can't get online because it says I'm using my own cd key

It's been an ongoing issue for a week or so now. It's a server issue

I saw this was happening a lot yesterday. People said after some time it will fix itself

yeah
i had that problem
it fixed by itself tryed everything to fix it faster but nothing worked
for me it took around 36 hours

Took me one day to be back to normal.

Check task manager for game.exe, if there, end task, should resolve. If not, you're sol.

wait 24 hours and try again. Create a web ticket with blizzard. Post on the blizzard forums telling them to fix their servers and acknowledge the issue because we paid for a working game.

Or tell them to introduce a low monthly subscription fee of 5$ to pay for a couple of workers working round the clock to maintain the servers, if it is such a huge job for them.
