OK, update. I had the car scanned at the dealer/rapist today. No codes! They can't tell me why the light is on, but "suggested" an ignition switch replacement. I declined until they could be just a bit more definitive.

This pearl of wisdom cost me $65. And I didn't even get a free jar of vaseline!

Sigh. What the hell, I'm driving it.

Just bypass the system...
cut the two wires, solder in an equivalent resistor(*) on the wires going to the computer ($3)
never have security issue again and you don't need no more dam $40 keys anymore either. the $2 ones will work fine now
I did this last year to my wifes car and have had ZERO problem since. In doing so I did find the problem, one of the wires from thelock cyclinder had almost broken and sometimes wouldn't make a good connection.

I was wondering how you folks were starting your cars thou, with my wifes car, if the security light came on while driving it would run til you turned it off and then not start again until the security system would detect the key.

If it came on when you tried to start, you weren't going anywhere and you counldn't even retry starting for 5 whole minutes.

As I understand it from a number of posts here, you're correct on the "no start" with the light on. Yet my car starts and drives fine.

Weird.

How do you tell which resistor to buy? Your solution is beginning to sound quite feasible. I hate staring at the light.

take a multimeter to your key...that will tell you the resistor to buy.

or just pop the resistor out of your key and solder that one in there.
