Take the glove box door out of the car. This will make it a little easier to remove the latch. notice the position of the latch (open position)
Now with your finger click it shut.
Turn the chrome knob counterclockwise until it stops. Remove the two latch screws and rotate the latch in the door 180 degrees. This will gain you access to the small square hole in the lock barrel.
With a small flat blade screw driver, insert in square hole and press down on the release.
While holding down on the release, insert a small wire in the tiny hole in the chrome knob (floral wire works great).
Take out the screw driver. The wire holds the release catch in the barrel while you pull the chrome knob out. Do not remove the wire for you'll need it to reinstall.
