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

The tutorial video we are about to observe is applicable to multiple cars, including the Fiat Cronos, Fiat Argo, etc. It is quite easy to realize that the battery in the mentioned remote needs to be replaced, as you will no longer be able to activate or deactivate the central locking. That said, let's proceed: Extract the emergency key from the plastic shell of the remote, take a small flathead screwdriver, and pry at the joint of the two halves of the shell to open it, and finally, remove the battery from its slot and replace it.
