New installation - How do i unlock channels?

[lewis94]

I installed a Micromax 550D box using the instructions on this forum and now have scanned the following satellites and got around 400 channels however I dont know how to unlock them. I can operate the menu to find Nagravsion, Viaccess, SECA, Viaccess2, BISS, Nagravision2 and TPS. The satelites I scanned on were Astra, Hotbird and Sirius. Can anyone offer a starting point how to enter the keys I need

Thanks

Ive now updated the software etc on the box and loaded all the channels on Astra and Hotbird however I still cannot figure out how to unlock the channels. I have manually inputted the keys from another part of the forum but nothing is happening. Am I doing something wrong??
