yesterday I disconnected my battery on my 97 camaro and upon connecting it back together my car has gone into some anti-theft mode. I have tried to lock and unlock the door and also used my keyless remote. Nothing works. When i try to start my car it wont let the started crank. If any on ecan help me get this problem fixed that would be huge

 

The only idea I have is have it tuned out of you computer. I don't know much about the VATS.
