Make sure that the car is in park and the finger tab on the gear shift is good. if not try to lube the key with wd-40 then try again, if it still doesn't work and the key is not bad you probably have a bad ignition key body.
the ignition switch is bad
Either something is wrong with the key or there is something wrong with the switch. You can try to spray some WD-40 or something like it into the switch and wiggle the key to see if you can get it turning. Otherwise you may have to replace the ignition switch.
Trouble code P0320 means: Ignition/Distributor Engine Speed Input Circuit
The problem could be the lock for the steering wheel. Move the steering either side while trying to turn the key.
When you first turn on the ignition the indicator lights should briefly illuminate to demonstrate that they are working. If the light stays on after the test cycle, it is an indication that something is wrong.
use small Allen key in access hole while turning and pulling clockwise
What is wrong when your toenail starts turning green?
No. The coil has to do with spark to ignite fuel inside your engine. There is probably something wrong with your ignition system or your starter.
It probably is not the key. It could be the battery or starter. Try lubricating it with powered graphite. If that does not work then the ignition tumbler assembly may need replacing. They do wear out over time. Of course you may be using the wrong key.
Does the steering wheel have turning pressure on it, try turning wheel to pull pressure off the ign. ?
May need a new pi tail behind the ignition switch.
