Locating the Battery Compartment

The first step in changing your Kia Optima key fob battery is to locate the battery compartment. Most Kia Optima key fobs have a small release button or slot on the back. This might be a small indentation or a switch. Pressing this button or inserting a small flathead screwdriver will separate the key fob into two halves, revealing the battery. For some models, the battery compartment may be accessed by removing the valet key.

Identifying the Correct Battery

Once you’ve opened the key fob, you’ll need to identify the type of battery it uses. Most Kia Optima key fobs use a CR2032 3V lithium battery. These are readily available at most stores that sell batteries. It’s crucial to use the correct type of battery to avoid damaging the key fob. Using the incorrect battery can cause voltage inconsistencies and may not power the key fob.
