Update: Finally I see BMW listed in my Samsung Wallet. Last night I was able to setup my Digital Key on my Fold4. Yayyy, now I dont have to carry that bulky key anymore.
Old: Same issue for me too. Atleast a couple months ago, BMW app didn't allow me to setup the digital key. But I believe from last month bmw app enabled this option for z fold4, but unfortunately I can't add the key to samsung digital wallet. Come on Samsung, we pay $2k for your high end phone, but you haven't rolled out this feature yet. (While the older models like s22 ultra or note 20 ultra are supporting this feature)
I just purchased a new BMW and was bummed that I couldn't get the digital key to work on my Samsung Fold 4. I finally got it to work by completely updating my phone (allowing all the system updates that I ignored). I also made sure Samsung wallet was updated. Once it was all updated I could finally see BMW as an option to add as a digital key but when I selected it I still got the "device is not supported" error. I gave up for the night but then something obviously updated over night as the next step... to go to your car with all keys... finally popped up and I was able to fully add the key.
I thought this would be the last issue I had but then when I actually tried to use the digital key to unlock the door it wouldn'twork... with either the key card or with my phone... I then tried both to start the car and they did work! Finally, after using both to start the car I tried both again to unlock and lock the doors and had success! Lots of drama but it FINALLY works! I hope this is helpful to someone else.
