How to replace the remote battery in a Fiat 500

Model: Fiat 500 312 - Years 2007-2022
Part: Key

Easily replace the battery in the Fiat 500 key. Press button A as shown in figure 1 of the video, and move the metal insert (the key itself) to the open position. This will reveal the screw, which we see in the video as "C", using a small flat screwdriver. This will remove a sort of drawer where the battery is housed (a CR2032, which can be obtained for a few pounds even at a newsagent) that we will replace, being careful to respect its polarity. Now, we can reinsert the battery drawer back into the key, tightening the screw we opened earlier on the closed lock. Operation complete.
