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
adjust or activate anything. This elec-
tronic immobilization system is
designed to reduce the susceptibility of
the vehicle to theft by making it impos-
sible to start the engine using any
means other than the special keys
furnished with the vehicle.
Your BMW center can cancel the elec-
tronic system authorization for indi-
vidual 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
damage the integrated electronic
circuitry. A damaged key can no longer
be used to start the engine.<
