What year is the truck??
Does the key move at all at this time, or still will not move??
The lock cylinder will come out if you can turn the ignition switch. You have to remove the bezel around the steering colunm, the plastic trim behind the steering wheel. There is a small hole on top of the ignition lock housing, you need to turn the ignition to the run position, move the shifter to drive(so the starter does not enegage) use a small pick to push in the small hole and turn the ignition to the start position. The lock cylinder should now come out.
You do not need to remove the steering wheel.
