Why did my security light come on and now my car won't start?

You need to put your key in the "on" position and you will notice that the Security light will be blinking. Keep the key in the On position until the Security Light stops blinking and stays on. This will take about ten minutes; after the security light stays on steadily, you want to turn the key to the off position and then try starting the car again. The purpose of this is to reset the passlock system that the Grand Am's come equipped with. It can be quite annoying, mine once left me stranded in the Walgreens Drive-thru when i shut off my engine. I'm planning on installing a remote starter and a bypass module to see if that will work. Good luck :)
