[SOLVED] How to change java card default key with my own keys?

How to change java card default key with my own keys?

I am trying to change a java card default keys (40 41... 4F) to my own key set. I tried to use JCManager but the process of Modify Key returns 6A 88 meaning that reference data not found.

Next I tried GPShell put_sc_key to change but same error returned.

What are proper P1 and P2 bytes for changing default keys?

How can I fix this?

APPENDIX 1:

This is the result of GET DATA command executed in GPShell as below:

APPNDIX 2:

This is the script by which I have tried to change key using GP pro with ACR83 reader:

gp -lock 010B0371D78377B801F2D62AFC671D95
Warning: no keys given, using default test key 404142434445464748494A4B4C4D4E4F

Solution

I found pyResMan useful in my case. It is a python application which helps you easily list your key sets on your cards and add/modify keys.
