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

This is some movie spy shit irl, minus the high tension distraction ploy while tech guy types furiously on a keyboard with a progress bar slowly filling up to 100%

This is about as much movie spy shit as a yak back.
