Hi Ingo,
If you get an authentication error, the key you used is not the PICC Master Key. This is what you do: select application 0 and using key number 0 means the PICC Master Key.
Please have a look to the end of this post:

Changing the PICC Master Key requires a successful authentication to the default key, in the case of a blank card, and a successful change of the default key afterwards.
