Please help CD player problem

I put a cd in my 6 disc cd player, for the first time since I bought, and it wont play. You can hear it clicking and it says cd initialization. It won't play, eject, or let me load another cd. Every time I turn the car on or off the cd player keep making noise I just want to get the cd out, I m afraid it will run down the batterie. I called gm they were useless. Does any one how to eject the cd. Is there anything I can do please help.
