CD is stuck and eject button doesn't work

No it doesn't. The head unit is faulty and requires repair/replacement.

Check to see if something is jammed in it

This can be a problem. First try rebooting the machine, and holding the eject button when you hear the startup tone. Hopefully, that will force-eject it.
If that doesn't work, you'll need to get creative. Get a playing card or something similar, and put some rolled-over tape on one side close to the edge, so there's a sticky side out. Turn the computer off, and try to get the playing card into the CD drive, with the tape making contact with the stuck CD. Reboot, holding the eject button when you hear the eject button again, and pulling the card out. Hopefully, the CD will come out with the card. If it doesn't work, just keep trying, and you'll get it out eventually.
Generally what causes this is keeping CDs in the computer for an extended period of time, especially while the computer is powered off. Make sure you remove all CDs before moving or turning off your computer.

If the Cd drive is not ejecting, try going into My Computer, and right clicking the Drive and selecting "Eject". If that doesn't work, then take a paper clip (or any other piece of wire that small, which does not have a sharp end) and examine your CD/DVD drive. There should be a little paperclip sized hole, this is usually next to the Eject button. Slowly push the paperclip into the hole, until you feel that you have pressed something, and then remove it. The drive should eject. This should work regardless of whether the computer is on or off.

It's time to take the computer to a professional computer technician, for trouble-shooting, and probable replacement, of the disk-drive.

If pressing the eject button does not eject the tray, look for the small pin hole on the cd drive and insert a paper clip to press that hole. It would manually eject your CD tray. Hope this helps.

press & hold the eject button

All You Have To Do Is Unscrew The Radio And Take It Apart. Take The CD Out And Put It Back Together Again. This Solution Worked Like a Charm For My Stereo.

Well, Recently the same thing happened to me, My bro dropped my WII on the floor and the eject button on it got stuck i was soo mad!!!
I tried loads of ways nothing really hard, just follow this and hope fully the WII will eject:

1.Make sure the WII is stood up properly.
2.Then switch on the WII (As i said early the WII won't eject the CD.
3.Now look near the eject button if it is stuck follow (A) or if not coming out follow (B).
(A1).Right if it is stuck and not coming out then the top bendy bit of the eject button put your nail through it and press it down it should eject but after a while it did not work any more for me :(.
(A2).Now, Disconnect all the Cable's in the WII not TV leave it for a while (and don't smash it again!), After a while approx 5 Min's plug 'em back in, switch on the WII then press eject hopefully that will work :D.
(B1).Now if it does not come out either look inside the drive or WII (I don't suggest that) or just do what i did with A2 hopefully that will work.

Hope your WII works by now and enjoy ejecting cd's from your WII but 1 more thing before you go (DON'T BREAK YOUR WII AGAIN OR YOU WILL HAVE TO DO THIS ALL OVER AGAIN :P AND IT MIGHT NOT EVEN WORK IF SMASH IT TO MANY TIMES!!! SO BE-CAREFUL!!!!
