Sounds like the key and tumblers are in working order and there is damage to the cylinder keeping it from rotating to the run position. I would disconnect the battery to eliminate the chance of deploying the air bag. insert the key , then insert a strong flat blade screwdriver beside the key for some added torque (twist) . If that fails you can drill out the tumblers then the cylinder will rotate to run position and then depress retaining pin and remove cylinder. You can also drive the retaining pin in as much as you can with small center punch or nail set then using a slide hammer (dent puller) inserted into the ignition cylinder with a COARSE screw " bump " out the cylinder. NOTE: this may cause damage to the column because the retaining pin isn't fully depressed . And lastly here is the FORD procedure ...........
Ignition Switch Lock Cylinder - LOCK CYLINDER NON FUNCTIONAL
