Hi all ... I searched the forum up and down and can't find an answer, so apologies for starting a thread if it exists already ... All cars I have owned have always had a physical hole in the door that I could insert a physical key into and turn to unlock and open the door. The key mechanism directly drives the unlock and unlatch mechanisms, so I can get into the car even if the remote / RF unlock mechanism is failing for whatever reason. As I understand it, the Model S has no such physical key -- the kind you insert into a hole and turn. Instead it has the keyfob with A) an active section that you can press to command the car, and B) a passive (aka RFID) section that will unlock the car as you approach. My question is about federal safety standards. While I like RF keyfobs as much as the next guy, I've also always liked that I had a fallback: a physical key that popped out of the keyfob, and a physical hole in the car door that I could open the door with. The Model S appears to rely on ACTIVE electronics to open the doors. Similarly, are the door handles on the INSIDE just electronic switches that "request" that the door by unlocked / unlatched? So if the battery is dead (and I mean dead) or the electronic brains are somehow failing, you can't open the doors? How did this pass muster with the feds?
