How to Replace the Ignition Lock Cylinder of a 1997 Audi Cabriolet

1. Insert your key into the ignition slot and leave it in the 'Off' position.
2. Insert the paperclip into the slot just to the side of the key slot, and then turn your key to the 'Acc' position. The clip will keep the key from starting the car, and the key is then used to unlock the cylinder.
3. Pull on the key and the clip to remove the cylinder, and then place the old one down. Remove the key and then the paperclip.
4. Insert your key into the ignition slot of the new cylinder, and then push it into the place of the old one.
5. Insert the paperclip into the new cylinder once in place, and then turn the key to 'Acc' again to lock the cylinder into place.
