Even new garage doors use rolling codes, for exactly this reason. People could break into houses with a flipper and a little patience.
Cloning a fob that has rolling codes, and then using it to unlock the car, may de-auth the real fob and lock the person out of their car until they pay (sometimes $$$) to get it recoded. So, unless you have actual malicious intent it's a pretty shit thing to do.
