Most of these fellows have owned the vehicle for awhile and are familiar with the "quirk" of this system, so, they have not mentioned it.

When the steering lock is engaged, the steering will frequently put pressure on the lock.........so..........turning the key is impossible because the key has no leverage to pull the locking pin out of the steering column.

We all have this technique........which is basically done without thinking.......to take the tension off the locking pin by attempting to turn the wheel slightly.......just a bit of pressure one way or the other (you don't know which side)........while simultaneously attempting to turn the key.

It's all done in one motion.........a bit of pressure on the wheel in one direction and attempt to turn the key.......if it doesn't go......repeat with pressure in the opposite direction.......to unload the lock and allow the cylinder to turn.

This may be your issue.......instead of the dreaded failed cylinder.
