Read everyone, this is hype, and Canada is being dumb on this one.

The Flipper Zero is also incapable of defeating keyless systems that rely on rolling codes, a protection that's been in place since the 1990s that essentially transmits a different electronic key signal each time a key is pressed to lock or unlock a door.

Most of this reaction is due to staged videos on TikTok and politicians not understanding technology. Maybe they'll stop a few joyriding kids, but car thiefs aren't using F0s.

With a jammer it's definitely possible to bypass rolling codes with Flipper, but it's only temporary and has limited usefulness

It's pretty difficult, you need to get the rolling code from the fob, but you also need to jam it so it doesn't reach the car.

Then you have one opportunity to replay the code before the holder of the fob hits the button in range and rolls the code over.

So even if you manage to set that up that only gets you in the car, it doesn't get it started.

Yes correct, just pointing out that it is technically possible to get around the system
