2014 Charger Smart Key Fob

Slide Over Release Tab
This automotive maintenance tutorial was specifically written to assist owners of the seventh generation (2011, 2012, 2013, 2014 & possibly also the revised 2015) Dodge Charger sedan in changing the battery in the "Keyless Enter-N-Go" intelligent key fob for the keyless entry system.

Owners of other Chrysler, Dodge and RAM vehicles with similar key fobs such as the Town & Country, 300, 200, Avenger, Challenger, Journey, Dart, Durango, Grand Caravan, Ram C/V Tradesman and 1500 may also find these DIY instructions to be helpful.

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

The only tool needed to replace the battery is a small flathead screwdriver. You may also be able to use a coin, key, knife, nail file or any other similar item.

The first step is to turn over the smart key fob and locate the silver release tab for the emergency / backup metal ignition key.

Slide the release tab over and pull out the metal ignition key. Set the key aside in a safe place.

Gently Pry Out Old Battery
Insert the blade of the small flathead screwdriver in between the two halves of the key fob and gently pry them apart.

Pull out the old battery from the back cover of the fob with your fingernail or very carefully use the flathead screwdriver.

Try to avoid damaging or bending the metal electrical contacts.

The OEM battery for this 2014 Charger was a Panasonic CR2032 3V coin cell.

Re-insert the metal ignition key in to the fob.

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

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

Be sure to record the battery change in your vehicle's service records.
