Same here, the key card works by tapping on the door and putting it in on the wireless charger spot. I did have a few times where it didn't work that seamlessly opening the doors, etc. so I just keep it at home. Not confident enough to just bring that and not the keyfob. While it's nice cause it's thin like a credit card, I still want the Phone as Key (Digital Key) functionality. Still no signs of a release yet?I can't use the phone yet, but the key card works by itself without the key fob nearby. I tap the key card on the door, it unlocks the doors. Then if you put the key card against the wireless charger the car recognizes the key and will let you start it.
