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.<

Central locking system Opening and closing – from the outsideThe conceptThe central locking system is ready for
operation as soon as you close the front
doors. The system engages and re-
leases the locks on the
>doors
>luggage compartment lid/tailgate
and rear window
*
>fuel filler door.
The central locking system can be
operated
>from outside via the driver's door lock
as well as via the remote control
>from inside via the central locking
system button.
The fuel filler door remains unlocked
when you activate the system from in-
side the vehicle (refer to page 42). The
anti-theft system is automatically armed
whenever you activate the central lock-
ing system from outside the vehicle.
The alarm system is also activated or
deactivated.
If looked from inside, the central locking
system unlocks automatically (only
those doors which were not locked
separately with the safety lock buttons)
in the event of an accident. Refer to
page 42. In addition, the hazard warn-
ing flashers and interior lamps come on.
With the keyOne turn of the key in the driver's door
lock unlocks the driver's door only.
Turning the key a second time unlocks
all of the remaining doors, the luggage
compartment lid/tailgate and the fuel
filler door.
You can have a signal set as an
acknowledgment message that
the vehicle is closed correctly.<390de627
Convenience operationYou can also operate the windows and
sliding/tilt sunroof via the door lock.
>To open: with the door closed, turn
the key to the "Unlock" position and
hold it.
>To close: with the door closed, turn
the key to the "Lock" position and
hold it.
Watch the closing process care-
fully and be sure that no one is
trapped by the closing motion. The win-
dows/sunroof stop moving immediately
when you release the key.< Manual operation (in the event of an electrical malfunc-
tion)
Turn the key all the way to the left or
right to unlock/lock the door.

Opening and closing – from the outsideWith the remote controlThe remote control makes opening and
locking the doors of your vehicle very
convenient. Furthermore, it provides
three additional functions which you
can only execute via the remote control:
>To switch on interior lamps, refer to
page 40
With this function, you can also
"search for" your vehicle, when
parked in an underground garage, for
instance.
>To open the luggage compartment/
tailgate, refer to page 41
The luggage compartment lid/tailgate
will open slightly, regardless of
whether it was previously locked or
unlocked.
>Panic mode
In case of danger, you can trigger the
alarm.
When the vehicle is unlocked, the anti-
theft system is simultaneously deacti-
vated, the alarm system is disarmed
and the interior lamps are switched on.
Locking the vehicle activates the anti-
theft and alarm systems and switches
the interior lamps off.
You can have a signal set as an
acknowledgment message that
the vehicle is closed correctly.<
Master keysKeys with a transmitter for remote
control are master keys. Refer to
page 36.
Since children might be able to
lock the doors from the inside,
take the vehicle's keys with you so that
the vehicle can be opened again from
the outside at any time.< 390us604
Master keys that are used repeat-
edly are always ready for opera-
tion, since the battery in the key is
charged automatically in the ignition
lock as you drive.
If it is no longer possible to unlock the
vehicle via the remote control, the
battery is discharged. Use this key
while driving for an extended period in
order to charge the battery. Refer also
to page 36.
To prevent unauthorized use of the
remote control, surrender only the door
and ignition key 3 or the spare key 2
(refer to page 36) when leaving the
vehicle for valet parking, for example.
In the event of a system malfunction,
please contact your BMW center. You
can also obtain replacement keys
there.<
