The question is, does the remote fob connect to a cellular or some other network that requires a subscription? A lot of vehicles come with apps where you can check tire pressure, flash the headlights, remote start from way beyond the distance of a normal remote. This requires cellular connectivity. So starting the car from your phone app requires connecting to manufacturer servers which then ping the car from a cell tower. Not sure if the fob does this, that would be impressive. If its just 433mhz local radio then shame on Toyota.
