Aren’t all cars within the past decades using rolling keys?
This article does not do a good job of explaining what the attack vectors are.

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.

These are different attack vectors.
The classic one was listening to a key, then impersonating it later.
Rolling keys fixed that.
For keyless, the usual attack is working as a relay.
Victim is 30m from their car, too far for keyless.
Attacker stands between the car and the victim with a transceiver that links the car and the key together, despite the distance, and opens it.
