[]Hello, everyone. I need help to a problem with my lumina. Today, every since my security light comes, some times my car will start and some times it wont. Sometimes, if I let it sit for about a minute or two, it will start right on up. Other times, I have to jump it off. I had my battery and alternator tested, and both came back good. I just had lot OF darn work put into and it's still acting up! I had an anti-theft box put in and the security light still comes on somtimes. HELP!!!

 

Read the manual about the PASS II key, there is a chip in the key and there might be something wrong with it. Read the pass 2 key part and the security part. Maybe that might help.
