The passlock sensor in the ignition lock cylinder may fail causing an anti-theft system fault and a no start condition. Our technicians tell us that the ignition lock cylinder should be replace to correct this condition.

ya, it has been a problem . . . More so an inconvenience . . happens intermitently . .espencially when i'm in a hurry . . wonder if there is a way to just disconnect it or bypass the fuel cut off valve. . . is there any other alternative besides replacing the key cylinder?

SECURITY LIGHT flashed a few days before then one day car would not start, took it to shop and they diagnosed the faulty passlock sensor. Remedy was replacement.

My 2003 Grand Am sometimes wont start. I've noticed that when it wont start, the security light is flashing. To resolve the problem I have to leave the key in the ignition with it in the "ON" position for 12 minutes to reset the sensor. The sensor light wiull stop flashing when it is reset. Then I turn the key off and then back to start. It works every time but the 12 minute wait is a pain in the ass.

Today is the first day it happened. It is the first really rainy, wet day in a few months. The security light came on previously that day but I was able to start the car just fine three time. On the fourth start, nothing happened. I thought it might have been my starter but after reading a post discussing the blinking security light, I decided to follow the instructions. I put the key in the ignition and turned it to the acc position and waited 10 minutes until the light stayed on. I turned the key to the off position then back on and the car started. I'm happy it worked. I'm a little curious as to how often this is going to occur. I don't feel like putting any more money into the car. I think this will just be a nuissance until it corrects itself or I get a new car.

Usually happens when alarm is engaged when I get in my car and sit in the car for a minute or two. After car is re-unlocked with the fob, never has a problem
