Glad you saw sence. It’s hard to know what in Tesla is Musk and what is Tesla. Considering that half the staff at Tesla have to Elon proof the factory so he doesn’t stop production because he doesn’t like the colour of the robots or something. The cybertruck is all musk.
Depends on how they have set it up but in the ideal it will have be individually linked to a user. Iv heard of cheep complex managers just setting each fob to the same internal id. Meaning you can’t deactivate a fob or track the users. If anything it would be the same as CCTV on the lobby and public spaces of a complex. I would doubt that you would need it to exit as most doors need to let you out without resistance. This is possibly a fight between security and privacy. The other residence in the complex are more concerned with unwanted entries.
I’m guessing there is a recalibration mode but I’m sure the modern car market would demand you go to the dealership to run that program.
