I just noticed today that I have a red button on the top of my fob. I didn't before. Either Elon is able to do updates to the fob remotely or the tooth fairy came in and changed my fob. I just just checked my wife's fob and there is no red button. I had my car serviced a few weeks ago - maybe they changed it then, but I didn't see it until now. They did deliver my car back in the evening and it was dark, so I may have missed it.
