Why is Key stuck in ignition on 1990 300zx?

The reason the key is stuck is because the shifter linkage is out of alignment. To remove the key just remove the black plastic piece the surrounds the ignition key , use a finger nail file or something similar , it pops out pretty easy , then you will see a little "Red" colored button , push the button in , you now will be able to push the black button in and the key can now be removed. I know I'm a genius !
