By following these steps, you can successfully replace the battery in your Kia Soul key fob, ensuring smooth operation and access to your vehicle.

What Steps Should You Follow to Open Your Kia Soul Key Fob?

To open your Kia Soul key fob, you should follow these steps: locate the small notch or seam, use a flat tool to gently pry open the fob, and carefully separate the two halves.

Locate the small notch or seam on the key fob
Use a flat tool (like a screwdriver) to pry open the fob
Gently separate the two halves of the fob
Replace the battery if needed

These steps provide a clear method to access the inner workings of your key fob; however, the condition of the key fob may vary, affecting ease of opening.

Locate the Small Notch or Seam: Locating the small notch or seam on the key fob is crucial for a successful opening. This notch is usually present on the side of the key fob. Identifying it allows you to minimize damage to the fob during the opening process.
Use a Flat Tool to Pry Open the Fob: Using a flat tool, such as a small flathead screwdriver or a coin, is necessary to aid in prying open the key fob. Insert the tool into the notch and gently twist. This action creates leverage, helping the fob to open without excessive force, which could cause it to break.
Gently Separate the Two Halves of the Fob: Once you have applied pressure to the notch, gently separate the two halves of the key fob. This separation should be done slowly to avoid snapping any internal components. Typically, the fob contains clips that hold the halves together, and careful manipulation will prevent them from breaking.
Replace the Battery if Needed: If your key fob is not working after opening, it might be due to a dead battery. Replace it with the correct type, often a CR2032 coin battery for Kia key fobs. Ensure the battery terminals align correctly to maintain proper function. After replacing the battery, reassemble the key fob by snapping the halves back together securely.
