Hi , thanks to every one for helping here.

Finally y remove the whole piece to work more confortable .
I made the "perfect tool" , I feel how I push on the spring, but I cannot remove the tumbler or nothing .
Today I going to work with some cutting machine or something , to many days with no car .
My key is stuck on the tumbler, and I cannot remove it, I started the car one time, and now cannot start it again, until i remove the key and insert it again, may be the problem is the tumbler is in some "magic" lock something extra but the spring???

will see after today, with the heavy tools.

regards
EZe
