   Depress the lock plunger by inserting the straightened tip of a paper clip through the small hole on the face of the lock cylinder, to the right of the ignition key opening.

4. Step 4

   Turn the ignition key approximately 20 degrees in a counterclockwise direction while simultaneously depressing the lock plunger, then pull the ignition key out of the ignition switch.
