1 Central Locking and Anti-Theft
NOJE-
A single unlock request from the driver's door with the FZV
key unlocks the driver's door only.
A second unlock request
unlocls the remaining doors and trunk. This feature can be
modified for individual users with the Key Memory capabil-
ities to activate all lock actuators simultaneously See Car
Memory
/ Key Memory later in this section.
Starting with 2000 models, the battery in the FZV ignition
Icey is recharged by the ignition switch ring antenna while
the ley is in the ignition switch.
Transmitter self-test (models to
1999)
Press buttons 1 and 2 at the same time. This starts ltey trans-
/ mitter self-test. Transmitter is OK when LED glows steadily
te{le"el for that particular key and illuminate an instrument
cluster message.

If batteries are replaced within one minute of removal, it is
not necessary to
periorm initialization.
Tlie state of charge of key batteries has no effect on elec-
tronic immobilizer (EWS) function.

for one second. If LED fails to illuminate, try replacing ltey~
batteries.
The state of charge of key transmitter batteries is monitored
by the
GM. Once the voltage level of the transmitter drops be-
low
4.5volts, the LED no longersignals transmitteroperation.
Convenience opening, initialization and self-testing are no
lonaer ~ossible. The GM will store a fault indicatina low bat-

4 1997 - 1999 models: Two lithium batteries are used to sup-
ply power to key transmitter. When replacement is neces-
sary, remove cover and two fasteners (arrows) from rear of
key to access batteries
NOTE-
If you replace the batteries within one minute, the FZV ley
will not require a new initialization procedure.
2000 and later models: FZV key battery is recharged by ring
antenna while ltey is in ignition switch. There is no need to re-
place ltey battery.
Car Memory 1 Key Memory
A number of features and functions can be customized to the
driver(s) preference. The identity of the vehicle user is provid-
ed by a
s~gnal from the keyless entry system (FZV).
Car Memory and Key Memory are actually two separate func-
tions, although they are marketed as a combined feature.
Car Memory
Pr'or ro new
veh c,e de very, the BMW scan roo (DISp us,
GTI or MOD C) is ~sed lo cooc ine driver preierences nro ine
appropriate control modules. Thereafter these choices can-
not be changed without
recoding with a BMW scan tool.
The functions that can be set using Car Memory include:
Alarm system (DWA) features such as armingldisarming
with
lkeyless entry (FZV), activation of tilt sensor or interior
sensor
lnterior light activation when central
locking is used
Convenience opening of
windows/sunroof
lnterior and external lighting preferences
Heating
I A/C preferences (IHKA)
Seat and mirror preferences (triggered by Key Memory)
Instrument cluster display units (for example: km vs. miles)

Central Locking and Anii-Theft
- If the starter engages, the following EWS inputs are function-
ing normally:
Ignition key
Code function
Transmission range switch or clutch position switch
Engine speed sensor
NO JE -
If a vehicle key is lost or stolen, the electronic authorization
for that key
can be cancelled using the BMW scan and di-
agnostic tools
DISplus, GTl or MoDiC.
Force applied to a ley can damage the electronic circuitry
in the key A damaged ley will not start the engine. In that
case, a new key should be purchased and initialized
by an
authorized BMW dealer.
