I don't get this. Why would you think you would have any problems? Every car ALWAYS comes with a method to get in that does not require any cellular or internet connection. The S and X come with regular key fobs. The 3 and Y come with that RFID card that can be held up against a sensor on the door pillar.
The way I understood it, the MX key fob functions via cellular transfer of unlocking code. does it work if put near the door sensor without cellular? I suppose I’ll find out when I take my new MX onto the wildlife refuge and lock it with Sentry mode. Let’s hope it is not a hard lesson Because there isn’t any Tesla road ranger or cellular connection. Only a very very long walk to get to where I could get a tow for a very very long way.
Correct. The key fob uses pseudo bluetooth to communicate with the car directly (no cell or Internet required). But key fobs do fail sometimes. That is one of the reasons you get two of them.
No, no, not at all. That would require an extra cell plan, with a SIM card for LTE, etc. etc. It's nothing like that. It's just the same old standard super-simple wireless transmitting to the car that key fobs have been doing for 20+ years. It just sits in your pocket, and when you get close to the door, it's in range, and it unlocks.
Yes, it's directly talking to the car--no cellular at all.
Right, the key fobs are direct to the car and more reliable. My wife doesn't carry a purse, so she wants to just use that remote driving from her phone, which does rely on a few communication steps, because it's cellular (times 2) and needs AT&T's network to be functioning, and needs Tesla's servers to be functioning. So when she does this a lot, there is sometimes about once every year or two that there is some communication problem somewhere, and it doesn't work. So then she has to call me to come bring a key fob. But it's rare enough and we're local around town enough that it's not too much of a bother.
