I'm worried about watching something I don't subscribe to and it coming out on my bill what is the orange key ??? Does that mean I don't subscribe and it off limits to watch
Yes, the orange key means it is off limits to you. There is no danger of you being charged for it because you will not be able to access a channel you do not subscribe to.
If you click on a locked channel you will be told it is not part of your subscriptions, In order to watch you need a subscription to it.
