It's an electronic immobilizer, the key has a chip and there's a ring antenna around the key hole which sends a signal to the key and reads the key code before allowing bike to start. If you see EWS on your LCD screen, the bike will not start. Some of us are now carrying a spare ($82) for the latest version of the EWS ring antenna.
