Question about 2001 Oldsmobile Aurora
This is a very common problem on GM vehicles. The security system is known to fail. Basically when you insert your key, the system checks for certain OHMS resistance. If the system cannot get the correct signal from the key, it assumes the key is incorrect and goes into SECURITY lockout mode. (prevents hotwiring) This has been happening with GM;s for a very long time. There are ways to bypass this now. Read through this page for info, solutions as well.

I'm not sure yet if I've fixed it. But, I did find what seems to be a good solution. Others have installed a Passlock bypass module - as though they wanted a remotre start and report that this fixed it.
If your experts disagree or have a better fix, I'll pay for that info.

For the radio Im pretty sure you just need to call your dealer or go see them, they will take your VIN and give you a code to keep your after market stereo from kicking the theft lock.
The security light unfortunatly is a very common, and as it is just annoying right now, potentially big problem. The model Pass Key system in th 01 Olds Aurora tends to be defective in most of these cars. If the Security light, or DIC is flashing Theft fault system, you need to see your dealer. Chances are your secureity system is about to have some "Lock out" Malfunctions. These are no fun. Its when the Pass Key system detects a suspicious or uncorrect key trying to start car or someone is trying to enter car abnormally. Its actaully a very good feature when opperating properly. It usally lock the system for 3-10 minutes and the system resets and with the correct key you can start the car. The problem is that the little chips in the keys go bad causing the "lock out" to happen even when usuing the correct key. Anouther, less used key can work better, and if you start expieriencing lock outs, waiting to the system to reset usally works, but eventually those mthods will fail to and you will have to have it repaired. This system can also cause the "lock out" to occur while driving down the road.
Id get it checked and fixed before the neusance light become a real problem.
You can also consider a Bypass system that with completly go around the smart key system. They are inexpensive and effective and preventing issues with the Pass Lock. However you will not have the security settings from the Immobalizer (lock out) so it would be a easier target for joy riders. You will still have the theft deterant ability, that alarms if someone tried gaining entry to the car with out keys or proper entry methods.
Bypass systems are not full proof either and do wear out over time. I think they have far less issues than the securtity feature in the car and if the bypass fails and Lock Out occurs, simply get a new Bypass. Hope I helped a bit take care :-)
