This automotive maintenance tutorial was specifically written to assist owners of the first generation (2017, 2018, 2019 and possibly also the 2020 and 2021 model years) Chrysler Pacifica minivan in changing a weak or dead battery in the smart or "intelligent" key fob remote control for the keyless entry system and push button start system.

Owners of other FCA (Fiat Chrysler America) vehicles from Chrysler, Dodge, Jeep, RAM or Fiat such as the Town & Country, 300, 200, Charger, Challenger, Durango, Journey, Grand Caravan, Wrangler, Grand Cherokee, Compass, Renegade, Patriot, RAM 1500, RAM ProMaster City, Fiat 500 and Fiat 124 may also find these DIY instructions to be helpful.

The compatible replacement coin cell (also known as a "button" or "watch") battery is part number CR2032 which is available from various manufacturers such as Panasonic, Sony, Energizer, Duracell or Maxell.

The only tool needed to access and replace the key fob battery is a flathead screwdriver or a plastic pry bar tool.
