2002 Silverado Z71 keyless entry

I know its probably already on here somewhere but I cant find it. Does anyone know the process for programming keyless entry remotes on a 2002 Silverado Z71? My truck came with only one and I bought 2 more on eBay that have the same part numbers. Thanks in advance for any help. Mike

Transmitter Programming Procedure (Method 1 - No Tools Required)
Close all the vehicle doors.
Insert the ignition key into the ignition lock cylinder.
Press and hold the door unlock switch.
While holding the door lock switch in the unlock position, cycle the ignition ON, OFF, ON, OFF.
Release the door unlock switch. The doors will lock and unlock to confirm the program mode.
Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of approximately 15 seconds, the doors will lock and unlock to confirm the programming of that transmitter.
Repeat the previous step to program up to four transmitters.
Turn the ignition switch to the RUN position in order to exit the keyless entry transmitter mode.
Operate the transmitter functions in order to verify correct system operation.

Thanks Cobra, Worked just like you said, I really appreciate the help.
