Where can I find XUX #2 remote?

I just bought a 2004 Envoy XUV. The dealership only had the driver #1 remote. They agreed to buy a #2 remote for me, but we are having trouble locating one. The only remotes I have been able to find are #1. Any help would be greatly appreciated. And yes, I checked Ebay.

I found a couple online that say they are #2 for XUV, but they do not have the button for the rear window. Does the #2 have this button?
