Remove the steering column shroud first. Then you will be better able to find it. It is a small hole on the underside of the steering column housing, right under the area where the lock cylider is. You will need to use something very small to push the pin. The ignition lock cylinder has to the key inserted, and be turned to the "run" position before the pin will release and allow you to remove the lock cylinder

Why won't my key turn?


Ignition cylinder could be bad, it happens. Try turning wheel one way while trying, then try the other way. If still no then either your using the wrong key or cylinder is bad. You can replace it yourself as long as you don't have chip in your key...im pretty sure if that is case your better off having dealer do it. U can ask your local parts store about that.

How do i change the ignition switch on 89 camaro?


I have not change the switch on a Camaro, but I have changed them on other vehicles, such as a 1985 Chevy truck. It should be similar. You do have to remove the switch from the cylinder lock first. On my 85 truck, there was a ring that held the switch to the lock. I disconnected the wires (after making a drawing showing where each went) then screwed off the ring and removed the switch.
