I was just wondering if anyone has experimented with programming RFID keycards as a keyfob replacement.
I'm sharing a Tesla with a couple of people and while the mobile app works great for unlocking etc ... I would love to figure out a way to use keycards just to unlock the doors.
So I guess my question is twofold:
- Is there a built RFID reader on the Tesla Model S
- Does anyone have any insights on how to come up with the right datastring to put on an RFID card that would send the correct OPEN command to the car ?
