When the "Lock vehicle" button is pressed, the remote control key  sends a radio frequency and infrared signal to the corresponding receivers in the vehicle. These receive the signal and transmit the information via the CAN bus to the electronic ignition/starter switch control module (N73)  . The electronic ignition/starter switch control module (N73)  checks the access authorization of the remote control key  . If the access authorization is valid, the electronic ignition/starter switch control module (N73)  sends the command "Lock" via the CAN bus. The PSE control module (combined) (A37)  receives the command and locks the doors pneumatically  .

Moreover, the interior switches, i.e. the interior central locking switch (N72/1s6)  and the remote trunk release switch (S20/1s6)  are locked.

If the remote control key is inserted into the electronic ignition/starter switch control module (N73) after  locking, the interior switches  are activated again. The status of the central locking is the same as after locking with the interior central locking switch (N72/1s6)  .

However, the vehicle is only unlocked again when a door is opened  .
