Is your Kia key fob starting to act up? You might be experiencing a decreased range, or perhaps it’s not responding as quickly as it used to. In most cases, the culprit is a low battery. Fortunately, replacing the battery in your Kia key fob is a straightforward process you can easily do yourself. This guide from keyfobx.com, your trusted automotive repair experts, will walk you through each step to get your key fob working like new again.
Kia key fobs, whether the folding key type or the smart key, rely on a small 3-volt lithium battery to operate. These batteries are designed to last for several years under normal use. However, like all batteries, they will eventually need replacement.
Let’s identify the type of key fob you have, as the initial steps vary slightly:
Folding Key
Smart Key
Once you’ve identified your key type, follow these simple steps to replace your Kia Key Fob Battery:
-
Open the Key Fob Casing: For both folding keys and smart keys, locate the small slot on the key fob casing. Insert a slim tool, like a small flathead screwdriver or a key, into this slot. Gently pry open the key cover. You should feel it separate easily without excessive force.
-
Access the Battery (Folding Key): If you have a folding key, after opening the cover, you’ll see a small retaining screw on the battery cover. Use a small screwdriver to loosen and remove this screw. Then, remove the battery cover to expose the battery. Smart keys typically do not have this additional screw and the battery is accessible once the casing is opened.
-
Remove and Replace the Battery: The battery you need is a CR2032 3V lithium battery. Carefully remove the old battery. Take note of the battery’s position before removing it – the positive (+) side should be facing upwards. Install the new CR2032 battery, ensuring it is placed in the correct orientation.
-
Reassemble the Key Fob: Carefully retrace your steps to reassemble the key fob. For folding keys, replace the battery cover and tighten the retaining screw. Snap the key fob cover back together until it is securely closed. Ensure all parts are firmly in place.
While changing your Kia key fob battery is generally simple, it’s important to handle it with care and heed these warnings and cautions:
WARNING
BUTTON BATTERY HAZARD
Lithium button batteries are dangerous if swallowed. Ingestion can cause severe or fatal injuries in as little as 2 hours. Always keep new and used batteries out of the reach of children. If you suspect a battery has been swallowed or placed inside any part of the body, seek immediate medical attention immediately.
CAUTION
- Delicate Electronics: Kia keyless entry systems are designed for long-term reliability but can be sensitive to moisture and static electricity. If you’re uncomfortable with the process or unsure about any step, it’s always best to contact an authorized Kia dealer or service partner for assistance.
- Use the Correct Battery: Using an incorrect battery type can cause your folding key or smart key to malfunction. Always ensure you are using a CR2032 3V lithium battery for replacement.
- Handle with Care: Avoid dropping your key fob, exposing it to water, or extreme temperatures (heat or direct sunlight). These conditions can damage the transmitter and lead to malfunction.
Proper Battery Disposal: Remember to dispose of the old battery responsibly. Improper disposal can be harmful to the environment and human health. Please follow your local regulations and laws for battery disposal.
If you encounter any difficulties or prefer professional assistance, Kia recommends visiting an authorized Kia dealer or service partner for your key fob battery replacement needs. However, for most Kia owners, changing the key fob battery is a quick and easy DIY task that can save you time and money.
