The key operates all the vehicle’s locks as well as the ignition.

For any modification concerning the keys it is essential to contact a CITROËN Advice

For any modification concerning the keys it is essential to contact a CITROËN dealer taking all of the keys in your possession with you.

Central locking using the key

A brief action with the key locks the vehicle.

Central deadlocking using the key

A second action straight away 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 key contains a coded electronic chip. When switching on, the code must be recognised to allow the engine to be started.

This electronic immobiliser locks the engine management system a few seconds after switching off the ignition, and prevents unauthorised starting of the engine.

If the key is not recognised, starting is not possible.

If this occurs, leave your vehicle immobilised and contact a CITROËN dealer.

It is dangerous to deadlock the vehicle when someone is inside as unlocking from the interior is impossible (without the remote control).

In the event of loss of the keys go to a CITROËN dealer with proof of ownership of the vehicle.

The CITROËN dealer network will be able to recover the key code and the transponder code to order replacement keys.
