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.

The security light blinking is the problem, you must get control module scanned for fault codes to diagnose the issue or you can bypass the system if you understand basic electrical systems . Just google bypass passkey system.

If the security light is on you can try the 10 min. relearn procedure . Turn the key to run ( not start ) an leave the key on for ten min. If the light goes off in ten . min. turn the key off . Then start the vehicle . If the security light doesn't go off there is a hard fault an you will need to have it diagnosed by a repair shop that knows how .

"001 will be a transponder i reckon so its a dealer only job ,try the spare key first and still if no joy then call the breakdown truck

If the security light is on constant, this means that the actual computer of the antitheft system has failed. If it were flashing, this would indicate that the key or ignition was failing. The problem may not be the programming of the key, but more the computer that receives the signal.

If the chip or the "security" system for that matter is not working, you will see a light on the dash somewhere that says SECURITY. This light means that the key, ignition or TDM (theft deterrent module) is not working properly and shutting the starter off. Here is a link that explains the situation. http://vatspasslockpasskeysecurityhelp.yolasite.com/

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 :-)

try another key. if this doesnt work the wire in the tumbler assembly most likely broke and you will need it replaced. ( Ignition Switch)

Try this: attempt to start car. Leave key in "on" position for 10 minutes. Turn key off for 30 seconds. Attempt to start car. Leave key in "on" position for 10 minutes. Turn key off for 30 seconds. Attempt to start car. Leave key in "on" position for 10 minutes. Turn key off for 30 seconds. This lengthy proceedure is the pass-lock relearn. Should crank after this unless something is unplugged, body control module is bad, or other security issue.
