Is your 2021 Kia Sorento key fob starting to act up? A common culprit is a low battery. Fortunately, replacing the battery in your Kia Sorento key fob is a straightforward process you can often handle yourself. This guide will walk you through each step to get your key fob working like new again.
Kia Sorento key fobs come in two main styles: the folding key and the smart key. Both rely on a 3-volt lithium battery, typically a CR2032, which should provide years of service. However, when the time comes for a replacement, knowing how to do it yourself can save you time and a trip to the dealership.
Let’s get started with the battery replacement process. For both types of key fobs, the procedure is quite similar and requires only a few simple steps.
-
Accessing the Battery Compartment: Begin by locating the small slot on your key fob. Using a slim tool, like a small flathead screwdriver or even the tip of your car key, gently insert it into the slot and carefully pry open the key fob cover. Take your time to avoid damaging the plastic casing.
-
Removing the Battery Cover (Folding Key): If you have a folding key, after opening the main cover, you’ll see a small retaining screw on the battery cover. Loosen this screw. It’s usually a Phillips head screw. Once loosened, you can remove the battery cover to expose the battery. Smart keys may not have this screw and the battery compartment might be directly accessible after prying open the fob.
-
Replacing the Old Battery: With the battery compartment open, you’ll see the old CR2032 battery. Note the battery’s position, specifically which side is facing up (+ or -). Carefully remove the old battery. Install the new CR2032 battery, ensuring it’s placed in the correct orientation. Incorrect polarity can prevent the key fob from working.
-
Reassembling the Key Fob: Once the new battery is securely in place, reassemble the key fob in the reverse order of disassembly. For folding keys, replace the battery cover and tighten the retaining screw gently – don’t overtighten. Snap the key fob cover back together until it’s firmly closed.
While changing your 2021 Kia Sorento key fob battery is generally straightforward, it’s important to handle it with care and be aware of a few warnings and cautions.
WARNING
Lithium button batteries are dangerous if swallowed, especially by children. They can cause serious internal injuries within hours. Always keep new and used batteries out of reach of children. If you suspect a battery has been swallowed, seek immediate medical attention.
CAUTION
Key fobs are sensitive electronic devices. Avoid exposing them to moisture or static electricity, as this can cause malfunctions. If you’re uncomfortable with replacing the battery yourself, or if you encounter any issues, Kia recommends visiting an authorized Kia dealer or service partner for assistance.
Using the incorrect type of battery can also lead to key fob issues. Always ensure you are using a CR2032 battery for your 2021 Kia Sorento key fob. Furthermore, protect your key fob from damage by avoiding dropping it, getting it wet, or exposing it to extreme temperatures or direct sunlight.
Battery Disposal
Properly disposing of used batteries is crucial for environmental and health reasons. Do not simply throw old batteries in the trash. Dispose of them according to your local regulations for battery disposal. Many retailers that sell batteries also offer battery recycling drop-off points.
By following these steps and precautions, you can confidently replace the battery in your 2021 Kia Sorento key fob and ensure it continues to function reliably.
