Electronic immobiliser
EWS
Protection against theft
The electronic immobiliser 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 immobiliser can be started
only with the keys that belong to
the vehicle. You can also have
your authorised BMW Motor-
rad dealer bar individual keys, for
example if a particular key goes
missing. The engine cannot be
started with a key that has been
barred.
In-key electronics
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 aerial in the ignition lock.
The ignition is not enabled for
starting until the key has been
recognised as "authorised" for
your motorcycle.
A spare key attached to
the same ring as the ig-
nition key used to start the en-
gine could "irritate" the electron-
ics, in which case the enabling
signal for starting is not issued.
The EWS warning appears in the
multifunction display.
Always keep the spare key sep-
arately from the ignition key.
Replacement and extra
keys
You can obtain replacement/extra
keys only through an authorised
BMW Motorrad dealer. The keys
are part of an integrated secur-
ity system, so the dealer is un-
der an obligation to check the
legitimacy of all applications for
replacement/extra keys. If you
want to have a lost key barred,
you have to bring with you all
the other keys that belong to
the motorcycle. A key that has
