What's the FIAT 500X key fob battery type?

The FIAT 500x uses a CR2032 3 volt button cell battery in the key fob. Luckily, this is a very inexpensive replacement, as even the most "expensive" button cells typically go for a few dollars. While You may find some budget offerings online (especially when buying in quantity), You'll want to stick with a reputable brand; Your key fob is expensive equipment, and You don't want to trust it to cheap generics. The coSTSavings for buying a cheap generic brand is almost negligible, since CR2032s from the likes of Duracell or Energizer can be found for no more than two or three dollars. My advice, though, is to skip the auto parts store on this one; they often mark their batteries up a ridiculous sum, and You'll be able to save 50% or more buying on Amazon or at Walmart.
