Is your 2021 Kia Soul key fob not working as reliably as it used to? A common culprit for weakened signal strength and inconsistent performance is a low battery. Fortunately, replacing the battery in your Kia Soul key fob is a straightforward process you can easily do yourself. This guide will walk you through each step to replace your 2021 Kia Soul key fob battery, ensuring you get back to hassle-free access to your vehicle.
Before we begin, it’s important to identify the type of key fob you have for your 2021 Kia Soul. Kia key fobs come in two main styles: the folding key and the smart key. While both use the same type of battery, the opening procedure varies slightly.
Identifying Your Kia Soul Key Fob Type
-
Folding Key: This type of key fob features a physical key blade that folds into the body of the fob.
-
Smart Key: The smart key is typically more rectangular and doesn’t have a visible, foldable key blade. It relies on proximity and button presses for vehicle access.
Tools You’ll Need
For both types of 2021 Kia Soul key fobs, you will need the following simple tools:
- Small flathead screwdriver or slim tool: Used to gently pry open the key fob casing.
- Phillips head screwdriver (for folding key only): Needed to loosen the battery cover screw on the folding key.
- CR2032 3V Lithium Battery: This is the correct replacement battery for your 2021 Kia Soul key fob. You can find these batteries at most drug stores, supermarkets, and online retailers.
Step-by-Step Battery Replacement Guide
Regardless of whether you have a folding key or a smart key, the battery replacement process is similar. Follow these steps carefully:
-
Open the Key Fob Casing: Locate the small slot on your key fob. Insert your slim tool or flathead screwdriver into this slot. Gently pry the key fob cover open. Take your time and avoid using excessive force to prevent damaging the casing.
-
Access the Battery (Folding Key): If you have a folding key, once the cover is open, you will see a small battery cover secured by a screw. Use your Phillips head screwdriver to loosen and remove this screw. Then, carefully remove the battery cover to expose the battery.
-
Replace the Old Battery: Carefully remove the old CR2032 battery. Note the orientation of the battery (+ side up or down) before removing it. Install the new CR2032 battery in the same orientation. Ensure it is securely placed in the battery compartment.
-
Reassemble the Key Fob: For folding keys, replace the battery cover and tighten the retaining screw. For both folding and smart keys, carefully snap the key fob cover back into place until it is securely closed. You should hear a click indicating it’s properly sealed.
Important Warnings and Cautions
Please take note of these important warnings and cautions during the battery replacement process and for general key fob maintenance:
WARNING: Button Battery Hazard
Lithium button batteries are dangerous if swallowed. They can cause serious internal injuries or death within hours. Keep new and used batteries out of reach of children at all times. If you suspect a battery has been swallowed, seek immediate medical attention.
CAUTIONS for Key Fob Handling and Battery Usage:
- Moisture and Static: Avoid exposing your key fob to moisture or static electricity. These can cause malfunctions in the keyless entry system. If you’re unsure about any step, consulting a Kia dealer is recommended.
- Correct Battery Type: Always use the correct CR2032 battery. Using the wrong type can damage your key fob.
- Prevent Damage: To prevent damage to your key fob, avoid dropping it, getting it wet, or exposing it to extreme temperatures or direct sunlight for extended periods.
Battery Disposal:
Dispose of the old battery responsibly according to your local regulations for electronic waste. Improper disposal can harm the environment and human health.
