Ah, so the cars still have shitty security implementations, only now it’s in the direction of “car needs service if someone tries to playback a previous signal”.

Though how does it work when you hit the button while out of range of the car?

It should be each fob has a private key that is used to generate a cryptographic hash of a random challenge string. Or hell, even give a rolling code a sequence number so they the car and fob can resync if necessary (I don’t think this would break the security, since the sequence could be started at a number other than 0).
