Keys1 The master keys with remote control
determine the functions of the Key
Memory. Refer to page 53
There is an extended-life battery
in every master key which is
charged automatically in the steering
lock as you drive.
For this reason, if you have a master
key that is otherwise not used, use that
key at least once a year while driving for
an extended period. This will charge the
battery. Refer also to page 35.<
2 Spare key for storage in a safe place,
such as in your wallet. This key is not
intended for continuous use46cde059
3 Door and ignition key
The locks for the luggage compart-
ment lid and the glove compartment
cannot be operated with this key Ð
this is recommended for valet
parking, for instance
Replacement keysReplacement keys are available exclu-
sively through your BMW center. Since
the keys belong to a security system
(refer to "Electronic vehicle immobilizer"
on page 33), your BMW center is obli-
gated to be sure that a person
requesting a key is authorized to do so.
If possible, take all of the master
keys that belong to the vehicle
with you when you pick up your
replacement key.
When 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 elec-
tronic vehicle immobilizer to "learn" the
new key.<

Electronic vehicle immobilizer The key to securityYour 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
engine using any means other than the
special keys furnished with the vehicle.
Your BMW center can cancel the elec-
tronic system authorization for individual
keys (in the event of loss, for instance). A
deactivated key can no longer be used
to start the engine.46cde060
How the electronics workAt 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.<

Opening and closing Ð from the outsideUsing the remote control The remote control makes opening and
locking the doors of your vehicle very
convenient. Furthermore, it provides
two additional functions that can only
be executed by means of the remote
control:
>Switch on the interior lamps, refer to
page 36.
With this function, you can also
"search for" your vehicle Ð when
parked in an underground garage, for
instance.
>Open the luggage compartment,
refer to page 37.
The luggage compartment lid will
open slightly, no matter whether it
has been locked or unlocked.
The anti-theft system is also deacti-
vated simultaneously when you unlock
the vehicle, the alarm system is
disarmed, and the interior lamps are
turned on. When you lock the vehicle,
the systems are activated and armed,
and the lamps go off.
You can have a confirmation
message set to inform you that the
vehicle has been properly locked.<
Master keysKeys with remote control are master
keys. Refer to page 32.
Children might be able to lock the
doors from the inside. For this
reason, always take the vehicle keys
with you so that the vehicle can be
opened again from the outside at any
time.<460de494
Master keys that are used repeat-
edly are always ready for opera-
tion since the battery in the transmitter
is charged automatically in the steering
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 32.
To prevent unauthorized use of the
remote control, surrender only the door
and ignition key or the spare key (refer
to page 32) 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.<

twice: the first pull unlocks the door,
and the second one opens it.

all doors at once
or
>press the individual safety lock
buttons down. The fuel filler door
then remains unlocked. As an added
design feature to prevent the driver

of the vehicle, the driver's door safety
lock button will not engage as long as
the door is open.
Children might be able to lock the
doors from the inside. For this
reason, always take the vehicle's keys
with you so that the vehicle can be
opened again from the outside at any
time.<
