More info on SECA 2 :
When the card is activated by the supplier the following keys are created: MK01, OPK 0C,
OPK 0D and OPK 0E, (MK00 is not created or changed) (where MK stands for
Master/Management Key and OPK stands for Operating Key). In some cards (usually those
which are pre-activated) MK02 and MK03 are also present, but they are of no interest to us.
Generically when a card leaves the manufacturers it has the following MKs defined: MK00,
MK 02, MK03. Commonly the activation sent from the supplier erases the MK02 and
MK03 before building the MK01 and OPKeys, this is the old system they used in SECA1
when the MK02 and MK03 of each card were always the same! MK02 and MK03 could be
used as a "backdoor" to open the cards. SECA2 activations have no reason to erase MK02
and MK03 because they differ from card to card.
