Hi my name is Kristine, I have a 98 Catera. I believe i need a new ignition cylinder, my key doesn't turn (at all!!!)once in the ignition. Inserting and removing the key is not a problem. Pls let me know if it could be something else as well. If i were to replace the cylinder w/ a used cylinder (w/ key included.) Will the key need to be re-coded or does something need to be done w/ the security system. Also does anyone have any help diagrams or instructions on how this is done. I have never removed/installed a cylinder on a Cadillac. Thank you soooo much for anyone who can help~!~!~!~
