36nKeys
1 The master keys with remote control
determine the functions of the Key
Memory. Refer to page 60.
There is an extended-life battery
in every master key that is
charged automatically in the ignition
lock as you drive.
For this reason, if you have a master
key that is otherwise not used, use that
key approximately once every year
while driving for an extended period to
charge the battery. Refer also to
page 39.<
2 Spare key for storage in a safe place such as in your wallet. This key is not
intended for continuous use.

3 Door and ignition keyThe locks for the luggage compart-
ment lid/tailgate, rear backrest and
glove compartment cannot be oper-
ated with this key. This is useful for
valet parking, for instance.Replacement keys
Replacement keys are available exclu-
sively through your authorized BMW
center. Your BMW center is obligated
to ensure that a person requesting a
key is authorized to do so since the
keys belong to a security system (refer
to "Electronic vehicle immobilizer" on
page 37).
If possible, take all of the master
keys that belong to the vehicle
with you when you pick up your re-
placement key.
Whenever you receive a new replace-
ment key, turn that key to position 2 in
the ignition lock once (ignition switched
on) and then back. This allows the elec-
tronic vehicle immobilizer to "learn" the
new key. <

Electronic vehicle immobilizerThe 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 (in the event of loss, for in-
stance). A deactivated key can no
longer be used to start the engine.463de042
How the electronics workAt 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.<
