I believe I saw in the settings section (Doors and Windows?) where you can specify how the car locks/unlocks itself. I recall changing mine to know when I walk away from my car to automatically lock, and it does the same as I approach (unlocks).
I do not have a cool Digital Key though, so I'm not sure if that is different or not...but I am curious as to where you get the Digi Key. Mine is a US Spec but living in Italy, so unfortunately, I'm unable to connect it to a US system for unlocking CarPlay and other things.
