Key Card

Principle

The Key Card allows the vehicle to be unlocked
and locked, as well as started.
General information
The Key Card is available with Comfort Access
and Steptronic transmission. Depending on the
national-market version, the Key Card may not
be available.
A digital key that has already been paired with
the vehicle is installed on the Key Card. The digi‐
tal key must be activated via iDrive.
Before leaving the vehicle, deactivate the Key
Card or take the Key Card with you because the
active Key Card can be used to start the vehicle.
Always take the vehicle key with you to a service
appointment.
