I've thought of it considering living in New England. Did some research and found a car starter that uses the factory key but considering the Supra(BMW) complicated system I don't want to mess up the car. Toyota could've easily installed one considering the MSRP; I mean my 2018 Civic had one...
The issue I'm having is connecting to screen mirroring. I'm not sure if it's my phone but I cant find my car within screen mirroring besides my neighbors Apple TV.
I activated the Video in motion, Video Via USB and followed the apps procedures but can't seem to get it to work. My phone wont let me connect to screen mirroring either so let me know if you're able to get it to work.
I don't think every car is effected but it's safer to do it than be sorry. I got mine done today for the heck of it. Took no longer than 45 min at least for me.
