“Further, a large number of different pseudo random algorithms are used, so that if by chance one fob syncs with the wrong vehicle one time it won’t do it a second time. “
Just got back from a business trip in Tampa. At the hotel, after checking out at 5am, we used the key fob to unlock the rental car. Our car, AND the car next to us bot unlocked, and they were different models.
We did it 5 times in a row because it freaked us out. It was still dark, and the tail lights of the car next to us came on, which surprised us. We did it again, thinking someone else was doing it or someone was in that car. Nope. Just us.
We knew it should be impossible, but there you go.
totally weird, but theoretically possible if extremely improbably.
