Mfkey32v2 calculates Mifare Classic Sector keys from encrypted nonces collected by emulating the initial card and recording the interaction between the emulated card and the respective reader.
While performing authentication, the reader will send "nonces" to the card which can be decrypted into keys.
Mfkey32v2 is not magic it cannot create you a working credential without an initial card. The Keys generated are not keys to open the door, they are keys to unlock and read sectors from inside the card itself.
