2003 Buick Century Question: Security light on

You need to have the computer coded out. A plain code reader will not recover antitheft codes. Look on craigslist in automotive services to see if someone will come out to scan the car with a scanner that can scan security codes. Once you have the codes post them on RepairPal for us to help you.
