The key set
1Master keys with remote control.
They specify the functions of the Key
Memory. In the process individual func-
tions of your vehicle can behave differ-
ently depending on the key used, see
further below.
To differentiate, you can mark the keys
with remote controls using the color-
coded decals you received on taking
delivery of the vehicle
There is an extended-life battery
in every master key with remote
control which is charged automatically
in the ignition lock as you drive.
If you have any master 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 every six months, also
refer to page 28.<
2Spare key for storage in a safe place,
such as in your wallet.
The locks for the luggage compartment
lid and the hotel function, refer to
page 30, cannot be operated with this
key. This is an advantage in a hotel, for
example. The key is not intended for
constant use
Replacement keys
Additional or replacement keys are avail-
able at your BMW center.
Key Memory
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 mas-
ter key with remote control.
When your vehicle is unlocked with the
remote control, the vehicle recognizes the
individual key by means of a data exchange
and makes adjustments accordingly.
Examples of Key Memory functions
>Automatic adjustment of the driver's
seat
>Locking the vehicle after moving off
>When unlocking with the remote con-
trol, either unlock only the driver's door
or the entire vehicle
>Activating visual warning for PDC Park
Distance Control
>Resetting volume setting.
Central locking system
The concept
The central locking system is ready for
operation whenever the driver's door is
closed. This simultaneously engages and
releases the locks on the following:
>Doors
>Compartment in the front center con-
sole

via the remote control, the battery is dis-
