Hi,

Working with ZedBull: If you would like to add new keys (lets say eg 4 keys) to the Fiat Van using Megamos crypto ID48 chips, is there going to be 4 keyfiles (imagefiles) as well OR JUST ONE (combined) file ?

So if you have original dump file of the Eeprom (in this case it is 93LC56B, 256 bytes) and 4 blank chips, you can precode these chips with ZedBull and after reprogramming Eeprom you can have 4 new working keys?

A) It is a matter of adding new keys so I guess ZedBull will make 4 key different files? If so, after precoding you will have original dump and four (4) key files as well?

B) OR: is it possible that ZedBull can make only one working Eeprom file (which will be 256 bytes as well?) including all necessary key data?

If the case is option A, how can you make the reprogramming of the Eeprom in the right way so the van will start by using any of these new keys?
If you program 4 files one by one to the Eeprom the result (the Eeprom final content)
will be the last one? Right?
