Dead Coin Battery

The most common reason your Fiat 500 key fob will not unlock or lock the doors is a dead battery.

If your remote started to show signs of weakening like a loss of range and stopped working completely it is likely that the battery is dead.

The battery in the key fob is held in place with metal clips for retaining. If the clips aren't secure, they could cause contact problems that will prevent your remote to receive power. Use a flathead screwdriver open the retaining clips and remove the old battery. Make sure you use an alternative battery that has the same kind of voltage, size, and specification as the original battery.
