EWS

Theft protection
The electronic immobilizer EWS
helps protect your BMW mo-
torcycle from theft, and this en-
hanced security is at your dis-
posal without any need for you to
set parameters or activate addi-
tional systems. The engine of a
motorcycle fitted with this elec-
tronic immobilizer can be started
only with the keys that belong
to the motorcycle. You can al-
so have your authorized BMW
Motorrad retailer disable particu-
lar keys, for example in the event
that you lose your keys. The en-
gine cannot 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
EWS
warning 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
