2015 Chrysler 200 Key Fob
Back Side of Smart Fob
Slide Release Switch
This automotive maintenance tutorial was specifically written to assist owners of the second generation 2015, 2016 and 2017 Chrysler 200 sedan in changing a dead battery in the smart (or "intelligent proximity") key fob remote control for the keyless entry and push button start systems.

Owners of other Chrysler, Dodge, Jeep, RAM or Fiat vehicles such as the 300, Pacifica, Town & Country, Avenger, Charger, Challenger, Journey, Dart, Durango, Magnum, Grand Caravan, Fiat 500, Fiat 124 Spider, Grand Cherokee, Renegade, Wrangler, Compass, Liberty, Patriot, ProMaster, 1500 and C/V Tradesman minivan may also find these DIY instructions to be helpful.

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

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

Metal Ignition Key Removed
Pry Apart Two Halves
Battery In Rear Cover
The first step is to turn over the key fob and locate the small grey / silver metal switch.

Slide the switch to release the metal emergency ignition key from the fob housing.

Remove the metal ignition key and set it aside in a safe place.

To prevent from scratching the plastic surfaces, I recommend either covering your screwdriver with a thin micro fiber cloth or use a small plastic pry bar tool.

Insert the blade of your tool in to the opening where the metal key used to reside.

Gently pry apart the two halves of the fob housing.

The battery holder is located on the back cover of the fob.

Remote Control Circuit Board
Lift Out Old Battery
Empty Battery Socket
Try to avoid scratching the green electrical remote control unit circuit board with the screwdriver.

Gently pry out the old battery from the socket on the rear cover of the fob housing.

With the old battery removed, you'll see the "+ Positive Side Down" note on the battery socket.


Panasonic CR 2032 3V
Install New Battery
"+" Positive Side Down
The OEM battery was a Panasonic CR2032 3 volt coin cell.

Push a new CR2032 battery in to the socket with the "+" positive side facing down and the "-" side facing up towards you.

Line Up Two Halves
Snap Together Key Fob
Flush At Every Edge
Line up the back cover and the front of the fob housing with each other.

Gently pop the two halves back together.

Make sure that the two halves of the fob are flush together at every edge.

Re-Insert Emergency Key
Stand Near Car With Fob
Test New Key Fob Battery
Replace the metal ignition key. It should "click" securely in to place.

To test the new battery, stand near your car and press the "Unlock" or "Lock" buttons on the key fob.

If the new battery is working properly, you should see the parking lights flash and also hear the door locks opening and closing.
