DRIVING -> Keys for Your Citroen C6 4 Door Second Generation (2016-2023)

KEYS  
CENTRAL LOCKING USING THE KEY  
A brief action with the key locks the vehicle.  
II  
Deadlocking: Central locking using the key  
A second action straightaway with the key deadlocks the vehicle. It is then  
impossible to open the doors from either inside or outside the vehicle.  
Note:  
With the vehicle stationary and the engine switched off, locking is sig-  
nalled by the ashing of the interior locking control warning lamp.  
If any of the doors, or the boot, is open or not properly closed, the cen-  
tral locking does not operate.  
ELECTRONIC IMMOBILISER  
KEY  
The key operates all the vehicle’s  
locks as well as the ignition.  
Note: For safety reasons, a buzzer  
will sound if you have switched off  
the ignition and opened the driver’s  
door without having removed the  
ignition key.  
The key can be used to deactivate  
the front passenger’s airbag. See  
"Airbags".  
ELECTRONIC IMMOBILISER  
The ELECTRONIC IMMOBILISER device locks the engine supply system.  
The system activates automatically as the key is removed from the ignition.  
All the vehicle’s keys contain an electronic immobiliser device.  
After you switch on the ignition, a dialogue starts between the key and the  
electronic immobiliser device.  
If the key is not recognised, you cannot start the vehicle.  
If this occurs, leave your vehicle immobilised and contact a CITROËN  
dealer.  
It is dangerous to operate the deadlocking when a person is in the vehicle as unlocking is impossible  
from the inside (without the remote control).  
The key number is on the label attached to the key.  
Should you lose your key or remote control, a CITROËN dealer can supply replacements.  
If you unlock your vehicle using the key because of a problem with the battery, be aware that  
opening/closing a door with the window closed can seriously damage the glass, even to the point  
of breaking it. See "Access".
