NO START: Security Light
Took the car out for a spin today. Weather was great and had a good ole time until i turned off the car. Tried to turn it on, nothing.?.! NOTE: while i was trying to start the engine would turn over as if it were going to start and shut off. Let it sit for several minutes and it started again.
Made it home pulled the codes; all historical (engine light was on until i cleared the codes). Wrote down codes just in case. Started the car several times, pulled codes and yet nothing, however SECURITY LIGHT remains. I have a new FOB and tried it... just in case because one of the historical codes had something to so with security.
My next step is to un-plug the battery to see if it'l reset and maybe give me a new code.
I'm clueless: I've search several forums; although it's mentioned no real answers/solutions have been given.
Thanks in advance for any solutions.

If it cleared when you cleaned it that sounds like a dirty resistor pellet is the issue.
The way the VATS works is that a current is passed through the resistor and is detected by the BCM. Once it confirms the value is correct it turns the fuel on and shuts off the security light. The resistor is specific for your car (15 different values available).
The other thing that can affect it is too much weight on the key ring. Some owners who carry around loads of items on their key ring have had issues. Its possible to loosen the key in the ignition barrel so that the resistor loses contact. It can be magnified if your ignition barrel is wearing as the car gets older.

Nothing other than the key and FOB
