Yes, it works off of the key tho. Your key has either a chip in the shaft or a transponder in the plastic head that sends signal to the ignition/lock cylinder. The ignition then sends a signal to the TDM (theft deterrent module) also known as the "computer". The TDM then allows your starter to start. If there is a break anywhere in this system, the vehicle goes into security mode and shuts down the starter or injectors. The hard part is finding which area is causing the problem. Mechanics can change every part before "fixing" the problem. Ive had the best luck with just bypassing the entire system. Here is a link that explains the problem and a PERMINANT solution that you can do yourself. http://vatspasslockpasskeysecurityhelp.yolasite.com/

What do I do if I break my key and now it turns the vehicle over but won't start and the security light is on now


You have a fob with the key?
If the key is broken it won't be recognised by the security system. As such the immobiliser won't disable itself to allow you to start the vehicle, because your key isn't being recognised.

You need another key. You either have to go to the dealer or to an autoshop that can cut and program the key for you

Security system not letting van start


Security systems/immobilisers are a nightmare.
Usually it's because the key is not being recognised by the system.

Simple as it may sound, press the 'unlock' button twice - particularly when the key is in the ignition barrel.

Try replacing the battery in the key fob - the remote. Do the simple things first.

Put the key in the ignition. Turn it on/off 5-6 times (no need to try and start the engine..). On the final time leave the ignition switched on for 5 minutes. Hopefully, the system will 'recognise' the key and then allow you to start it.

Failing that, it sounds like a job for a auto electrician

1998 oldsmobile bravada security light flashing car wont start


This happens due to a failed or failing antitheft system. When the system cant communicate properly, it will disable your starter or injectors and show the SECURITY light. Go to this link for info and ways to beat this system yourself.

Programing a key fob


1. Perform a security system relearn.
2. Let the vehicle sit for more than 10 minutes with the key off.
3. Attempt to start the engine, leave the key in the run position monitoring the security system indicator.
4. After 10 minutes, the security indicator will change state.
5. Turn the key off and wait 10 seconds.
6. Attempt to start the engine. If the engine stalls, wait another 10 minutes with the key on.
7. After the second 10 minute timer has expired, turn the key off for 10 seconds.
8. Attempt to start the engine. If the engine stalls, wait another 10 minutes with the key on.
9. After the 3rd 10 minute timer has expired, shut the key off for 10 seconds.
10. The security system will relearn on the 4th starting attempt and the engine should start and run.
If this doesnt work, you may have a failure in your system. If the security light is on, and the reprogram doesnt work, you might want to look into bypassing that antitheft system.
