The Immobilizer System - Monster 659 Owner's Manual

The Immobilizer system

For additional antitheft protection, the motorcycle is
equipped with an IMMOBILIZER, an electronic system that
locks the engine automatically whenever the ignition switch
is turned off.
Accommodated in the handgrip of each ignition key is an
electronic device that modulates an output signal. This signal
is generated by a special antenna incorporated in the switch
when the ignition is turned on and changes every time. The
modulated signal represents the "password" (which is
changed at each start-up) by which the ECU recognizes the
ignition key. The ECU will only allow the engine to start if it
recognises this password.
