I have some questions about using keys.

i have a dm500 with cccam and a amiko alien with oscam.I use a iternal share from the dm 500 to the amiko to view the channels . I like to use some extra keys but i don't know exactly how to use them or put them in the dm 500 or amiko. i'm viewing astra 1,2 &3

I hope someone can point me in the right direction
