    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

      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
