This is a most excellent place for technology news and articles.
You can still mount it to another machine if you have the key. It's an extra layer of pain in the ass, though.
I don't use an M$ account so if your key is backed up to the cloud (aside: can't wait to read the headline about when that gets breached) I don't personally know offhand how difficult it is to extricate your BitLocker keys from Microsoft.
