Is the light on all the time when you drive it? That may be the security system telling you there'* a problem. If your key cleaning or another key doesn't help, get back to me. I have something common for you to check

Try another key, too. Since the car lets you start it, I'd say it'* just a dirty connection in the key cylinder that stays good while you're actually twisting the key to start the car, then goes away after that.

Offhand, I can't think of any other faults that would light the Security light _while_ you're driving, although I suppose there must be something (will take another look in the manual when I'm home), but a dirty or worn key is the most common problem that produces this symptom.

Say, do you have any _other_ problems occurring at the same time, or just the warning light by itself?

My wife'* car just started doing this yesterday. The light has been on solid since then. I tried cleaning the key with rubbing alcohol and using a different key, and although it starts, the light is still on. What is the other common thing?

The light'* still on, I cleaned the key twice, and went and got a new key (needed one anyway), that little light is getting annoying. Maybe I can just bypass however it'* checking the key.... Will I need that when I finally put the remote start in anyway?

Yes you will, or the key will need to be in the run position (not secure or good for battery )

But do it with a kit, not just a resistor.

Did you try resetting the PCM (battery off for 30 min) to get rid of the light?

Dame. Remove the plastic retainers on the trunk lid carpet. Only a few in the middle, to about halfway back. (or the whole thing if you want). Follow the cable from the lock cylinder back to a connector with a wire or two going to it. Disconnect it (this is in the framework of the trunk lid). Now check for the security light. Good odds here, worth your time.

I don't have trunk lid carpet, only the really nice cars got that.... and there'* three wires going to what I assume is the trunk switch, and another two going to what I assume is the popper, Disconnecting them did nothing, But I did notice that the little "Inflatable Restraint" light flashes for a while after the rest of the lights go off.

The bulb prove-out and self-check on various systems take different amounts of time to finish, and I think the airbag system is one of the longer ones to finish, so that part of your description sounds normal.

Since the car lets you start it even though the Security light is on, you do _not_ have any problem with the ignition switch, so you can stop polishing your key now.

In this case the Security light is indicating a fault somewhere else in the security system, not the VATS circuit through the ignition, so as the others have said, you'll want to check the wiring to the trunk switch (it triggers the alarm if somebody pulls the trunk lock) and maybe also the pin switches at the doors and under the hood. (I'll have to check my manual on exactly what other components are in the network.)
