2021 Kia Seltos Key Fob Battery Replacement


The 2021 Kia Seltos is a popular compact SUV that comes equipped with a keyless entry system. The key fob allows you to lock, unlock, and start your vehicle with ease. However, like any battery-powered device, the key fob’s battery will eventually need to be replaced. In this article, we will guide you through the process of replacing the key fob battery for your 2021 Kia Seltos.

Step 1: Gather the Tools

Before you begin, make sure you have the necessary tools. You will need a small flat-head screwdriver and a replacement CR2032 battery. These items can be easily obtained from your local hardware or electronics store.

Step 2: Remove the Key

Start by locating the small button on the back of the key fob. Press the button to release the key. Once the key is released, set it aside in a safe place.

Step 3: Open the Key Fob

Take the small flat-head screwdriver and insert it into the groove on the side of the key fob. Gently twist the screwdriver to pry open the key fob. Be careful not to apply too much force, as you don’t want to damage the key fob.

Step 4: Remove the Old Battery

Inside the key fob, you will see the old battery. Use the screwdriver to carefully lift the battery out of its compartment. Take note of the battery’s orientation, as you will need to insert the new battery in the same way.

Step 5: Insert the New Battery

Take the new CR2032 battery and place it into the compartment, ensuring that it is oriented correctly. Gently press down on the battery to secure it in place.

Step 6: Close the Key Fob

Once the new battery is inserted, align the two halves of the key fob and press them together. You should hear a click when the key fob is securely closed.

Step 7: Reattach the Key

Take the key that you set aside earlier and slide it back into the key fob. Make sure it clicks into place.

Step 8: Test the Key Fob

Now that the battery has been replaced, it’s time to test the key fob. Stand near your vehicle and press the buttons on the key fob to ensure that it is working properly.


Replacing the key fob battery for your 2021 Kia Seltos is a simple process that can be done in a matter of minutes. By following the steps outlined in this article, you can ensure that your key fob remains functional and reliable.
