Model: Citroen C3 FC, FN - Years 2002-2009
Part: Key

Learn how to replace the battery in the key fob of a Citroen C3. Take your key fob and press the release button of the metal key. Once the metal key is out, use a screwdriver to pry between the two covers of the key (in the space where the metal key fits). Pry until the covers separate, then separate one of the covers into two and extract the worn battery with a screwdriver. Take a new battery of the same type and voltage. Reassemble the covers of your key fob by pressing on the key case until you hear it click into place. Check the correct operation of the key fob.

How to Open the Bonnet on the Lancia Y

To open the bonnet on this vehicle, follow these simple instructions: first, open the driver's door and locate the lever positioned just below the dashboard, marked with an image of the vehicle with the bonnet open. Pull this lever towards you until you hear a "click" indicating the bonnet is released. Next, exit the cabin and stand in front of the bonnet to disengage the safety catch and complete the opening. To do this, slightly lift the bonnet, locate the yellow lever underneath, and pull it to the left to fully release and open the bonnet.
