Is your 2021 Kia Sportage key fob not working as reliably as it used to? You might be experiencing a common issue: a low battery. Fortunately, replacing the battery in your Kia Sportage key fob is a straightforward process you can easily handle yourself. This guide will walk you through each step, ensuring you can quickly get your key fob back to its optimal working condition.
Kia key fobs come in two main styles: the folding key and the smart key. Both use a 3-volt lithium CR2032 battery, known for its long life, typically lasting several years under normal use. Knowing your key type will help you understand the slight variations in the battery replacement procedure.

Step-by-Step Guide to Replacing Your 2021 Kia Sportage Key Fob Battery
Whether you have a folding key or a smart key for your 2021 Kia Sportage, the battery replacement process is similar and requires minimal tools. Here’s a simple, step-by-step guide to help you:
-
Open the Key Fob Casing: Locate the small slot on your key fob. Insert a slim tool, like a small flathead screwdriver or a credit card, into this slot. Gently pry open the key fob cover. You may hear a click as the casing separates.
-
Access the Battery Compartment (Folding Key): If you have a folding key, after opening the cover, you’ll see a small retaining screw on the battery cover. Use a small Phillips head screwdriver to loosen and remove this screw. Then, carefully remove the battery cover to expose the old battery.
-
Remove the Old Battery: Gently take out the old CR2032 battery. Note the battery’s position – specifically, the positive (+) and negative (-) sides. This is important for correct installation of the new battery.
-
Install the New Battery: Place the new CR2032 battery into the compartment, ensuring it is in the same orientation as the old one you removed. The positive (+) side should typically be facing upwards.
-
Reassemble the Key Fob:
- (Folding Key): Replace the battery cover and tighten the retaining screw. Make sure it is snug but not overly tight.
- (Both Key Types): Align the two halves of the key fob casing and press them firmly together until they snap back into place. Ensure the casing is securely closed.
Important Warnings and Cautions
While replacing your 2021 Kia Sportage key fob battery is generally simple, it’s important to keep safety and functionality in mind. Kia provides the following warnings and cautions to ensure a smooth and safe process:
WARNING

Lithium button batteries are dangerous if swallowed and can cause serious internal injuries or even death within just two hours. Always keep new and used batteries out of reach of children. If you suspect a battery has been swallowed or placed inside any part of the body, seek immediate medical attention.

- Delicate Electronics: Your keyless entry system is designed for long-term use, but it can be damaged by moisture or static electricity. If you are uncomfortable with the battery replacement process or unsure about any step, Kia recommends visiting an authorized Kia dealer or service partner.
- Use the Correct Battery: Using an incorrect battery type can cause your key fob to malfunction. Always use a CR2032 3V lithium battery for replacement.
- Handle with Care: To prevent damage to your key fob transmitter, avoid dropping it, exposing it to water, excessive heat, or direct sunlight.
