Changing the Battery in a Fiat 500 Remote Key

Model: Fiat 500 312 - Years 2007-2024
Part: Key

Is the battery in your Fiat 500 key flat? Here’s how to change it. Take your ignition key and use a screwdriver to unscrew the securing screw after opening the metal keyring. Remove the flat battery from the battery holder (take the battery holder out of the key) with a screwdriver and get a new one of the same size and voltage. Reassemble the battery holder in the key remote, and screw in the tiny screw. Check the correct operation of the key remote by testing the door opening and closing buttons. Close the keyring inside the key remote.
