2002 Olds Alero. Dash security light. I replaced ignition module. The car was working fine and the radio was left on while I was in the car.
When I went to start it, it wouldn't start. After letting it sit for awhile it finally started. We had it tested for codes and non came up. We replaced the ignition module and it started right up. Now it won't start again. I have read about this problem from other people on here and it seems as though it may be the ignition cylinder is bad.
I saw where you told a person you would send them some information on how to replace this. Is that something you could also send to me? I would really appreciate it and an email would be the best way so I could have it quickly.
Thanks for the tip/donation. It does sound like the ignition lock cylinder, which is also called the Passlock Sensor. Here is a pic of the release tab on the ignition switch. Remove the radio to access this.

Question: 2002 Oldsmobile Alero. Removed old blown engine new fuel assembly many new items to be exact. Has after market radio.I am wondering if and I hope I don't sound completely ignorant. But do I need to bring the car to a dealership with a new stock stereo and have them program it all? It at this time gas an after market deck. Could doing this replacement work if its gets programed?
Answer: Yes, is you install a new factory radio, you will need to get it programmed for your Oldsmobile. Also the theft will need to be learned or disabled. If you do not do these things, the radio will not work.
Be sure to get the correct radio for your car. Do not just get a GM factory radio. Many people do that and think it will work because it is a factory unit. But that is not the case. It MUST be for your model and year Alero or you will have nothing but trouble trying to get it to program and work properly. Expect to pay 1 hour labor charge to have that service done.
