Thank you. It did not unlock body parts I can't move. However, it does work very well for other parts. I suspect people will find your script useful, so you didn't waste your time.

And I think I figured it out. When I click on Edit Dependencies for the body parts I can't move, there's this extra line:

It says Left Hand::EMPTY-INVThreeFinger

It's the same for the other parts I can't move: neck, the fingers of the other hand, etc.

When I delete that line, the body part works normally.

I have no idea how that got in there. I don't even know what Edit Dependencies means, and would never try to mess with it.
