Access the MIFARE keys update menu
(MorphoAccess
TM
220)
Each data sector on a MIFARE card is protected in reading and
writing by 2 keys of 6 bytes each. These keys are noted A and B.
Since the card is composed of 16 sectors, there are actually 32
keys.
When you present a MIFARE card to the MorphoAccess for an
authentication, data can be read only if the keys which protect it
are the same as the keys initialized into the reader. By default both
keys A and B are set to 0xFFFFFF for the 16 sectors in the
MIFARE module of the MorphoAccess. These default values are
called
Transport keys .
You can change the value of the keys thanks to the hotkey
CL KEYS in the Administrator menu
(16)
. You will need for that an
administrator card containing the new keys to initialize. Please
check the Enrollment Station documentation to know how to create
an administrator card.
While you are in the administrator menu, press the key CL KEYS .
The MIFARE KEYS UPDATE screen appears.
Present the administrator card to start the update.

If you perform this operation, the old user cards won't be readable anymore, since the keys won't be com-
pliant anymore.
