Hey nimaltd!
I am not sure if I understood you correctly. If you are trying to authenticate with different keys, it might not work - because there's only one key that is valid for authentication => If I understood you right, if that's what you are confused about. Perhaps that 1 Byte change that you are mentioning provides the correct key to Authenticate with your DESFire and others ofc don't.
BR,
David
