Re: Passlock System

I have a 1997 Chevy Malibu 3.1L. No black chip on the key, no alarm system, no auto start system. I have experienced the problem of my Malibu not starting in that it will start and then die immediately. It did this once in 2004, once in 2006 and twice over the past month which now has me concerned. The only time I noticed the theft light was today. Even when I took the key out the theft light stayed on. As I sat for a bit I tried to start it a few times w/o success. After sitting for a bit I noticed the theft light went off. The key was in the ignition but in the off position. Once I noted the theft light was off I turned the key and the car started and stayed started.

I have read through the entire thread and I am a bit confused. I have read about bypassing by cutting a yellow wire while the car is running and about magnets in the lock cylinder being worn out. I know it will cost more to buy the part than bypass but will just replacing the ignition lock cylinder fix the problem just the same? Chiltons manual makes the removal/installation appear straightforward and the part looks like it is about $125 which is a reasonable price if I can do it myself and save labor at the dealer.

Also, how does the the old key still work after the ignition lock cylinder is replaced?
