Canada declares Flipper Zero public enemy No. 1 in car-theft crackdown (arstechnica.com)

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

That isn’t bypassing rolling codes, that’s capturing a single code while preventing it from reaching the car.

And once the code is used once, or the fob gets a new code to the car, the previously captured code is useless.

This isn’t the same thing as bypassing rolling codes.

Hmm, I don't know the precise terminology, I meant bypass as a way to temporarily get around the rolling code system without actually breaking the code itself. You're probably right though
