Operating requirements
▷ The BMW Connected app is installed on a
compatible smartphone.
▷ The smartphone battery is sufficiently
charged. The minimum battery charge re‐
quired depends on the smartphone in ques‐
tion.
▷ A digital key for the vehicle is installed on the
smartphone.
▷ BMW Digital Key is activated for the vehicle.
Activating BMW Digital Key
The vehicle owner must provide the Service
Partner with evidence of his/her authorisation for
the vehicle in order to use BMW Digital Key.
The vehicle owner sets a Digital Key Code with
the Service Partner so that other digital keys can
be enabled at a later date.
Acquiring digital keys
An initial digital key is provided in the BMW Con‐
nected app when the vehicle is purchased.
Additional digital keys can be acquired via the
BMW ConnectedDrive Store. Acquiring digital
keys may incur costs.
Digital keys have limited validity periods. The ex‐
piry date can be checked in the BMW Connec‐
ted app and in the vehicle.
If a digital key has expired, the vehicle can only
continue to be locked and unlocked for a limited
time and the number of engine starts is limited.
Corresponding messages are shown on the
Control Display.
Passing on digital keys
The vehicle owner can pass a digital key for
his/her vehicle on to another person via the BMW
Connected app.
When a digital key is passed on, a TAN transac‐
tion number is generated. Using this TAN and
the Digital Key Code, another person can regis‐
ter the digital key in the vehicle. This means the
driver can let someone else use the vehicle with‐

out having to be in the vicinity of the vehicle
themselves.
The TAN and the Digital Key Code should only
be passed on in person or via telephone.
The digital key that has been passed on can be
removed at any time in the vehicle or via the
BMW Connected app.
If a digital key has been removed via the BMW
Connected app, it can only still be used to unlock
and lock the vehicle for a limited time and the
number of engine starts is limited. Correspond‐
ing messages are shown on the Control Display.
As soon as the vehicle is used with a different
digital key or a remote control, the removed digi‐
tal key can no longer be used.
Registering digital keys in the
vehicle
In order to register a digital key, there must be a
remote control in the vehicle or an active digital
key belonging to the vehicle owner in the smart‐
phone dock.
If the digital key has been passed on by the vehi‐
cle owner, it may not be possible to meet this re‐
quirement. In this case, the Digital Key Code and
the TAN must be entered. The digital key that
has been passed on can be used to unlock the
vehicle even before it has been registered.
Place the smartphone with the digital key to be
registered in the smartphone dock.
Via iDrive:
1. "CAR"
2. "Settings"
3. "Doors/Vehicle access"
4. "BMW Digital Key"
5. "Add new digital key"
6. Enter the Digital Key Code and the TAN if ap‐
plicable.
Once the digital key has been registered, its
name appears in the list of digital keys.
