Hyundai Santa Fe Key Fob
Notch At Top of Fob
Pry Open Two Halves
This automotive "how-to" guide was specifically written to assist owners of the 2nd generation 2007, 2008, 2009, 2010, 2011 & 2012 Hyundai Santa Fe SUV in replacing the button cell battery in the keyless entry system's key fob remote control.

Owners of other Hyundai or Kia vehicles such as the Tucson, Veracruz, Accent, Elantra, Veloster, Sonata, Azera, Genesis, Equus, Forte, Optima, Sorento, Rio, Soul, Sportage and Sedona may also find this guide to be helpful.

A new coin (A.K.A. "button", or "watch") battery for the key fob is part # CR2032 which can be purchased at any supermarket, pharmacy, Walmart, Target or online.

I recommend buying a 5 pack of CR 2032 3V batteries on Amazon for just a few bucks.

The only tool needed to replace the key fob battery is a small flathead screwdriver.

Install "+" Side Down
Pry out the old Panasonic CR2032 3V battery from the rear half of the key fob with the small flathead screwdriver.

Push in a new CR2032 battery into the socket with the "+" side of the battery facing down.

Line up the two halves of the key fob and gently snap them together until they rest flush with each other all the way around.

Test the new key fob battery by standing next to your Santa Fe and pushing the lock and unlock buttons.
