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.

    Loved my car until recently. Go to crank it and the anti theft light would be on. The first time I had it towed but since have learned the trick to leave the ignition on for 10 minutes or so to allow the system to reset. This works but is very inconvenient and has cost me two batteries. I finally took it to a Chev dealer but they want $450 to fix. This is totally ridiculous. If GM is aware of this problem and it is as common as it seems, they should fix it or at least make it affordable to be fixed.

    2002 Chevy Malibu 1 Owner - well maintained and then WHAM! After numerous times of a "no start" situation replaced battery. Driving down interstate w/80 year old mother in passenger seat - dashboard lite up like Las Vegas - car went dead had to coast across 2 lanes, an on-rampl onto shoulder! Indiana Roadside Assit rolled up immediately - thank goodness. Tapped on fuel pump w/stick and said: it's your fuel pump. Replaced fuel pump, $425 and 2-days (if that) later - it's doing it again. Only this time that pesky Anti-Theft has declared itself...and like the others, while I didn't realize it - I would throw the door open, turn the ignition to A/C - fiddle around with the ignition 2 - 3 X's - get frustrated - lit a cigarette and after half-a-smoke try the ignition and the DANG this usually starts. GM - Chvey - someone ought to have the butt whipped for doing us this way! I mean after all isn't it our tax dollars that bailed them out. I am a single, hard working adult female and not knowing if my auto will start is not what I call a sense of safety/security as their recent commercial for Chevy Pick Ups suggest they are famous for.

    The car wouldn't start, you had to have a special way to start it. 9 times out of 10 you would have to wait the 10 min. or so to let the anti theft code reactivate. Finally paid over $300 to replace the ignition switch.

    replaced cylinder but still happens periodically. Seems like an electrical issue cause other warning lights come on and off, blinker malfunction.

    the car will start occasionally and then will crank over and not start - at this time i show no spark - and than it will start like there is no problem. We are also having a problem with the anti theft system which started about a year ago. A friend told me that he read "if you wait five minutes and try to start the car it should start and it worked until now it seam the problem has grown.
    At this point I have taken it to a mechanic, who told me he can not fix it, that it is a dealer item because the ignition switch needs to be relearned.
