How to Replace the Key Battery for the Fiat Cronos

Model: Fiat Cronos 358s, X6S - Years 2018-2026
Part: Key

If you need to replace the battery in your remote key, proceed as follows: first, detach the plastic cover around the buttons. Then, use a sharp object to pry open and lift the back cover of the remote. Once the cover is removed, you will find the battery compartment underneath. To open it, you can also use the new battery to turn the cover counterclockwise. To extract the battery, use a sharp object again, take the new battery, and place it in the compartment. Close the small round cover by turning it half a turn to the right. Finally, reposition the back cover and the front mask.
