load an orig.bin,just any into firmware toolbox,can be hitachi or samsung,you get a fw pack with firmware toolbox,its a folder with fw for its name.
now look at the box where the key is usualy displayed,theres a replace key button,just to the left of that is another tiny box with ... on it.click that after loading the orig.bin and it will let you browse to the key.bin,open it and if all is good you will see a key.
if you get one back it up to a cd straight away.
all the best of luck mate,i hope you get the key when you open it.
