You need to be towed to your local Chevrolet Dealer for repairs. Hope that helps! Jim
Why would you expect that the engine would start with the security system engaged? There is a procedure for getting out of this in the owners manual or it might be found online, but a locksmith or the dealer is probably your best alternative. You could just call a mobile locksmith.
Don't waste your time on the magical relearn procedures that everyone talks about. They won't work in your situation! Jim
