Modern Kia vehicles come equipped with convenient key fobs, allowing for keyless entry and ignition. These fobs, whether the folding key or smart key type, rely on a small 3-volt lithium battery to function. Typically, these batteries are long-lasting, often enduring for several years. However, like all batteries, they will eventually need replacing. Knowing how to change your Kia key fob battery yourself can save you time and a trip to the dealership. This guide provides a step-by-step approach to replacing the battery in your Kia key fob, ensuring you can maintain the convenience of your keyless entry system.
To begin, it’s helpful to identify the type of Kia key fob you have, as the battery replacement process is slightly different for each.
Identifying Your Kia Key Fob Type
Kia key fobs generally come in two main types: the folding key and the smart key. The folding key has a physical key blade that folds into the fob, while the smart key is typically larger and designed for advanced features like remote start and push-button ignition without needing a physical key insertion.

Once you have identified your key fob type, you can proceed with the battery replacement. The following steps outline the general procedure applicable to both types, with specific notes where differences occur.
Step-by-Step Guide to Changing Your Kia Key Fob Battery
Changing the battery in your Kia key fob is a straightforward process that can usually be done with a few simple tools.
-
Accessing the Battery Compartment: For both folding and smart keys, locate the small slot on the key fob casing. This slot is designed to allow you to gently pry open the key cover. Insert a slim tool, such as a small flathead screwdriver or a plastic trim tool, into this slot. Gently twist or pry to separate the key fob cover. Be careful not to apply excessive force to avoid damaging the casing.
-
Opening the Battery Cover (Folding Key): If you have a folding key, once the main cover is open, you will likely see a small retaining screw securing the battery cover. Use a small Phillips head screwdriver to loosen and remove this screw. After removing the screw, the battery cover can be taken off, exposing the battery. Smart keys may not have this additional screw and cover; the battery might be directly accessible once the main casing is opened.
-
Replacing the Battery: The battery used in most Kia key fobs is a CR2032 3-volt lithium battery. Carefully remove the old battery. Note the orientation of the battery before removing it – usually, the positive (+) side faces upwards. Install the new CR2032 battery, ensuring it is placed in the correct position, matching the orientation of the old battery.
-
Reassembling the Key Fob: After replacing the battery, reassemble the key fob in the reverse order of disassembly. For folding keys, replace the battery cover and tighten the retaining screw if applicable. Snap the key fob covers back together, ensuring they are securely closed.
While changing the battery is generally simple, Kia recommends visiting an authorized dealer or service partner for key fob battery replacement. This is partly due to the warnings and cautions associated with button batteries and the key fobs themselves.
