Fudge.
The rear passenger door lock is stuck.  In Ford's infinite wisdom, there is no key lock on the rear doors, only the front .  I had a locksmith come out here and he told me I needed to call a mechanic instead.  I've been PB Blasting the inside of the door around the handle and lock pull knob.
The lock pull knob came off.  There is an 1/8th-inch threaded bolt it attaches to.  I could probably screw on a couple of nuts and try to pull it open.  If I can get the door open, I can remove the door panel.
