Ahh....sorry, thought you just wanted receiver code. This is usually used for resetting box (i.e. Manufacturers default settings etc)
For keys for watching channels, you'll have to have a look around. Spend a few hours searching as they're definitely about. You don't say what else you're using with receiver (cam etc) Is your receiver patched? If not, it may be worth getting it done as it *should* au on vi*ccess & ired*to
It's against board rules to post keys here, so please don't ask. Just try a google for your receiver make and all should become clear. ;)
