Hopefully it won't come to this but you could take apart your CD player.
If there isn't a spring release hole in the front of the console, then only taking the whole thing apart will get the cd out. Outside of removing the unit---I've heard that disconnecting the car battery for a short time, then reconnecting it causes the unit to reset itself, enabling ejection.
Get the car company, or keep fidgeting with it untill it comes out. Like, try various ways to get it out.
B-F-H-!!! as a last resort you could try a pair of tweezers with something like duct tape on the ends for padding to keep them from scratching the disk. or if you could get the sticky side of the duct tape to stick to the CD, that might help.
what you need to do is take the CD out of the stereo if this does not work take the CD out of the stereo and try one more time
