If central locking cannot be activated with the remote control key - e.g. if the batteries are discharged - then the driver's door can be opened as follows:
Unlock the driver's door with the key blade in the door handle's lock cylinder. For illustration and more information, see Keyless drive - unlocking with the key blade .
When the door has been unlocked using the key blade and is opened, the alarm is triggered.
Deactivate the alarm by inserting the remote control key in the ignition switch.
