Electronic vehicle immobilizer

The key to security

Your BMW is equipped with a passive

anti-theft system. This electronic immo-

bilization system is designed to reduce

the susceptibility of your vehicle to theft

by making it impossible to start the en-

gine using any means other than the

special keys furnished with the vehicle.

Your BMW center can cancel the elec-

tronic system authorization for individ-

ual keys (for instance, in the event of

loss). 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.<
