Here are two other ways to do it.

Before starting, ensure the ignition is in the off position and all vehicle
doors are closed. You must complete Steps 1–5 within 30 seconds or the
procedure will have to be repeated. If the procedure needs to be
repeated, wait a minimum of 30 seconds before beginning again.
1. Place the key in the ignition and
turn the ignition to the on position.
2. Press the power door unlock
control three times.
3. Turn the ignition from the on
position to the off position.
4. Press the power door unlock
control three times.
5. Turn the ignition back to the on position. The horn will chirp one time
to confirm programming mode has been entered and is active.

press the unlock control. The horn will chirp once if autounlock was
deactivated or twice (one short and one long chirp) if autounlock was

I know this is an old thread, but no luck. Method one works, but doesn't. Going through setup i only have auto lock, not auto unlock. So doing this method only disabled auto lock, I know as I went through setup afterwords and found auto lock now set to off instead of hoping to find auto unlock feature added to setup.
Method 2 did not do as described. Once I hit the 3•4 button, it unlocked all doors, and while holding and pressing 7•8 it just popped the back glass.
I understand it was a safety issue to not have auto unlock, but that was literally a bogus excuse. My 06 impala had the auto unlock feature with the option of being off, driver only, or all doors.

The person responsible is an almost 30 special needs BIG boy. I'm not concerned with a child jumping out, there isn't any in home (or ever in vehicle)
I'm beginning to wonder if getting front door lock systems and installing them in the rear would work, so they would unlock when handle is pulled.
