how to unlock sky?

You may note like this answer but its the way that it is.

Hacking Sky was done very successfully in the 1990s. So successfully in fact that current Sky boxes and Conditional Access cards are now locked tighter than a drum.

Sky actually own the Conditional Access Intelectual Property via a subsidiary and that company does not leak.

If you are looking at free channels forget hacking Sky.
