Electronic vehicle immobilizer

The key to security

Your BMW is equipped with a passive

anti-theft system. This electronic immo-

bilization system reduces the likelihood

of your vehicle being stolen by making

it impossible to start the engine using

any keys other than the ones furnished

with the vehicle. Your BMW center can

cancel the electronic system authoriza-

tion for individual keys (in the event of

loss, for instance). A deactivated key

can no longer be used to start the en-

gine.

How the electronics work

At the heart of this system is an elec-

tronic chip that is integrated into the

key. The lock mechanism itself is actu-

ally a dual-function device. While the

engine is running, the circuitry in the

ignition key and the vehicle's electronic

system constantly exchange variable,

vehicle-specific signals. The system will

not release the ignition, fuel injection

and starter unless it recognizes 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.<
