Factory Security system

Weird thing happened to me this morning while changing the oil.

I got in the car to drive it up on the ramps and the car wouldn't start. (wouldn't even turn over...almost like a dead battery).

When I took the key out of the ignition, the security light stayed on. I then closed the door (I was still inside) and waited tried a couple of times to start it again. No luck.

I then got out of the car, shut the door and within 5 seconds, the security light went out.

Open the door, and the car starts fine.

I assume that I did something in the wrong progression for the security light to come on, however don't understand what that could possibly be.

Any information would be helpful.

You ignition switch has a set of contacts in it that connect to the resistor "pill" embedded in your key. These contacts can wear out and your Security system, VATS, doesn't see your key resistor.

any idea on a part number and difficulty to install?
