Is your 2020 Kia key fob not working as reliably as it used to? You might be facing a common issue: a dead or dying battery. Fortunately, replacing the battery in your Kia key fob is a straightforward process you can often handle yourself, saving time and money compared to a dealership visit. This guide will walk you through each step of replacing the battery in your 2020 Kia key fob, ensuring you get back to unlocking your car with ease.
There are two main types of key fobs you might have for your 2020 Kia: the folding key and the smart key. Both use a 3-volt lithium battery, typically the CR2032 model, which is known for its long lifespan, usually lasting several years under normal use. However, factors like frequency of use and environmental conditions can affect battery life.

Identifying Your Key Fob Type and Battery
Before you begin, it’s important to identify which type of key fob you have for your 2020 Kia. The images above illustrate the two common types:
- Folding Key: This type features a physical key that folds out from the fob.
- Smart Key: This key is typically larger and doesn’t have a physical key that folds out (though it may contain an emergency key inside). Smart keys often offer features like push-button start and remote start.
Regardless of the type, both usually use the same CR2032 battery. You can confirm the exact battery type by checking the owner’s manual for your 2020 Kia model or by opening your key fob and looking at the existing battery.
Tools You’ll Need
For a successful 2020 Kia Key Fob Battery Replacement, gather these simple tools:
- New CR2032 Battery: You can purchase these at most drugstores, supermarkets, and online retailers. Ensure it’s a fresh, high-quality battery for optimal performance.
- Small Flathead Screwdriver or Slim Tool: This will be used to gently pry open the key fob casing. A plastic trim tool is ideal to avoid scratches, but a small, thin flathead screwdriver will also work carefully.
- Phillips Head Screwdriver (for Folding Key, potentially): Some folding key models may have a small screw securing the battery cover.
Step-by-Step Battery Replacement Guide
Follow these steps to replace the battery in your 2020 Kia key fob:
-
Open the Key Fob Casing: Locate the small slot on your key fob. This is usually on the side or bottom of the fob. Insert your slim tool or flathead screwdriver into this slot. Gently twist or pry to separate the two halves of the key fob casing. Take your time and avoid forcing it to prevent damage to the plastic.
-
Access the Battery (Folding Key): If you have a folding key, you might see a small Phillips head screw securing a separate battery cover. Loosen and remove this screw with your Phillips head screwdriver. Once removed, the battery cover should be easily lifted off.
-
Remove the Old Battery: Carefully note the orientation of the old battery (+ side up or down). Use your fingertip or the edge of your slim tool to gently pry out the old CR2032 battery.
-
Install the New Battery: Place the new CR2032 battery into the battery compartment, ensuring the correct orientation (+ side should match the original battery position). Push down gently until it’s securely in place.
-
Reassemble the Key Fob:
- Folding Key: If you removed a battery cover screw, replace the cover and tighten the screw. Be careful not to overtighten.
- Both Key Types: Align the two halves of the key fob casing and press them firmly together until they snap back into place. Ensure there are no gaps and the casing is securely closed.
-
Test Your Key Fob: Try locking and unlocking your 2020 Kia with the key fob to confirm the new battery is working correctly.
Warnings and Cautions
While replacing your 2020 Kia key fob battery is generally simple, it’s important to be aware of these warnings and cautions:
WARNING
THIS PRODUCT CONTAINS A BUTTON BATTERY
If swallowed, a lithium button battery can cause severe or fatal injuries within 2 hours.
Keep batteries out of reach of children.
If you think batteries may have been swallowed or placed inside any part of the body, seek immediate medical attention.
CAUTION
- The keyless entry system transmitter is designed for years of use, but moisture or static electricity can cause malfunctions. If you’re unsure about battery replacement, Kia recommends contacting an authorized dealer.
- Using the wrong battery type can damage your key fob. Always use a CR2032 battery for your 2020 Kia key fob unless your owner’s manual specifies otherwise.
- Avoid dropping, wetting, or exposing your key fob to extreme heat or sunlight to prevent damage.
CAUTION
Improper battery disposal is harmful to the environment and human health. Dispose of the old battery according to your local regulations for electronic waste.
Troubleshooting
If your 2020 Kia key fob still doesn’t work after replacing the battery, consider these troubleshooting steps:
- Battery Orientation: Double-check that you installed the new battery in the correct orientation (+ side up or down as it was originally).
- Battery Quality: Ensure you are using a fresh, new CR2032 battery from a reputable brand. Old or low-quality batteries may not provide enough power.
- Key Fob Damage: If your key fob has been dropped, damaged by water, or exposed to extreme temperatures, internal damage might be the issue, not just the battery.
- Vehicle Issues: In rare cases, the problem might be with your vehicle’s receiver system, not the key fob itself.
If you’ve tried these steps and your 2020 Kia key fob still isn’t working, it’s best to consult with an authorized Kia dealer or service partner for professional diagnosis and repair. While DIY battery replacement is often successful, professional help might be needed for more complex issues.
