Gathering the Necessary Tools
Replacing your 2017 Mercedes key fob battery requires only a few simple tools. You’ll need a small, flat-head screwdriver or a plastic pry tool to open the key fob casing, and a new CR2032 battery. These batteries are readily available at most electronics stores, pharmacies, and online.
