phone from being eligible to accept the new 2020 digital key and I get the dreaded
"No Digital Key Usage possible" message within the app.
I've been able to install my new 2020 key on a new phone (not my phone - borrowed one for proof of concept purposes.) I returned the digital key on the borrowed phone hoping that it would trigger a properly returned key sequence; but no luck.
So it seems the BMW Digital key server marks iDrive removed phone keys as ineligible devices for a new key installations, even persisting after Factory Data resets, what a pain!
