Central keys with remote control. They
specify the functions of the Key Mem-
ory. In the process individual functions
of your vehicle can behave differently
depending on the key used, see further
below.
You can mark the keys with remote
control using the color-coded decals
you received on taking delivery of the
vehicle
Each central key with remote con-
trol is equipped with an extended-
life battery, which is automatically
recharged in the ignition lock each time
you drive the vehicle.
If you have any central keys with remote
control that are not used on a regular
basis, you should therefore remember
to recharge these units by using them
to drive the vehicle for an extended
period at least once a year, refer to

Spare key for storage in a safe place,
such as in your wallet.
This key cannot be used to open the
locks for the luggage compartment lid
and glove compartment. This is an
advantage in a hotel, for example. The
key is not intended for constant use

How the system functions
Doubtless you have often reflected on how
great it would be if you could configure
your vehicle's various adjustment settings
to meet your own personal requirements.
BMW has designed several freely select-
able options into the vehicle during its
development. You can set these as desired
via the Control Center.
You can have up to four different basic set-
tings adjusted for four different persons for
the specific keys. The only requirement is
that each person uses his or her own cen-
tral key with remote control.
Additional keys are available at your BMW
center.
When your vehicle is unlocked with the
remote control, the vehicle recognizes the
individual user by means of a data
exchange with the key, and makes adjust-
ments accordingly.
To differentiate
Color-coded decals are provided to help
you distinguish the individual central keys
with remote control with their different set-
tings.
