first make sure mounting bezel is removed then get a paper clip that fits into the small hole in the face of the ignition switch,next did you find the hole i'm talking about? good now insert the key that came with new ignition switch and turn it counter-clockwise (to the acc. position) take that paper clip you have and insert end into hole on face of ignition switch as that will depress a pin and contiue to turn key counter-clockwise and ignition tumbler will come out. good luck.
