How to Replace the Key Shell on the Citroën C4?

Model: Citroen C4 MK 1 - Years 2004-2010
Part: Key

To replace the key shell on the Citroën C4, press the button to extend the key and remove the retaining pin located in the small hole at the base of the key, detaching the key itself. Once the new key is inserted, you can also replace the casing by prying inside the groove formed between the two halves. By removing the top part, you can slide out the chip and the battery, placing them inside a new shell and sealing everything, also securing the key with the previously removed pin.
