In-key security
The electronic immobiliser
helps protect your BMW motor-
cycle from theft, and this
enhanced security is at your
disposal without any need for
you to set parameters or acti-
vate additional systems. The
engine of a motorcycle fitted
with this electronic immobiliser
can be started only with the
keys that belong to the vehicle.
You can also have your author-
ised BMW motorcycle dealer
bar individual keys, for example
if a particular key goes missing.
The engine cannot be started
with a key that has been barred.
Function
An electronic component is
integrated into each of your
keys.
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 by the
ignition lock. Ignition, fuel sup-
ply and starter are not enabled
for starting until the key has
been recognised as "author-
ised" for your motorcycle.
