Reprogramming remotes

[mountainbiker]

There are HUMMER H3 remotes on eBay for sale, but they seem to say take the remote to the dealer to reprogram with a scan tool.

These eBayers, however, (1, 2) are saying they supply a programming instruction sheet. And, here is a $6.95 service that might have instructions.

Are there magical steps that can be taken with the originally supplied keys and remotes that don't require you to visit the dealer / scan tool? The Elcova Forums H2 FAQ have these instructions. Who wants to go test 'em out on the H3?

Maybe f5fstop can find us a H3 service bulletin for reprogramming.
