From owners h/book

The system is an engine immobilization system. It is designed to help prevent the engine from being started unless a coded key programmed to your vehicle is used. Using the wrong key may prevent the engine from starting. A message may appear in the information display. If you are unable to start the engine with a correctly coded key, a malfunction has happened and a message may appear in the information display.
