Awesome! One more piece of advise...please visit the dealership and see if your vehicle is covered under the massive recall campaign that was launched involving the ignition switch replacement. If it is covered, it would be replaced at no cost and the security module would need to be reprogrammed, which could solve your problem permanently. As I'm sure you are aware, the security system going into lockout mode is something that was caused by some sort of problem; either the key, the transponder/receiver or the module. I would advise checking the recall and / or having the codes scanned (even if the engine light is not on and the security light doesn't come back) before it happens again.
