Passlock reset instructions are in owners manual.

If your having no start concern's where your security light come's and won't start and then other time's it will start fine then most likely you will have top replace your igniton really common on that model and year car. The best thing to do is take it to a shop and have the body control module code's read and if you have a B2960 and or B3033 then you will need to replace the ignition switch or you will continue to have starting problem's with your car. There pretty easy to change there about 50 for a switch.
