How to Replace Key Fob Battery Hyundai Ioniq

Replacing your Hyundai Ioniq key fob battery is a quick and easy process that can save you time and money. Knowing how to do it yourself avoids a trip to the dealership or an auto locksmith. This guide will walk you through the steps involved in replacing the battery in your Hyundai Ioniq key fob, covering various models and potential issues you might encounter.

Finding the Right Battery for Your Hyundai Ioniq Key Fob

Before you begin, you’ll need to identify the correct battery type. Most Hyundai Ioniq key fobs use a CR2032 battery, a common type readily available at most stores. However, it’s always best to double-check your owner’s manual to confirm the specific battery required for your model year. Using the wrong battery can lead to malfunctions or even damage your key fob.

Step-by-Step Guide to Replacing Your Hyundai Ioniq Key Fob Battery

Replacing the battery in your Hyundai Ioniq key fob is generally straightforward. Here’s a step-by-step guide:

1. Locate the release button: On the side of your key fob, you’ll find a small release button. This button is often marked with a key icon or a small indentation.
2. Release the valet key: Press the release button and slide the valet key out of the fob. You’ll use this valet key to pry open the key fob casing.
3. Open the key fob: Carefully insert the valet key (or a small flathead screwdriver) into the slot where the valet key was located. Gently pry open the key fob casing. Be careful not to apply too much pressure, as this could damage the plastic.
4. Remove the old battery: Once the casing is open, you’ll see the CR2032 battery. Use your fingernail or a small tool to gently pry the old battery out of its compartment.
5. Insert the new battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side faces upwards.
6. Close the key fob: Align the two halves of the key fob casing and press them together until they snap shut.
7. Test the key fob: Try locking and unlocking your car to make sure the new battery is working correctly.

Troubleshooting Common Issues

Sometimes, even after replacing the battery, your key fob might not work. Here are some common issues and solutions:

• Key fob still not working: Double-check that the new battery is correctly installed and that the positive (+) side is facing up. If the battery is installed correctly, try reprogramming the key fob. Your owner’s manual should contain instructions on how to do this.
• Key fob casing damaged: If you accidentally damaged the key fob casing while replacing the battery, you might need to replace the entire key fob.
