Battery for Hyundai Key Fob: What You Need to Know

A dead battery in your Hyundai key fob can leave you stranded, but don’t panic! Replacing it is often a simple DIY task that can save you time and money. This guide provides you with all the information you need to get your Hyundai key fob powered up and working again.

What Kind of Battery Does a Hyundai Key Fob Use?

Hyundai key fobs typically use a small, flat, round battery known as a CR2032. This type of battery is widely available at most stores that sell batteries, including auto parts stores, supermarkets, and online retailers.

How to Replace Your Hyundai Key Fob Battery

Replacing the battery in your Hyundai key fob is usually straightforward, and many models don’t even require any tools! Here’s a general guide, but remember to consult your owner’s manual for specific instructions for your model:

Locate the Battery Compartment: Look for a small notch or groove on your key fob. This usually indicates the location of the battery compartment cover.
Open the Compartment: Some Hyundai key fobs have a small release button you can press to slide open the cover. Others may require you to gently pry it open with a flathead screwdriver or even your fingernail.
Remove the Old Battery: Take note of the battery’s orientation (positive (+) side up or down). Carefully remove the old battery, avoiding any contact with the metal contacts on the key fob unless absolutely necessary.
Insert the New Battery: Place the new CR2032 battery into the compartment, ensuring it matches the same orientation as the old battery.
Close the Compartment: Align the cover and press it firmly back into place until you hear a click, or it sits flush with the key fob.
Test the Key Fob: Try locking and unlocking your car doors and using the other key fob functions to ensure the new battery is working correctly.

Hyundai Key Fob Still Not Working After Battery Change?

If your Hyundai key fob isn’t working after a battery replacement, here are some potential causes and solutions:

Improper Battery Installation: Double-check that you’ve inserted the new battery correctly, with the positive (+) and negative (-) terminals aligned properly.
Battery Needs Reprogramming: Some Hyundai models require you to reprogram the key fob to the car after a battery change. Your owner’s manual will have instructions if this is necessary.
Other Key Fob Issues: A malfunctioning key fob might have other problems beyond a dead battery, like damaged buttons or internal components. You may need to consult a qualified automotive locksmith or Hyundai dealership for further diagnosis and repair.

“It’s always a good idea to keep a spare CR2032 battery handy in your car or glove compartment,” advises John Davis, Senior Automotive Technician at CarDiagTech Workshop. “That way, you’re prepared if your key fob battery dies unexpectedly.”
