Your 1991 300zx has no power to the entire car and the key is stuck in the ignition?

If your 300zx has no power to the entire car and the key is stuck in the ignition you have to press the emergency button located in the ignition. Simply remove the black piece from your ignition.(its a black cap)..and when removed you will see a small red button..if you see that push that and press the "push" black button, turn your key and pop it out.
