Is your Kia key fob showing signs of a weak battery? Don’t worry, replacing the battery is a simple task that you can do on your own. In this guide, brought to you by Ace Locksmith, we’ll walk you through the process of changing your Kia key fob battery in just five easy steps. You’ll be back to using your key fob without any hassle. Let’s get started!

Step 1: Gather the Materials You’ll Need

Before you begin, make sure you have all the necessary tools and materials. You’ll need a small flat-head screwdriver, a replacement battery (usually a CR2032), and a clean cloth. Having everything ready will ensure a smooth process.

Step 2: Open Your Kia Key Fob

Take the small flat-head screwdriver and carefully insert it into the seam of your key fob. Gently twist the screwdriver to pop open the key fob’s case. Be cautious while doing this to avoid damaging the case or the internal components.

Step 3: Remove the Old Battery

Once the key fob case is open, you’ll see the battery compartment. Carefully remove the old battery from its slot. Pay attention to the orientation of the battery so you can place the new one correctly.

Step 4: Insert the New Battery

Take your new CR2032 battery and place it into the same slot with the correct orientation. Make sure the battery sits snugly in its place.

Step 5: Reassemble Your Kia Key Fob

With the new battery in place, carefully put the key fob’s case back together. Press the two halves of the case until they snap into place. You’ll hear a satisfying click when the case is securely closed.

How often should I change my Kia key fob battery?

It’s a good practice to replace the battery every 1-2 years, depending on usage. If you notice decreased range or sluggish response, it’s time for a battery change.

Can I use any type of battery for my key fob?

No, it’s recommended to use the specific battery type mentioned in your Kia’s manual, usually a CR2032. Using the wrong battery could damage your key fob.

Do I need to reprogram the key fob after changing the battery?

In most cases, no reprogramming is necessary. The key fob should work normally after a battery replacement.

Why is my key fob still not working after changing the battery?

Check if the battery is inserted correctly and if the case is securely closed. If the issue persists, consult your Kia dealership for assistance.

Can I change the key fob battery myself without voiding the warranty?

Yes, changing the key fob battery is a simple maintenance task and shouldn’t void your warranty. Just be careful while opening the case to avoid any damage.


Changing the battery of your Kia key fob doesn’t require any special skills. With just a few simple steps, you can have your key fob working like new again. Remember, having a functional key fob is essential for the smooth operation of your Kia.
