I see five buttons on that fob. How many do you see? You identified three functions. Also, which button locks the transmission and why would anyone ever do that, from a fob no less?
Yeah that’s what it looks like to me, although I’m not sure that remote start is a thing on EVs (never owned one). I hit remote start every time I get in my vehicle. Gets the AC/heat going and lets the engine idle down a bit.
