Sounds like the ignition switch has gone kaput. The ignition switch come in two pieces, an electrical switch and a mechanical switch.

The switch electrical portion can be replaced separatly from the mechanical portion (tumbler that the key engages). It is not a real difficult repair but requires some mechanical knowlege of how the column is assembled.

This can be verified with electrical test equipment prior to buying a new electrical switch.

A malfunctioning stereo may least allow feature buttons to perform extractions of CDs. Depending on how the stereo was installed, the car would have to be powered on to attain stereo functionalities. Second, CDs have to be inserted with the readable media side facing the appropriate lenses to achieve results. A wrong insertion of the CD into stereo compartment may require forceful extraction. Observe the type of stereo to ascertain CD extraction also known as reset buttons. Usually a tiny area, the reset button allows inserting an object that forces the car stereo to eject stuck disks. Every mean to eject stereo disk have to be performed while the car is turned on to utilize the source of power. An unsuccessful attempt to dislodge CDs in stereo compartments would require auto electrician's consultation. An unsuccessful dislodge attempt usually requires acquiring a new stereo in replacement of the malfunction.

Check your wires they might be touching steel around your car mostly look at your yellow and red wires those are the 1' that give it power and light to your radio also check your radio fuse in the back.

The head unit should have two separate +12V connections: One that goes to a switched 12V power that is switched on/off via the ignition and one that is always energized at +12V. If the head unit's switched +12V lead is not connected, the unit will not turn on (except for when +12V is first applied to the "always on" lead, in which case it will immediately eject the CD). Please respond if this is not the issue. Hope this helps!
