The Immobilizer System; Keys - Ducati 749S 2005 Owner's Manual

The immobilizer system

For improved anti-theft protection, the motorcycle is
equipped with an IMMOBILIZER, an electronic system
that inhibits engine operation 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
E
signal is generated by a special antenna incorporated in the
switch when the ignition is turned on. The modulated
signal acts as a "password" and tells the CPU that an
"authorised" ignition key is being used to start up the
engine. When the CPU recognises the signal, it enables
engine start-up.

is also used to wipe off and re-program other black keys, if
needed.
Notes
The three keys have a small plate (1) attached which
shows their identification number.
