Kia offers that feature but if Toyota offers it they have kept it hidden, I just bought a 22 Highlander they made slight mention of the continuing charge for key fob function. First year is free, there after will be continuing price increase I am sure.
New Toyota cars have the ability to start the car remotely via an phone app. That means that the car has to connect into the internet some way in order to connect to your phone. There is a emergency button that allows you to talk to someone in an emergency. I presume that that bit of electronics connects into the phone network or some other network and ultimately the Internet.
If you can start a car, you (or someone) can probably shut it down too.
