You're right - you can open everything from the iPhone Tesla app. I always have my phone when I drive, so maybe the fob is unnecessary. At least I won't accidentally open the FWDs, as happened way too often with my SigMX. And I've saved $150+. Thanks for the advice. I have too much stuff anyway.I've got to go to the service center next week to wrap up some delivery issues and they have them in stock there for $10 cheaper than the website so I'm just going to get it there.
That said, after getting my phone setup with Apple Shortcuts to do quick things like unlock, or unlock and open the doors, I may be less interested in the fob as that's pretty much just as fast...it's free, and I can do it from my watch or phone without opening any apps or carrying anything else around with me.
