No, an engine will not turn over with an activated immobilizer system. The immobilizer is a security feature designed to prevent the engine from starting unless the correct key (or fob) is used. If you're experiencing issues with your vehicle not starting and suspect the immobilizer, ensure you're using the correct key and it has no damage. For persistent issues, consulting a professional mechanic or your dealership is recommended to diagnose and resolve the issue effectively.
