SOURCE: Need to replace ignition cylinder on 2000 Impala

Pop off the black ring around ignition lock small screwdriver willl do. Remove dashboard plastic to expose 2 bolts holding ignition assy. Can be tedious. IF you can turn the key turn it to Start. In the plastic housing there's a 1/4 by 3/8 hole. push in a screwdriver which will push in a button on ignition cylinder and allow you to slide it out. The hole is located at 4 o'clock if we agree that the 2 wiring harness plugs are at 6 o clock and its 1 and 1/4 inches below the face of ignition cylinder. If you dont feel that the screwdriver is pushing in that "button" rotate your key until it does. Then just slide the cylinder out.

The ignition cylinder will have to be removed and taken in to the dealership where they can recode it for you.If it is in the column the steering wheel has to be removed.If it is in the dash which I think yours is then the instrument panel has to be removed to remove the ignition cylinder.If you are not mechanically inclined then don`t attempt to repair this yourself.The other thing is that the theft deterrent system will have to be relearned or the vehicle will not start.The estimate I get is about 200 bucks.But it depends on the labor rate at the shop you go to.You should go to a dealership because they have the tools to repair the cylinder and I don`t know if an independent shop does or not.What you could do is call around and find out before you go.Hope this helps.Good luck.
