Default SECURITY light in my 2000 SE

Just this morning while driving down the road to work, my SECURITY light lit up and started beeping at me. I looked through the manual and didn't find any sort of explanation as to why this is happening. When I took the car to go to lunch, it happened again. Only this time it happened immediately after it did its instrument panel test. This happened again as I drove it back to work, but it shut off by the time I got back. The other times it just stayed on until I turned the car off.

Any ideas what this could mean?

My 93 was doing something very similar last year. If it works the same as mine, it'* trying to tell you there'* something wrong with the security system. Usually a sensor of some type. Mine turned out to be the 'tamper' switch on the trunk lock assembly. There'* a mechanical cable that comes from the lock barell assembly and goes to a switch mounted under the trunk lid. If someone uses a slidehammer to remover your lock, the security system engages. That'* where mine was broken. Right at the lock barrel. I'd look there first. If I'm right, great, if I'm wrong, forget this ever happened!

Well um, it'* NOT the same. I went to start it up to go home for the day...and nothin'. No sound of any kind. All I got was electrical power (the radio, dash instrumentation, etc.). My spider-sense tells me that'* the starter. Bummer.

Well spiderman, do you know what your security system does when it trips? It disables the ignition! You may have 2 totally unrelated problems, but I doubt it. A starter won't throw a security light. My money is on the security system, and that it disabled the PCM. Try your other key for starters, but I'm really betting on security.

Actually, I didn't know that it did that. You're probably right, then. When it comes to cars, I'm about as newbie as it gets! I did check the trunk lock though nothing seemed broken, worn, cracked, loose, detached, or anything. I guess we'll find out what the dealership says.

Thanks for the info!

As Will said, try your other key. It may be a bad resister in your ignition key (the little black thingy in your key). If that goes bad, you will have to replace the key with a new one from the factory. You can't just go to a hardware store and have one made, as it won't start your car.

Good luck.

Actually you can, if they're equipped for it (and a decent locksmith will be, too).

Specifically, they need a little resistance tester to identify which resistor pellet you have in your key (one of 15 possible values), and that tells them which key blank to use. The local Ace Hardware store in our town can copy PASSkey ignition keys; I can see their resistance-chip key tester sitting behind the counter. Don't know what they charge, but it'* probably less than the dealer.

You can download a PDF file from Bulldog Security that lists the 15 different PASSkey values here: http://www.bulldogsecurity.com/pdf/Model781.pdf (see table on Page 4)

A round of applause for willwren!

It was the security system, so in fixing it, they had to 'fix' all of my keys too. Remind me to ignore my spidey sense next time. Or at least LEARN something about my car. hehe.
