Are Prius key codes unique?

    Can somebody with another Prius unlock another Prius using the smart key system? I went to the store last Saturday night and when I went back out to the parking lot, there was some lady inside my car trying to start it. I asked, "Excuse me, what are you doing in my car?" Sure enough, there was another black Prius a couple rows away and she had mistaken mine for hers.

    More likely, I left the door unlocked, but all the same - is it possible for the keycodes to be the same?

    Sounds like you missed an ideal opportunity to find the answer. To bad you didn't lock your car and walk away bit then let her try to unlock it; then tried the same thing on her car with your smart key.

    Is she wasn't able to start it, then no it can't. Part of the SKS system is starting the vehicle as well.

    I doubt they are unique, but there are certainly more different codes than a mechanical key would allow. I remember when I had a 64 Chevy getting into my car and starting it, then realizing it was the wrong car because this one had an automatic and mine had a stick. Evidently Chevy was notorious for having a small number of key settings.

    Techman is correct....if she couldn't start it, the codes do not match.

    ;) Now, I suppose out of 100,000+ Pri on the highway, there COULD be matching codes. But it's like a needle in a haystack. I certainly wouldn't worry about it. The odds of two alike parked near each other, same color, at the same time is like winning the mega-lottery.

    I agree but the OP didn't say if she could start it or not or even if she had, only that she was "trying to". I would hope each car has a unique code but that would depend on how many bits are available to identify an individual vehicle, and we have no idea how many that is. I would think it provides many more possible combinations than a mechanical key would in any case.

    it's rolling code, not fixed code. so the chances of that happening are infinitesimally small.
