2000 Chevy Tahoe Limited Keyless Entry

IF HAVE HAD MY 2000 CHEVY TAHOE LIMITED FOR ABOUT A MONTH AND A HALF NOW AND JUST NOTICED WHEN I PRESS LOCK ON MY KEYLESS ENTRY REMOTE IT ONLY LOCK MY 4 SIDE DOORS AND LEAVES MY BACK TAILGATE DOORS UNLOCKED! IF I PRESS THE REAR 2X BUTTON ON MY REMOTE IT UNLOCKS THE REAR BACK DOORS, IF THEY WERE LOCKED WITH THE KEY. I WAS WONDERING IF I REPROGRAMMED THE REMOTE WILL IT LOCK ALL DOORS?

TIREBURNER I HOPE YOU CAN HELP ON THIS ONE

THANKS BEFOREHAND

BY THE WAY IT THE OLD BODY STYLE

The Lock button should lock all exterior doors.
If not then there is a problem with a component, and reprogramming the transmitter will probably not help.

Here is an Exerpt from repair manual,

The procedure is all jumbled up because the copy and paste does not keep everything in order.. sorry
