I tried going to work this morning and inserted the into the ignition of the car. The key would not turn to start. I tried different approaches such as wiggling the steering whell from one side to the other and trying to turn the key at the same time. That failed. I then placed a little lubricant to the key and in the ignition with same results. I am totally confused as to what the problem might besides needing to change the ignition switch and/or tumblers. Do you have an advised as to what the problem might be?
