This has been driving me nuts, as it usually does this on my way to work.

If car is cold or has been sitting for awhile, it will start right up. However if I pull into a gas station or shut the car off for a few minutes, and go to restart, security light will come on without fail almost everytime and not start for 3 mins. Then it will start.
Sometimes, the security light will come on as I'm driving, doesnt seem to run any different. I dont have a spare key or anything I could try differently. Would bypassing the lock cyinder with a resistor fix my problem?

 

yeah it sounds like vats. go a search for bypass vats and find the one that gives you step by step directions. if you cant find it lemme no i have it saved on my computer somewhere. i will have to find it and pm you with the link if needed. but let me no either way

 

I've seen the vats bypass, I'll start down that path. Thanks.

 

How many miles on the car? just curious, happened to me and my two other friends around the 100k point. We all have 2000-2002 cars too.

 

i found the link on my comp so here it is......

I have the same issue, but it doesn't stop my car from starting. The light just pops on when it feels like it.

 

Try cleaning your key.

 

It is probably the sensor on the key, if you have a spare key that is newer keep it on you. When you go to start the car and it does not start use the newer key and I bet it will start up.

 

I just had the same problem, tried both keys and tested the resistance. Both came in at 3.7 so im going to try the bypass!
