If you want to assign a digital key to your profile, you have to create a digital key first.

Assign a key to your profile so that your profile is automatically selected when you unlock the vehicle or unlock the driver's door using the key. If you use a key that's not assigned to any profile, the guest profile will be automatically selected.
