How do you clear anti theft light on a Bonneville 2000?

To clear the anti-theft light on a 2000 Bonneville, first ensure that you have the correct key for the vehicle. Insert the key into the ignition and turn it to the "On" position without starting the engine, and leave it there for about 10 minutes. This should reset the anti-theft system. If the light remains on, you may need to check the key or consult the vehicle's manual for further troubleshooting.
