I have an 04 Trailblazer that has recently begun to not allow the ignition switch to go into the lock position and release the key. I don't know if this is related but I have just done some work on the brake system including a new booster and master. Also, the battery has been disconnected several times. This does not happen all of the time and I do not know of situations that change when it does and does not. Thanks for any help or suggestions.

 

Were you able to get any information about your issue/have it fixed yet? I just don't want to go off giving you all my info if no longer needed.
