keyless entry programming

I just read the description for programming keyless entry on a 96 suburban and wanted to know if the procedure is the same for a 2000 LT or is it different.

Start with the ignition OFF, hold down the power unlock button on the door panel. Turn ignition key ON, OFF, ON, OFF. Release power unlock button on the door panel. The locks will cycle once.
Hold down the keyless entry transmitter LOCK and UNLOCK buttons for 15 seconds. The locks will again cycle once.
Repeat step #2 for each additional keyless entry transmitter.
Turn the ignition on to exit the keyless entry transmitter programming mode. Programming is now complete

Will this work on a 1999 Suburban also?

I read the programming for a suburban 1999 keyless entry. I could not get the programming to work on my 1998 suburban, is the procedure the same

When reprogramming the remote control door lock reciever, All transmitters must be programmed at this time in order for the transmitters to operate the vehicle. Transmitters not programed at this time will not work and the procedure will have to be redone with all the transmitters.

Ground pin 4 to pin 8 of the data link connector (DLC). The receiver will respond by locking and unlocking the doors, and activating the liftgate window release (if equipped) within 2 seconds.
Press and hold the LOCK and UNLOCK buttons simultaneously on the first transmitter to be programmed until the locks cycle (approximately 10 seconds).
Repeat step 2 for up to four total transmitters to be programmed (if available). The receiver will respond by locking and unlocking the doors and activating the liftgate window release (if equipped) within 2 seconds.
Remove the ground applied to the DLC.
Lock and unlock the doors in order to verify the transmitter operation.
Activate the rear window release in order to verify the transmitter operation.
