I thought this could not happen. Oct 2016 MS. As I do EVERY morning, I put the dog in the back seat, then my briefcase containing my key fob on the front passenger seat. Close the doors and walk around to the driver's door, press the handle - nothing. Trunk release button won't open it, nor any other handle. This may not be a problem in other locations since usually I could just open the car with the app on the phone. In my garage, however, the car itself does not get a signal because, I suspect, the roof is lined with a foil backing. It gets worse. My spare fob is in another briefcase in the trunk - where from a prior incident I know is a dead spot. Tesla service tries to open it remotely, but (foil lined roof again) they cannot connect to the car. Eventually, someone was sent to physically break into the car, which they were able to do rather easily. So, how does this happen? Especially when the fob was in the exact location where it had been literally hundreds, if not thousands of times? I am far too aware of the dead spot in the rear, but the fob on the front seat?
