Well since the key won't turn at all, you will probably need a new cylinder. They come out with a good key by turning it to on, then use a tool from the bottom to push the release button. If it can't be turned it may need the steering wheel removed and drilling it out.
LOCK CYLINDER Removal & Installation (Functional) Disconnect negative battery cable. Turn ignition switch to RUN position. Insert a 1/8" drill bit or wire through access hole in trim steering column trim (below lock cylinder). Press retaining pin inward and pull out lock cylinder. To install, lubricate lock cylinder. Turn lock cylinder to RUN position. Press retaining pin inward and insert lock cylinder into housing. To install remaining components, reverse removal procedure. Removal (Non-Functional) 1. Disconnect negative battery cable. Disable air bag system. See appropriate AIR BAG RESTRAINT SYSTEMS - EXPEDITION & NAVIGATOR article. Remove steering wheel. Twist cap until it separates from ignition switch lock cylinder. 2. Using a 3/8" drill bit, drill down middle of ignition lock key slot about 3/4-1" (19-25 mm) until ignition switch lock cylinder breaks loose from breakaway base of ignition switch lock cylinder. Remove ignition switch lock cylinder and shavings from lock cylinder housing. 3. Remove bearing retainer, bearing and gear. Thoroughly clean all metal shavings and other foreign material from housing. Carefully inspect housing for damage. If damage is apparent, replace housing. Installation 1. Install gear, bearing, and retainer. Lubricate cylinder cavity. Turn lock cylinder to RUN position. Press retaining pin inward and insert new lock cylinder into lock cylinder housing. 2. Before rotating ignition switch to OFF position, ensure cylinder is fully seated and aligned. Use key to rotate cylinder to ensure mechanical operation is okay in all positions. NOTE: Use this procedure to remove ignition lock cylinder if key is missing or cylinder is frozen.
The added problem is if you dont have the lock cylinder set up for your key, the new key needs to be programmed into your vehicle or it won't start.
If you have them set up the tumblers for your key it's ok and use your old key, and reprogram the new key like this.
PROCEDURE #6 2 keys required. Cycle key 1 to RUN, then OFF. Cycle key 2 to RUN, then OFF. Cycle new key to RUN.

If the old keys can be used, yes, if new keys are needed, Ford will charge 1 hour, usually 90.00 dollars to progrma the keys to you car.

The added problem is if you dont have the lock cylinder set up for your key, the new key needs to be programmed into your vehicle or it won't start. You did remover the top piece? The lock cap? It should come out if drilled far enough, we are just drilling past the piece that locks it in place. Try just a wee bit deeper. Dont go any deeper than the length of your key though.

Yes the ignition tumbler is bad and needs replacement. Here are some diagrams to help you get the problem fixed.

Please let us know what happens.
