Yes. All that. If my wife takes my key and not hers, the seat moves to where she left it until I have locked it again....I think. I haven't figured out what the order is. They can tell all sorts of stuff from you key....last oil change, etc. etc. It probably reset the features.

What I hate is when I give it to the dealer valet, they always turn off my automatic headlights and mess with the radio HVAC.
