I bought two from Ebay, less than 20 bucks. Make sure You get the ones that have the Cargo release button. Think it was around 35 bucks too have a Locksmith program them both and they work perfectly. Good luck
I walked into the nearest chevy dealer told the parts guy what I wanted. He pulled one off the shelf handed it to me after I paid him $60.00, Then he told me to pull up to the service bay where a guy walked out and programed it. I was gone in a total of 15 minutes, $60.00 poorer but with a new remote in hand. It was well worth it to me.
