Hi Daniel,
In SL1 (MIFARE Classic emulation mode) you can only use the keys A and B in the sector trailers. The AES sector keys (in 0x4000, …) can be used only in SL3. In SL3 you must be authenticated with key 0x4000 to read and write sector 0 for example. You can change key 0x4000 if you want after authentication.
For the switch to SL3 you must prepare the “switch keys” in 0x9000, …
