how do i get the ignition key cylinder out

TURN KEY ON(IF YOU CAN) REMOVE LOWER COLUMN TRIM. LOOK UNDER KEY THERE IS A HOLE ABOUT 3/16 DIA. INSERT PIN PUNCH OR THE LIKE PUSH IN ON LOCK PIN AND PULL CYL OUT. IF KEY WILL NOT TURN TO THE ON POSITION TOW TO SHOP. THE LOCK PIN CAN BE DRIVEN IN BUT YOU NEED TO KNOW HOW AND I CANT SHOW YOU ON HERE.
