Question type: Maintenance & Repair

I had new battery installed and when I try to start car the diagnostic center says may not start due to security code--how do I reset the security system code(s)?

Without the security code you will need to take this to the dealership along with proof of ownership (a title or registration card with your name on it) and have them reset it for you.
