If you cannot get the key to turn to ACC position, which is what allows the lockpin to depress fully to release the barrel, you will need to use a 1/8" drill bit and drill out the lockpin and then pull the barrel out. The new cylinder comes with its own lockpin, so it is not needed for the new cylinder.

You will need to remove the steering column cover first, pull the lock plate from under the interlock cable and remove the 2 bolts securing the ignition tumbler.
