store key A and key B with Access bits in Sector Trailer Block

hello ,
I have a mifare card and I can write and read in this card with defauts keys() , but I want to store keys A and B with the Access bits in the sector trailer bits , and I am enable to find the way that let me to do this .
Can anybody help me , I am blocked since 1 month and I have to find a solution for my project .
Please help me.


This is my code
