keys won't come out of ignition

Sad to say nothing, you need to get a boost or recharge the battery

Ditto

I'm not sure if the above answers are correct. You can view a YouTube video on how to remove the key. Apparently there is a little screw/holecover under the steering column on the left hand side. Remove that cover and put your finger inside. There is a little button. Press that button in, and turn the key towards you and remove it.
