I am perplexed. I just bought two NEW keyless remotes for my '03 Silverado from
a dealer using Ebay. The programming instructions were found at
I have followed these instructions to the letter and cannot get these things to
work. I tried reprogramming one of my old ones that stopped working and got it
to work sparingly. It will only unlock the drivers side door and the horn will
not sound when locking is in process. Am I missing something??
