OK then that is very reassuring that its a little more difficult that what I have seen on YouTube. Apparently there has been a number of thefts in Toronto area with some GM and Toyota vehicles so W-five did a segment on the news regarding this.
Maybe since the i3 is so rare, its not a highly desirable vehicle.
I'm not suggesting it's not real. There's a spoof attack that records the code when you press the FOB button, jams the signal, then allows the thief to use the stored good code at a later time. This works on garage door openers, also. But there's also a relay attack that works on proximity, and re-transmits your FOBs code over long distances to a person standing near the vehicle. The equipment used to do this is supposed to be dead cheap.
I know BMW has begun addressing this using key fobs that don't pulse out a signal if they're sitting still on a counter, and there was talk of making the systems sensitive to signal timing, in effect nulling an unlock command if there was a few milliseconds delay in receiving a code. Whether the i3 specifically employs either of these defenses, I don't know.
But I also estimate I'm 100x more likely to suffer a smashed window. And even though I was half tongue in cheek, I'm confident my i3 isn't a desirable stolen car target.
