KeysThe key set1 Master key with remote control
This key sets the functions for Key
Memory. Refer to page 55.
You can also identify individual keys
by applying the colored decals that
you received when accepting delivery
of your vehicle.
There is an extended-life battery
in every master key with remote
control that is charged automatically in
the ignition lock as you drive. For this
reason, if you have a master key with
remote control that is otherwise not
used, use that key at least once every
year while driving for an extended
period to charge the battery. Refer to
page 35 as well.<
2 Spare key for storage in a safe place,
such as in your wallet.
This key is not intended for constant
use
3 Door key
The locks for the luggage compart-
ment lid and the glove compartment
cannot be operated with this key –
this is recommended for valet
parking, for instance.
Replacement keysare available exclusively through your
BMW center. Since the keys are part of
a security system, vehicle ownership
must be checked before a replacement
key can be issued (refer to "Electronic
vehicle immobilizer" on page 33).
When picking up the replacement
key, take along all master keys
with remote control and spare keys
belonging to the vehicle. Whenever you
receive a new replacement key, turn
that key to position 2 in the ignition lock
once (ignition switched on) and then
back. This allows the electronic vehicle
immobilizer to "recognize" the new
key.<

Electronic vehicle immobilizer Central locking systemThe 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 the vehicle to theft
by making it impossible 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 of loss, 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 that 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.<
The conceptThe following can be unlocked or
locked simultaneously with the central
locking system:
>Doors
>Luggage compartment lid
>Fuel filler door
>Glove compartment.
The central locking system is ready for
operation whenever the driver's door is
closed.
The central locking system can be
operated
>from outside via the door lock and
using the remote control
>from inside by pressing a button.
If it is operated from inside, the fuel
filler door will not be locked (refer to
page 38).
If it is operated from outside, the anti-
theft protection is activated at the same
time. This prevents the doors from
being unlocked via the locking buttons
or the door handles. The alarm system
is also activated or deactivated.
