Ok so I had some issues back last spring and the car went dead. Neither key would start it and the security light started flashing. Being new to the electronics on these cars I just did a starter bypass for the time being. I used it for about a month and then randomly one day it started with the key and never had anymore issues. The security light has stayed on throughout this entire time. So I finally got some time to tackle the bypass. I tested both keys and the read out 7 ohms. I ordered resistors. I used the correct resistor and the car fired up. Let it run and the security light never went off. Killed it and started it again same thing. So I removed the resistor and decided to try and start it with out the plug plugged it. It started right up and ran no issues. So now I am scratching my head. What is it? VATS? Key/Igniton? BCM? This has me stumped. Has anyone seen this before? Any help here would be greatly appreciated! Thanks in advance.
