Your Kia Sorento 2021 key fob is a convenient tool for locking, unlocking, and starting your vehicle. It relies on a small 3V lithium battery to operate effectively. Typically, this battery will last for several years under normal use. However, like all batteries, it will eventually need replacing. This guide will walk you through the process of replacing the battery in your Kia Sorento 2021 key fob, ensuring you can maintain seamless access to your vehicle.
Kia Sorento 2021 key fobs come in two main styles: the folding key and the smart key. Both types utilize the same CR2032 3V lithium battery and follow a similar replacement procedure.
Types of Kia Sorento 2021 Key Fobs
It’s helpful to identify which type of key fob you have before starting the battery replacement.
Folding Key
The folding key has a traditional key blade that folds into the fob body when not in use.
Smart Key
The smart key is a more modern, keyless entry fob that may not have a physical key blade visible or readily accessible.
Step-by-Step Kia Sorento 2021 Key Fob Battery Replacement
Replacing the battery in your Kia Sorento 2021 key fob is a straightforward process you can do yourself. Here’s how:
- Access the Key Fob Housing: Locate the small slot on the side or bottom of your key fob.
- Open the Key Fob: Insert a slim tool, such as a small flat-head screwdriver or a coin, into the slot. Gently pry open the key fob cover. You may hear a click as the cover separates.
- Remove the Battery Cover (Folding Key): If you have a folding key, you may see a small retaining screw securing the battery cover. Loosen and remove this screw if present, and then carefully remove the battery cover. Smart keys usually do not have a retaining screw for the battery cover.
- Replace the Old Battery: Carefully remove the old CR2032 battery. Take note of the battery’s orientation (+ side up or down) before removal. Install the new CR2032 battery in the same orientation. Ensure the battery is securely placed in its compartment.
- Reassemble the Key Fob: Carefully snap the key fob cover back into place until it is securely closed. If you removed a screw for the battery cover on a folding key, replace and tighten it.
Important Warnings and Cautions
While replacing your Kia Sorento 2021 Key Fob Battery is simple, it’s important to be aware of these warnings and cautions:
WARNING: BUTTON BATTERY HAZARD
Kia key fobs use lithium button batteries. These batteries are dangerous if swallowed. Keep new and used batteries out of reach of children. Swallowing a lithium button battery can cause serious internal burns or death within just two hours. If you suspect a battery has been swallowed or placed inside any part of the body, seek immediate medical attention.
CAUTION:
- Moisture and Static: Keyless entry systems are designed for long-term use, but they can malfunction if exposed to moisture or static electricity. Handle your key fob with care and avoid damp environments when possible.
- Correct Battery Type: Using the wrong type of battery can cause your Kia Sorento 2021 key fob to malfunction. Always use a fresh CR2032 3V lithium battery for replacement.
- Avoid Damage: To prevent damage to your transmitter or smart key, avoid dropping it, getting it wet, or exposing it to extreme temperatures (heat or direct sunlight).
- Professional Assistance: If you are uncomfortable replacing the battery yourself or are unsure about any step in the process, Kia recommends visiting an authorized Kia dealer or service partner for assistance.
Battery Disposal
CAUTION: ENVIRONMENTAL AND HEALTH HAZARD
Improper disposal of batteries can harm the environment and human health. Dispose of used batteries according to your local regulations and laws regarding battery disposal. Many retailers that sell batteries also offer battery recycling programs.
By following these steps and precautions, you can easily replace the battery in your Kia Sorento 2021 key fob and ensure its continued reliable operation. Remember to handle batteries responsibly and seek professional help if needed.
