I have made some headway on the ignition switch. I now have it at the position to insert the tool to remove the tumbler. I made the tool up, but for the life of me it won't release, and I never heard the click you are suppose to hear when the tool has released the probe inside. My lock has two holes. Some threads say on this model only tool in the top hole to release the tumbler. I have installed in both ways to no avail. Any help to release this tumbler would be appreciated. Thanks!!
