FWIW I've used mine to duplicate both of our car key fobs (middle 2000's Mazda and middle-2010's Jeep) so it'll probably be very dependent on make/model/age as to whether it uses rolling codes.
I'm not convinced that there is a 'non destructive' method to find that out though.
There’s a pairing mode you put the car in and it accepts the new keyfob and probably records it’s seed / counter / etc at that point.
