Hi Philip,
Only for clarifying, you have created an application with two keys and 2K3DES cipher. Now you want to change the first key from a 2K3DES key to an AES key?
This is not possible, because you must set the cipher for the entire application at the creation. In an application you cannot use 2K3DES and AES keys! Changing the cipher with the key is possible only for the PICC Master Key.
