Electronic Vehicle Immobilizer - BMW M COUPE Manual

Electronic vehicle immobilizer

The key to security
The electronic vehicle immobilization
unit increases the anti-theft protection
of your BMW – you do not have to ad-
just or activate anything. This electronic
immobilization system is designed to
reduce the susceptibility of the vehicle
to theft by making it impossible to start
the engine using any means other than
the special keys furnished with the ve-
hicle.
Your BMW center can cancel the elec-
tronic system authorization for individ-
ual keys (in the event a key is lost, for
instance). A deactivated key can no
longer be used to start the engine.
How the electronics work
At the heart of this system is an elec-
tronic chip which is integrated into the
key. The lock mechanism itself is actu-
ally a dual-function device, simulta-
neously serving as a communications
interface designed to allow the security
system to maintain a continuous stream
of variable, vehicle-specific signals with
the electronic circuitry in the key. The
system will not release the ignition, fuel
injection and starter unless it recog-
nizes an "authorized" key.
Force applied to the key can dam-
age the integrated electronic cir-
cuitry. A damaged key can no longer be
used to start the engine.<
