Why is My Hyundai Key Fob Not Working?

Before we dive into the how-to, let’s quickly address some common reasons why your Hyundai key fob might be malfunctioning. While a dead battery is the most common culprit, other issues could include:

Key Fob Programming: Sometimes, the key fob can lose its programming. This requires a trip to a dealership or specialized locksmith.
Internal Damage: Physical damage or water exposure can damage the key fob’s internal components.

Gathering Your Supplies

You’ll only need a few things to change the battery in your Hyundai key fob:

A new CR2032 battery
A small flathead screwdriver or a similar tool (A key or a thin butter knife can sometimes work in a pinch!)
Optionally, a small plastic pry tool can be helpful.

Step-by-Step Guide to Change Battery in Hyundai Key Fob

Here’s a general guide for changing the key fob battery, though specific steps might vary slightly depending on your Hyundai model.

Locate the Release Button: On the side of your key fob, you’ll find a small release button. This is often near the metal key ring.
Release the Metal Key: Press the release button and gently slide out the metal key.
Open the Key Fob: Use your flathead screwdriver or pry tool to carefully pry open the key fob casing. Start by inserting the tool into the slot where the metal key was removed. There’s usually a small notch that’s perfect for this. Work your way around the edge of the key fob, gently separating the two halves. Be careful not to apply too much force, as you could damage the plastic.
Remove the Old Battery: Once the key fob is open, you should see the CR2032 battery. Use your screwdriver or pry tool to gently lift the old battery out of its compartment.
Insert the New Battery: Place the new CR2032 battery into the compartment, making sure the positive (+) side is facing upwards, just like the old battery.
Close the Key Fob: Carefully align the two halves of the key fob and press them together until they snap shut.
Reinsert the Metal Key: Slide the metal key back into its slot.
Test the Key Fob: Try locking and unlocking your car to ensure the new battery is working correctly.

Common Issues and Troubleshooting

Key Fob Still Not Working: If your key fob isn’t working after replacing the battery, try reprogramming it. Consult your owner’s manual for specific instructions. If reprogramming doesn’t work, there might be internal damage, requiring professional assistance.
Difficulty Opening the Key Fob: If you’re having trouble opening the key fob, try a different tool or adjust your angle. Be gentle to avoid breaking the plastic. For the 2013 Hyundai Accent key fob battery replacement, refer to our detailed guide for model-specific instructions.
