Replacement keysare available exclusively through your
BMW center. Your BMW center is obli-
gated 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 the next page).
If possible, take all master keys
that belong to the vehicle with you
when you pick up your replacement
keys.
Whenever you receive a new
replacement key, turn that key to
position 2 in the ignition lock once (igni-
tion switched on) and then back. This
allows the electronic vehicle immobi-
lizer to "learn" the new key.<
New master key with remote control,
refer to page 144.

Electronic vehicle immobilizerThe key to securityThe electronic vehicle immobilization
unit increases the anti-theft protection
of your BMW Ð you do not have to
adjust or activate anything. This elec-
tronic immobilization system is
designed to reduce the susceptibility of
the vehicle to theft by making it impos-
sible 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 a key is lost,
for instance). A deactivated key can no
longer be used to start the engine.
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
damage the integrated electronic
circuitry. A damaged key can no longer
be used to start the engine.<

Remote control4. Press and hold down button 1 (see
illustration). Maintain pressure on
button 1 while rapidly pressing
button 2 three times in succession
within a period of 10 seconds
5. Release button 1. LED 3 flashes
slowly for a maximum of 10 seconds
6. The central locking system engages
and releases all lock mechanisms in
rapid succession to indicate that the
initialization procedure has been
successfully completed.
If the LED does not flash or if the
central locking system fails to respond,
the initialization procedure will have to
be repeated.
All additional master keys with remote
control for your vehicle (up to a
maximum of four units) must now be
initialized. Make sure that no more than
30 seconds is allowed to elapse
between the individual initialization
procedures. Repeat steps 4 and 5. The
central locking system will respond to
each initialization procedure as
descriped in step 6.
In the event of a system malfunction,
please contact your BMW center, who
can also provide you with replacement
keys.Turn each new master key into
ignition position 2 (ignition
switched on) and back again to allow
the electronic vehicle immobilizer (refer
to page 31) to recognize the new key.
To prevent unauthorized use of the
master key, surrender only the door and
ignition key 3 or the spare key 2 (refer
to page 30) for valet parking, for
instance.<
