1990 Toyota Camry 1990 Toyota Camry 2WD, 2.0 L IGNITION SWI

Unable to remove the original ignition switch unit (lost original key) to replace it with a new one. \R\nThe Instructions with new ignition key specify that to remove the original unit, it must be in the "ACC" position. Problem is it looks like it's in the "Lock" position. Again, I don't have the original key, which is why I need to replace it. I removed the shroud from the sterring column to access the unit and remove the backend (whired unit). Please help with suggestions or point me to a source. Don't really want to go to a shop.
