Is your Hyundai key fob acting up? Before you head to the dealership, there’s a chance you might be able to fix it yourself with a quick battery swap. A dying battery in your key fob can lead to decreased range, unresponsive buttons, or even leave you stranded. This guide will walk you through the simple process of changing your Hyundai key fob battery, saving you time and money.
When Does My Hyundai Key Fob Battery Need Changing?
While Hyundai key fob batteries are designed to last a long time, they don’t last forever. Here are some common signs that it might be time for a replacement:
- Decreased Range: Are you noticing that you need to be closer to your car for the key fob to work? This is a classic sign of a weakening battery.
- Unresponsive Buttons: If you’re pressing the buttons on your key fob multiple times with no response, a dying battery is a likely culprit.
- Intermittent Functioning: Does your key fob sometimes work and sometimes not? This inconsistency usually points to a battery on its last legs.
- Dashboard Warning: Some Hyundai models will display a warning message on the dashboard when the key fob battery is low.

How to Change the Battery in a Hyundai Key Fob: A Step-by-Step Guide
Changing the battery in your Hyundai key fob is a straightforward process. Here’s a general guide, but keep in mind that specific steps might slightly vary depending on your Hyundai model year and key fob design. If you’re unsure, always consult your owner’s manual for model-specific instructions.
Tools You’ll Need:
- A new CR2032 battery
- A small flat-head screwdriver or a key
- Your Hyundai key fob
Instructions:
- Locate the Key Fob Release: Examine your Hyundai key fob. There’s usually a small button or switch you press to release the physical key.
- Remove the Physical Key: Slide the physical key out of the key fob.
- Open the Key Fob Casing: With the physical key removed, you should see a small slot or indentation on the side of the key fob. Insert the flat-head screwdriver or the tip of your key into the slot and gently pry open the casing. Be careful not to use excessive force, as this could damage the key fob.
- Identify and Remove the Old Battery: Inside the key fob, you’ll find the CR2032 battery. Carefully remove the old battery, noting which side is facing up (+ or -) for correct installation of the new one.
- Insert the New Battery: Place the new CR2032 battery into the compartment, ensuring it’s oriented the same way as the old battery.
- Reassemble the Key Fob: Align the two halves of the key fob casing and press them together until you hear a click, indicating they are securely closed.
- Reinsert the Physical Key: Slide the physical key back into its slot on the key fob.
- Test the Key Fob: Try locking and unlocking your car doors and using other key fob functions to ensure the new battery is working correctly.
