INFORMATION

With the Introduction of Comfort Access 2.0, one of the major differences from the previous system is that now the vehicle constantly monitors the key location. This may cause the customer scenario described below.

Customer scenario:

The customer enters the vehicle and closes the doors. Then, the vehicle locks by itself (the alarm system also is armed). If the customer now presses the START-STOP button, the vehicle does not start. The customer holds the key against the steering column, but it is still not possible to start the engine. If the customer then exits the vehicle by pulling on the inside door handle, the alarm system is triggered

Pressing a button on the key deactivates the alarm system and unlocks the vehicle. Then, the vehicle can be started by pressing the START-STOP button.

This scenario occurs when the customer activates "Contactless locking/unlocking" via the iDrive and at the same time uses two keys (one in the vehicle, second one outside or close to the vehicle).

Explanation:

The customer enters the vehicle with the key; at the same time, the second key was moved outside and close to the vehicle. The vehicle therefore assumes that the key inside the vehicle should remain there. The system scans the vicinity of the vehicle, during which it is established that the key located outside the vehicle is no longer found (outside antenna range). The Comfort Access system assumes that the customer is moving away from the vehicle and secures (locks) the vehicle.

Securing (locking) the vehicle deactivates the key that is located in the vehicle which prevents the customer from starting the vehicle. To re-activate the key, the customer must exit the vehicle and operate the key (close/open door or push button on key). The vehicle can then be started.

This behavior is a normal characteristic of the system. Replacing parts or programming does not change how the systems operates. Inform the customer about this function. When using "Contactless opening/closing", the position of the second key must be observed; it should be outside the range of the vehicle.
