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.

If the security light is flashing you may need to do a relearn procedure. Turn ON the ignition, with the engine OFF. Attempt to start the engine, then release the key to ON (vehicle will not start). Observe the SECURITY telltale, after approximately 10 minutes the telltale will turn OFF. Turn OFF the ignition, and wait 5 seconds.
