How to Replace a Chrysler Key Fob Battery

Young man with the keys at the car

Changing the key fob battery for your Chrysler Pacifica or Chrysler 300 is easier than you might think! In fact, it takes just a few minutes. Here are the things you’ll need: Your Chrysler key fob, thin but sturdy nail file, and a new battery. Ready to go? Follow the steps below to complete a battery replacement:

  1. First things first: Slide the tab on the face of the key fob to the side, and pull the key up and out.
  2. To separate the key fob (so you can access the battery), slide a thin nail file into the slot where the key was.
  3. Next, run the file down either side until the key fob can be separated into three pieces: cover, remote, and battery.
  4. The brand and type is shown on the front of the battery; write it down so you can order one (or a bulk set) online.
  5. Once you have your battery, pop out the old one.
  6. Pop the new battery inside, and snap the key fob pieces back into place.
  7. Slide the key back into its slot.
  8. You’re done!
