Default Security light on dash will not turn off

I recently programmed a replacement key for my 2003 C5 Corvette and now whenever I start the car, the "Security" light comes on the dash and remains on the entire time I am driving. Is there a way to reset this?

How about providing background information leading to this?

Might try a power reset, disconnect negative battery cable for 5 minutes or so and touch the positive battery cable before reconnecting the negative cable.

Do you have DTC B2721 set?
Pages 13-14 have troubleshooting information related to the security light illuminating.

Thanks for your reply and input. I tried disconnecting the battery as you described, but unfortunately, that did not clear the security light. The good news is that it did clear a different annoying message that I was getting, so was still beneficial. Thanks again for your assistance!

Thank you for responding and providing the anti-theft systems pdf. I will give it a read and see if I can figure out what is going on with my security light. Best regards.
