Today when I went to the car the phone unlocked it, but when I tried to put it in gear it wouldn't go. My phone was in my left-hand pocket, so without taking it out, I sort of raised the pocket so it would not be quite so shielded by my body from the sensor to my right. The car then went into gear and drove just fine, but music would not play. Trying to select my USB flash drive, it could not open it, and when I selected a streaming station it would not play. The Voice Command button just said "Try again." And the turn signal blinker blinked but would not make its clicking sound. I got where I was going, and when I came back half an hour later, the phone again opened the car, but the car demanded the key card before it would go into drive mode (this time the phone was in my right-hand pocket). I pulled the card out of my pocket, tapped it, and put it back in my pocket. At this the music started playing and the car drove as normal and the turn signal made its clicking sound as it should. Moral: Even if your phone always works to open the car, always have your key card with you!
