Damn wtf. I think I learned of this and forgot

It’s near impossible to clone the signal from newer rolling codes, you need to trigger the key fob with out the signal reaching the car and then recorded with the flipper zero, then played back to the car. It takes a lot of coordination using the key fob. Here are some videos of it.

Those videos aren't for cars with keyless entry. Those cars have a bladed key for placing in an ignition lock cylinder to start the vehicle (or in the case of the mini, which is a car I actually own, into the little slot for the round key fob).The flipper zero recording a code isn't what I am talking about when I talk about repeater attacks. What I'm talking about is using a receiver to receive and amplify the code so that they can use keyless entry (where you simply touch the vehicles door handle with your hand with the key within three feet of the car) and only requires you to have the key on you. Did you read the other comment I linked? This isn't about having a key with buttons that are required to be pressed to enter the car. This is literally about passive keyless entry. Please go read the articles I linked.

I mentioned nothing about signal cloning and you clearly didn't read.

Oh my bad, I was inferring that from the original article. Those articles you posted are good and talk about the CAN attack, but the original article talks about the rolling codes using a flipper zero like device.

My bad, I didn't intend to come off badly, I just literally had a similar conversation when someone who didn't read what I wrote, completely ignored whole sections of the article, and I may have come off a bit terse as a result. But you are correct about the flipper zero specifically.
