What would prevent the Key Fob from working?

Bought a used 2005 G6 for cheap, needs some body work and a few other things like the door latch fixed, dome light, etc but it came with a key fob that doesn't work. I replaced the battery but still not working. Provided that it is coded to the car (I wonder because the key only fits in the ignition and not the door or trunk) is there anything that can prevent the fob from working? Drivers power door lock switch works, passengers doesn't. Curious what I can check before taking it to the dealer to program it and want to prevent a situation where it fails and I still have to pay for the time spent.

I had disassembled André rested with foil to bridge the button contacts and still nothin’.
I can’t seem to edit... autocorrect. I disassembled the key fob and tested using foil instead of the pads to bridge to connection and still nothing.
Yeah I saw that in the menu and it is on but the fob doesn't work with new battery. Again, this might not be coded to the car and the previous owner never got it to work and assumed dead battery. Can the fob be coded with a consumer-grade scan tool or does it need to be done with a special scan tool at the dealer? Ugh and now the key is stuck in the ignition, which I guess is due to the cable that runs from the shifter to the ignition?
I found this but it didn't work:

some web site said:
- Get in your Pontiac G6 and make sure all the doors and the trunk are closed.

- Put your key in the ignition and hold the "Lock" button on the driver's car door.

- Turn the G6 key in your ignition from "On" to "Off" while holding the "Lock" button, and do two more cycles of "On" and "Off" in quick succession.

- Release the "Lock" switch on your door and press and hold the "Lock" button on your keyless remote for 10 to 15 seconds.

- Remove the key from the ignition of your G6, and test the programming.
