You would all lough to your grave if you would see how shit is the immo system in these cars are. To add a new key to a car you have to read immo data of the car and than decode it to get a password to make the key. In these cars you just sit in the car, make the car go into add key mode and than just touch the key to antena, and thats it, no passwords no immo data reading.
Since 2019 you have to pay 800$ a year to have your bmw use adaptive drive, 150$ to use the app.
