This morning I went outside and my car will not start. When I turn the key on the battery light flashes then the security light continues to flash repeatedly on the message center. On rare occasion while driving the SECURITY light would come on and remain solid until I stopped. This is the first time i've had the no start issue! I've tried 2 different key's, same problem. What can I do to get around this? Does anyone have a link to the passlock bypass if that would help? 05 impala base 3.4l.

I need this fixed today. Thanks very much

Might be your BCM. Try the security relearn first, if that doesn't work, my bet you will need a new BCM.

relearn worked, car started. i called and spoke to my brother who is a badass mechanic and GM pro and he said to use just a couple keys and ditch the 40 other keys on my keyring when driving the impala, as the weight pulling down on the key while in the ignition can cause SECURITY light issues, I'll see how well that works for now.

This has been happening to me alot. If you ever get stranded and it wont start disconnect your battery for 15 mins. Connect it again and car will start, will get you home but won't fix problem.

But if you are getting the problems, the ignition cylinder may already be worn. Saving the weight now won't do anything.
