If your pass key light is on but it still starts it basically means it has the hiv. It's just the first stage. Pretty soon the condition will progress and one day you will go to start her and she won't start. The light will stay on for about 2 minutes before going off during which time she won't start. When the light goes off she will crank right up. Usually this is just a taste of what's to come and you might not have any more occurances for a while. But then this will start occurring more frequently till one day she doesn't crank right up after the light goes off, and you have to wait an additional 2 minutes. This stage is getting close to full blown aids... metaphorically speaking of course.. where she won't start up at all. Included I have attached a graphic picture of a theft-deterent-modulectomy. Some might consider it a drastic procedure and go the route of just installing resistors. I decided to remove it cause I didn't feel comfortable leaving a diseased part in my other wise healthy car. She deserves better than that. Also just know you are not alone, everyone with a B-body must one day come to term with this dreaded disease.
