Recognizing a Dying Key Fob Battery
Before you start digging for batteries, it’s a good idea to make sure that’s actually the problem. Here are some telltale signs your key fob battery is nearing its end:

- Intermittent Functionality: The key fob works sometimes, but not others, or you have to press the buttons multiple times to get a response.
- Warning Messages: Your Santa Fe’s dashboard might display a “Key Fob Battery Low” warning message.
What You’ll Need for the Replacement
- A new CR2032 battery (you can find these at most convenience stores, auto parts stores, and online retailers).
- A small flat-head screwdriver or a similar tool for prying open the key fob.
