2004 Silverado door lock transmitter

[Disney Dude]

I have to replace one of my door lock transmitters, and have checked this forum for the correct procedure to reprogram the transmitter. I have found several variations of the reprogramming, but none specific to the 2004 Silverado.

Does anyone know the correct procedure for reprogramming the 2004 Silverado transmitter? I still have one that works, but want two.

Thanks in advance.

if you can look back for a post I made a while back, it know for sure it works. I've done it on several vehicles using the same procedure that I posted.
