I had the weirdest experience with the car tonight. I've never had the mobile key work more than 10% of the time, so I just carry the fob around. But I left tonight to pick up dinner with just my phone and license/credit card in my pocket. When I walked into the garage, the car turned on and I left without thinking about it. When I got to the restaurant, about 8 miles away and parked, I realized I didn't have the fob. I'm so used to having it on me that for a minute I was totally confused about how I had been able to drive it there. And then I was worried that once it turned off, it wouldn't turn on again when I came back to it and I'd have to call home for someone to come with the key fob. But the mobile key worked perfectly. As I walked up to the car, it unlocked. I realize this is totally normal for those of you who use the mobile key all the time. But in the nine months I've had the car, this is a new experience for me. I did open the app five minutes before leaving and put in a location in the navigation to send to the car. I don't know if that's what made it work.
