^^^^^^^^^^^^ NONE OF THAT!
like said above. if the key wont turn, chances are the steering wheel is locked and will need turned, then twist the key.
The key will need power to get back into the off position. there should be a key release area under the steering column by the key. it is a little round(plastic cover) that can be taken out with a flathead screw driver. once it is out of the way, stick the screw driver up the hole... you will feel it hit a button. then simply turn the key off and the khey will come out.
hope all will be well once the battery is charged!
