So does Acura/Honda. Used to be on the key fob, but now it’s through a phone app with a subscription. I thought it was ridiculous until I learned how it worked. Instead of being RF based, it works using Sirius XM satellite data pushes.

I’m not sure how to feel about it now. I think the satellite version is more secure, but does have a different cost structure.

(I only found this out when our account wouldn’t work for months. Then a few months ago there was a security issue with that system that reset our account.)

Secure, eh?

Tl;dr: They didn't actually bother to put security into the app
