There are a number of reasons why your door might not lock. You could have something stuck in the door for example.
Stuck how? Lock? Door?
"My lock is stuck"?
spray with WD40 if that doesn't help replace the door lock
You can not close any door if the locking mechanism is stuck in the locked position. You must first get the mechanics to unlock.
door car zipper key/lock window
door lock actuator stuck,bad door latch if rear door has child saftey on a bad door entry handle.
The expedition door lock relay could be stuck causing the grinding noise. Check to insure that the lock relay is working properly.
If the problem is from a faulty electric lock, then repeated operation of the ignition switch and door lock switch (i.e. a few dozen times) may get the lock to function. Worth a try - boring but easy to do.
I would call a locksmith to get it manually unlocked, and then after that you can either get them to fix it or remove the door panel and fix it yourself. It's probably fairly simple, such as a broken lock rod retainer (they're all plastic). Sounds like the power door lock plunger has gone out, or is jammed up. Check fuses, and if they are fine you may need to replace or unstick/lube the lock plunger.
