A dead key fob battery is a frustrating experience, but the good news is that replacing it is a simple DIY task. In this guide, we’ll walk you through the steps to change the battery in your Hyundai key fob, so you can get back on the road quickly.
What You’ll Need
Before you begin, gather these few items:
- A small flathead screwdriver or a coin
- A fresh CR2032 battery (available at most grocery stores, pharmacies, and auto parts stores)
Locating the Battery Compartment
Hyundai key fobs can have slightly different designs depending on the model and year. However, the battery compartment is generally found in one of two places:
- On the back of the key fob: Look for a small notch or groove, which indicates the location of the battery cover.
- Inside the key fob: Some key fobs have a release button or latch that separates the metal key portion from the main fob body. The battery compartment is usually located within this section.
Step-by-Step Guide to Change Your Hyundai Key Fob Battery
Once you’ve identified the battery compartment, follow these steps:
- Open the battery compartment: If the battery compartment is on the back of the fob, use your fingernail, a coin, or the tip of a flathead screwdriver to gently pry open the cover. If it’s inside the fob, press the release button or slide the latch to separate the key sections and reveal the battery compartment.
- Remove the old battery: Carefully remove the old battery. Note the orientation of the positive (+) and negative (-) sides.
- Install the new battery: Insert the new CR2032 battery into the compartment, ensuring the positive (+) side faces up or matches the orientation of the old battery.
- Close the battery compartment: Align the cover and press it firmly until it snaps back into place. If the key fob was separated, reassemble the sections.
- Test the key fob: Try locking and unlocking your car doors to make sure the new battery is working correctly.
Still Having Trouble?
If your Hyundai key fob isn’t working even after replacing the battery, there could be other issues at play. Consider these possibilities:
- Key fob programming: Your key fob might need to be reprogrammed to your car. You can sometimes find instructions for this in your owner’s manual, or you might need to visit a dealership or an automotive locksmith.

- Other issues: Issues with your car’s battery or electrical system could also be preventing your key fob from working.
