B2723 PASS-Key Detection Circuit ???
Car runs, starts, no problems except this code won't go away. It is current too. My SECURITY light won't go off. I assume it is related to chip on the key, but like I said the car will start just fine.
Any ideas???

Interesting that you have this code as current and the car still starts. The diagnostic says this code will prevent the car from starting. You should clean the ignition lock cylinder with some contact cleaner and also inspect your key for corrosion on the resistor pellet. Try your second key and see what happens.
