In your older post on this you mentioned that the driver's door key barrel just spins.
See this picture. In the lower right corner you see the two levers.
Now I will confess that I'm not 100% sure about what I'm saying here. It's a few years since I had my locks out and memory isn't what it used to be.
The small lever, the one with the little round hole, is what, IIRC, the key barrel connects to via a rod.
I don't know what would happen if your spinning barrel caused the rod to disconnect from that lever and/or jam that lever into it's locked position.
As I said, I'm not sure. But you have the door cards off so it won't cost you anything to stick your fingers back there and twiddle that lever.
