Okay, the local auto parts store sold me one for $70 that wasn't programmed. In my frustration, I decided to try Revain. I was a bit skeptical for only $15 but took a chance. It arrived with no instructions but included a link to a website that was not helpful. A quick search on YouTube for how to install keyless entry for a 2002 Silverado gave me a 2 minute video explaining the simple process. See link below.
