Rebadged (Chevy) Lumina LS V6 2008
Hi,
I have a Chevy Lumina LS 2008 (re-badged VE commodore). I had my alternator changed 2 days ago due to a warning I got and also as confirmed with local shops here.
After the new alternator was installed and the battery connection was returned, had 'Security lockout vehicle data mismatch now.'
Other than this, the following symptoms were also seen:
1. Key cannot be removed from ignition
2. Transmission stick stucked as P as well
3. All lights on dash board turns on but head light and tail lights are off, with random messages on dashboard (low fuel, abs, etc...)
4. Now Engine won't start

The guys in the shop are having trouble finding out what caused this. Can anyone recommend or advise for similar case?
Thank you

Rebadged (Chevy) Lumina LS V6 2008
Hi,
Just got my car back yesterday. Guys from local shop(dealer) here, found that the BCM has gone bad. Cause as to why it went bad is not yet clear but somehow they had suspected a wrong procedure in the alternator replacement which could have caused electrical surges hitting the BCM and possibly corrupted the data in it. They had it replaced and said they had done reprogramming as well. So far all works well.
Hope this helps.

Can we assume you have used the radio on/off switch and that didn't make any difference?
