This automotive maintenance tutorial was specifically written to assist owners of the first generation (2012, 2013, 2014, 2015, 2016 and 2017) Hyundai Veloster in changing a dead battery in the key fob remote control for the keyless entry system.

Owners of other Hyundai or Kia vehicles such as the Elantra, Sonata, Azera, Santa Fe, Tucson, Accent, Ioniq, Genesis, Tiburon, ix20, i20, i30, i40, Veracruz, Optima, Cadenza, K900, Soul, Niro, Sportage, Sorento, Sedona, Rio, Forte and Spectra 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, Sony, GE, Energizer, Duracell and Maxell.

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

Pry Apart Two Halves
Lift Open Front Cover
Remove Remove Control
To prevent from scratching the plastic surfaces, I recommend either using a plastic pry bar tool or cover the tip of your screwdriver with a thin micro fiber cloth.

Insert the blade of the tool or screwdriver in to the slot on the top edge of the key fob near the "Lock" button.

Gently pry apart the two halves of the fob.

Remove the remote control unit (rubber button cover and green circuit board) out of the front half of the fob.

Slide Out Old Battery
Panasonic CR 2032 3V
Install New Battery


Gently push the old coin cell battery out of the holder.

Insert a new number CR2032 battery into the socket with the "+" positive side facing up towards you and the "-" negative side facing down.

If you use the screwdriver to push the old battery out of the socket, try to avoid bending the electrical contacts or scratching the green plastic circuit board.

Re-Insert Remove Unit
Snap Together Halves
Test New Key Fob Battery
Lower the remote control unit back in to the front cover of the fob.

Line up the two halves of the fob and gently pop them back together.

Make sure that the front and back cover of the fob are flush together at every edge.

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

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