How to Replace the Battery in a Hyundai Key Fob

Is your Hyundai key fob acting up? Before you head to the dealership, it might just be a dead battery. Replacing the battery in your Hyundai key fob is a simple task that you can easily do yourself at home, saving you time and money. This guide will walk you through the process step-by-step.

What You’ll Need:

A small flat-head screwdriver (or a coin, depending on your key fob model)
A fresh CR2032 battery (often referred to as a “coin” battery)

Finding the Battery Compartment

Most Hyundai key fobs have a separate battery compartment. Here’s how to find it:

Examine your key fob: Look for a small seam or groove around the edge of the fob. This usually indicates the location of the battery cover.
Locate the release button: There might be a small release button on the back of the fob. Press this button while gently prying open the battery cover.

Replacing the Battery

Open the battery compartment: Carefully insert the flat-head screwdriver (or coin) into the seam or groove, and gently pry open the battery cover.
Remove the old battery: Take note of the orientation of the positive (+) and negative (-) sides of the old battery.
Insert the new battery: Place the new CR2032 battery into the compartment, making sure the positive (+) side faces the same direction as the old battery.
Close the battery compartment: Align the battery cover and press it firmly until you hear it snap back into place.

Testing the Key Fob

Once the battery is replaced, test all the buttons on your key fob (lock, unlock, trunk release, panic button) to ensure it’s working properly. If some functions still don’t work, there might be a different issue. Check out our other resources for more information about specific Hyundai models:

Common Issues and Troubleshooting

My key fob still doesn’t work after replacing the battery.

Check the battery installation: Make sure the new battery is properly seated in the compartment and the positive (+) and negative (-) sides are correctly oriented.
Try a different CR2032 battery: Sometimes, a new battery may be faulty. Using a different battery can rule this out.
Inspect the key fob for damage: Look for any physical damage to the key fob or battery compartment that could be causing a problem.
Consider programming issues: In some cases, you may need to reprogram your key fob after replacing the battery. Consult your owner’s manual or seek professional help if needed.
