CD Eject Key Not Working (Help!)

I am very new to Mac so if this is easy to fix sorry.
My G4 only had one CD ROM drive so I added a second to the bay. However once starting up the system the eject key did not work. I took out the added drive and set things back to how it was. Now the key still does not work. How can I get the key to work. I can't even get a CD in the drive with out it. I have also tried to reboot holding the mouse button down with no luck!
thanks

Nevermind, I found that the ribbon got a tore and that was the problem. I replaced it, using one off my old PC and it works now.
