If you get the key to turn again, Don't turn it back. There is two ways to remove the ignition cylinder:
1. With the key turned to acc or
2. Drill it out (costs more)

I hope I can explain this without pics......Here goes.

With the key turned to Acc (What ever the first position is) take off the plastic around column. Take a look around the location where the ignition cylinder is set into the steering coloumn, there will be a little hole, in that hole there is a button/detent that you press and the cylinder will slide out. For a temporary fix you can take out all the "h" shaped tumblers (I bet you one of them is slightly bent preventing the rectangle lock to fall within the cylinder....you'll see when you get it apart) Once all the tumblers and springs are out you can put it back together and turn your car on and off as you please.

Note: you will be able to turn the ignition with anything like a key or screwdriver but still require your key with the chip to start it.

Hope this helps
