How to Change a Hyundai Key Fob Battery

If your Hyundai key fob is acting up – locking and unlocking doors intermittently or not responding at all – it’s probably time to replace the battery. Luckily, this is a quick and easy fix you can do yourself, saving you a trip to the dealership. In this guide, we’ll walk you through the steps of How To Change A Hyundai Key Fob Battery for various models.

What You’ll Need to Change Your Hyundai Key Fob Battery

Before we begin, gather the following items:

A small flat-head screwdriver: This will be used to pry open the key fob.
A new CR2032 battery: This is the standard battery size for most Hyundai key fobs.

Pro Tip from John Carter, Senior Automotive Technician at Car Care Central: “Always use a high-quality CR2032 battery for your Hyundai key fob. Cheap batteries may leak or die quickly, leaving you stranded.”

Steps to Change Your Hyundai Key Fob Battery

While the exact steps might vary slightly depending on your Hyundai model, the general process is the same. Here’s a step-by-step guide:

Locate the key release button on the back of your key fob. This is usually a small button or switch.
Press the key release button and slide out the metal key. Set the metal key aside.
Identify the seam or groove around the edge of the key fob. This is where the two halves of the fob are joined.
Carefully insert the flat-head screwdriver into the seam and gently pry the two halves apart. You may hear a slight click as the fob separates.
Once the key fob is open, locate the old battery. It will be a small, round, silver battery.
Note the orientation of the positive (+) side of the battery.
Gently remove the old battery. You can use your fingernail or the flat-head screwdriver to carefully lift it out.
Insert the new battery, making sure the positive (+) side is facing the same direction as the old battery.
Align the two halves of the key fob and press them firmly together until they snap back into place.

Testing Your New Hyundai Key Fob Battery

After replacing the battery, test all the buttons on your key fob to ensure it’s working properly. If the buttons still don’t respond, double-check that the new battery is properly installed and that the positive (+) side is facing the correct direction.

Common Issues When Changing a Hyundai Key Fob Battery:

Having trouble opening the key fob: If you can’t separate the two halves of the fob, try a different spot along the seam or use a thinner flat-head screwdriver.
The key fob still doesn’t work after replacing the battery: Ensure the battery is properly installed and the positive (+) side is facing the correct way. If the problem persists, there might be another issue with the key fob itself, and it’s best to consult your Hyundai dealership or a qualified automotive locksmith.
