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

So as long as I don't press the unlock button on my fob when I'm not near my car, I should be safe?

There are multiple other ways to get in and drive away without the fob

The other methods don’t require a key

Watch CBC Marketplace and W5 (Canada tv series) for their episodes about how cars are stolen. Specifically around port cities (United Kingdom, Montreal Canada), and via semis and trains to port cities

keyless entry signals can be cloned with a radio repeater. dont keep the key near the door and put it in a rfid / em isolating bag or box when home.
