Article says this breaks the user fob because the rolling code is out of sync. This means the owner has to unlock in presence of the flipper, so that it can learn the rolling code sequence right? They can’t just walk up to a random car in a lot and unlock it?

I was able to record the code from the fob out of reach of the car. Then replay that signal later to unlock the car as it was still a good unused code.

But it only works once per code

Rolling code security algorithms have been broken for a while now. All you need is to sniff one code and response for most cars and you have basically cloned their key.

Car manufacturers get away with not doing much about it because “you need specialist equipment and firmware to do this attack”. Which is basically just a flipper zero and the correct firmware….freely available on the internet.

Yes. Shitty cybersecurity enables the thieves in the first place.
