    It could happen in your Prius, or it could happen to your friend's 4Runner.

    If both of you own a Toyota with wireless keys, and get in each other's car, in can cause the vehicle not to start. I hopped in my friend's 2010 4Runner, and he couldn't start the car up. He arm/disarmed to no avail. Even tapping the key to the start button didn't work (maybe didn't hold it there long enough). Then I saw the dash blink with that key icon, and thought maybe my key was the problem, so I jumped out of the car. Car started right up after that. So, there. :D

    The more you know...

    My father and I both owned a 2010 Prius and a 2012 Prius. I got in his and he got in my car with each others keys in our pockets and we never experienced this. Not saying it can't happen because I just don't know if it can or cannot but in Prius I can say it has never happened to me nor him over the course of 4 years.

    Haven't noticed such an issue when I've test driven Gen 3 Priuses (including PiP), the Prius v and Rav4 EV w/my Gen 2 smart key in my pocket.

    I think we did have a report of it happening in another two-Prius family. It is likely going to highly variable, depending on how close each fob is to the car's internal antenna(s), how strong a signal each transmits, and could easily vary significantly with the specific radio designs of different car models and mixtures of fobs.

    Wow, that would be a bit interesting. I guess that is when the key has to go into the trunk or something so it doesn't get detected...surprising that Toyota didn't think about that.

    If the last 5 bytes of the binary ID happen to be the same.... Actually I haven't a clue, just a wild guess.
