Electronic immobilizer

Theft protection
The electronic immobilizer helps
protect your BMW motorcycle
from theft, and this enhanced
security is at your disposal with-
out any need for you to set pa-
rameters or activate additional
systems. The engine of a mo-
torcycle fitted with this electronic
immobilizer can be started only
with the keys that belong to the
motorcycle. You can also have
your authorized BMW Motorrad
retailer disable particular keys,
for example in the event that you
lose your keys. The engine can-
not be started with a key that has
been barred.
Electronics in key
The motorcycle's electronics
exchange certain continuously
changing signals with the elec-
tronics in the key; these signals
are specific to your motorcycle
and they are transmitted via the
ring antenna in the ignition lock.
The ignition is not enabled for
starting until the key has been
recognized as "authorized" for
your motorcycle.
A spare key attached to
the same ring as the igni-
tion key used to start the engine
could "irritate" the electronics,
in which case the enabling sig-
nal for starting is not issued. The
warning EWS is shown in the
multifunction display.
Always store the spare key sepa-
rately from the ignition key.
Replacement and extra
keys
Replacement and spare keys
are only available through an au-
thorized BMW Motorrad retailer.
The keys are part of an integrat-
ed security system, so the retail-
er is under an obligation to check
the legitimacy of all applications
for replacement/extra keys. If you
want to have a lost key barred,
you must bring along all other
keys that belong to the motorcy-
cle. A key that has been barred
