Principle
The vehicle is linked with the Connected-
Drive account of the vehicle owner.
BMW Digital Key lets you lock and unlock and
start your vehicle using a digital key.
The rechargeable battery of the smart-
phone has a sufficient charge. The neces-
sary minimum charge of the rechargeable
battery depends on the smartphone.
General information
BMW Digital Key availability and functionality
depend on vehicle equipment and national-
market version.
▷
Bluetooth must be activated on the smart-
phone for contactless unlocking and locking
using the digital key.
BMW Digital Key can be used with a compat-
ible smartphone or other compatible mobile
devices.
Enabling the main digital key
To unlock and start a vehicle with a compatible
smartphone, this function must be offered by
the smartphone manufacturer. The My BMW
app can be used to check if the smartphone
and vehicle are compatible and which func-
tions are supported.
Vehicle owner's smartphone is enabled as a
main digital key in the vehicle. The vehicle
owner must prove his authorization for the ve-
hicle for this purpose.
Proof of authorization can be started via the
My BMW App or using the activation code in
the corresponding smartphone function, e.g.,
the Wallet app.
A BMW ID or a driver profile with individual
settings can be assigned to a digital key.
When using a smartphone as a digital key, al-
ways carry a vehicle key or the activated Key
Card with you. This ensures access to the ve-
hicle, even in the event of a smartphone fail-
ure. It is also helpful to have the vehicle key
or Key Card with you if the vehicle needs to
be handed over to another person. You can
then hand over the vehicle key or the Key Card
instead of your smartphone.
Both vehicle keys must be located in the vehi-
cle to be enabled.
Follow the activation instructions in the Digital
Key menu, on the app, or on the control dis-
play.

Always take the vehicle key with you to a serv-
ice appointment.
