DRIVING -> Keys for Your Citroen C4 SUV First Generation (2004-2010)

K E Y S  
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. A  
long action with the key closes the windows.  
Note: With the vehicle stationary and the engine switched off, locking is  
signalled by the flashing of the interior locking control warning lamp.  
If any of the doors, or the boot, is open or not properly closed, central  
locking does not operate.  
Electronic immobiliser  
The ELECTRONIC IMMOBILISER device locks the engine supply sys-  
tem.  
The system activates automatically as the key is removed from the igni-  
tion.  
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. The metallic part of the key must be  
correctly deployed in order to ensure a successful dialogue.  
If the key is not recognised, starting is not possible.  
If this occurs, leave your vehicle immobilised and contact a CITROËN  
dealer.  
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 previously  
removing the ignition key.  
The key can be used to deactivate  
the front passenger’s airbag (see  
“Airbag”).  
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, the CITROËN dealer  
network can supply replacements.
