Question about 2003 Chevrolet Impala
I have had my 2003, 3.4, sedan style Impala since 2006. Every once in a while the SECURITY light comes on but the car is running fine (it will come on while I'm driving). I can shut the car off and turn it back over and the light will disappear. It had only come on a hand ful of times, since I have had it, but there appears to be nothing wrong while the vehicle is running. Any ideas on why this is occuring?
Disable the passlock permanently. It is not as hard as it seems. The dash assembly comes out easily and underneath the steering column there is a metal plate held in with some bolts that needs to come off. Once you get the bolt off there will be (3) wires running up the column (yellow, black and white) these will be tied or taped together. They are the only group of three coming up the steering column. START the car (vital to do this) and while the car is running snip the yellow wire in two. Tape the ends and put everything back together. Problem solved. I did this 10 months ago and have never had the problem again. I did 3 months of research finding out what a sorry system the Passlock is. The security orange or yellow dashlight will stay on but this does not affect anything.

I had the same problem and i had to have the whole security system replaced. it started off just the same way with just a light then maybe a year or less later my vehicle refused to start once i saw the light come on and i would have to sit with the key in the ON position for 10 minutes until the security reset itself. i suggest you take it to a chevy dealership and get it looked at. although there are plenty of people who have/had the same exact problem chevy will not cover it under warranty. cost me about 800 bucks to get fixed so i suggest you catch it early maybe there will be a quicker/cheaper fix for you.
