Why does my keyless only unlock my driver door? It does also release the hatch, but it will not lock the doors, and when used to unlock, only does the drivers door.

 

It it likely not a problem with the fob or the receiver in the truck if it is able to unlock or lock either of the door. I would guess there is a fault with the wiring to the door lock.

I had the problem of my driver's door lock not being lockable or unlockable by the fob. It turned out to be a broken wire in the door jamb.

 

It will not lock any of them, and only unlocks driver door. I did at one point replace the driver door controls. I believe it listed for a 2000 escalade. I replaced it for window issues.
