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.<
