How to Open a Mitsubishi Key Fob and Easily Replace the Battery Yourself

To open your Mitsubishi key fob for battery replacement, follow these steps: 1. Find the seam between the two halves of the fob. 2. Use a flathead screwdriver to gently twist and open it. 3. Take out the old battery. 4. Insert a new battery in the same location. 5. Snap the fob closed again.

Next, remove the old battery. Most Mitsubishi key fobs use a CR2032 battery, which is about the size of a coin. Slide the battery out from its compartment and dispose of it safely. Then, insert a new CR2032 battery, ensuring the positive (+) side faces up. Ensure it sits firmly in place.

After replacing the battery, carefully align the two halves of the fob and press them back together until they click. Test the functionality by pressing the buttons. If it works, you have successfully opened your Mitsubishi key fob and replaced the battery.

In the next part, we will discuss troubleshooting common issues with your Mitsubishi key fob after a battery replacement. This will help ensure it functions correctly after your DIY repair.

How Can You Identify Your Mitsubishi Key Fob Model Before Battery Replacement?

To identify your Mitsubishi key fob model before battery replacement, check the fob’s part number, inspect the physical design, and refer to your vehicle’s owner’s manual.

  1. Part Number: Locate the part number on the back of the key fob. The part number usually starts with a letter followed by a series of numbers (e.g., MB123456). This number identifies the specific model and ensures you purchase the correct replacement battery.

  2. Physical Design: Examine the key fob’s shape, button layout, and size. Different Mitsubishi models may have distinct key fob designs. For instance, a fob for a Mitsubishi Outlander may differ from that of a Mitsubishi Eclipse. Comparing your fob to images of known models online can help confirm the model.

  3. Owner’s Manual: Consult your vehicle’s owner’s manual for information about the key fob. The manual may provide details on the key fob model and the battery type it requires. If the manual is not available, check Mitsubishi’s official website for online resources specific to your car model.

These identification methods are effective and ensure correct battery replacement, leading to improved functionality of your Mitsubishi key fob.

What Tools Are Essential for Opening a Mitsubishi Key Fob Safely?

To open a Mitsubishi key fob safely, essential tools include a flathead screwdriver, a small pair of pliers, and a new battery.

  1. Flathead screwdriver
  2. Small pliers
  3. New battery (typically CR2032 or CR2025)

These tools help in disassembling the key fob without causing damage. Using the right tools ensures a safer process and minimizes the risk of breaking the fob.

  1. Flathead screwdriver:
    A flathead screwdriver is essential for gently prying open the key fob casing. When using a flathead screwdriver, position it in the seam of the fob and twist carefully to avoid damaging the plastic. This tool allows access to replace the battery inside.

  2. Small pliers:
    Small pliers can assist in removing the old battery from its compartment. Their grip enables a secure hold, making it easier to pull the battery out without slipping. This tool is particularly useful if the battery is seated tightly inside the fob.

  3. New battery:
    A new battery, often CR2032 or CR2025, is crucial for replacing the old one. These lithium batteries provide the necessary power for your key fob to function correctly. It’s important to check the specifications of your key fob model to ensure compatibility with the new battery.

Using these tools correctly will make opening your Mitsubishi key fob a straightforward task.

How Do You Open a Mitsubishi Key Fob Without Damaging It?

To open a Mitsubishi key fob without damaging it, follow these steps carefully using a suitable tool to avoid breaks or scratches.

First, identify the seam on the fob where the two halves meet. Carefully insert a small flathead screwdriver or a similar tool into this seam. Apply gentle pressure to pry it open slowly. Ensuring that you work your way around the fob gradually will help maintain the integrity of the casing. Here are detailed steps:

  • Find the seam: Look around the edges of the key fob. The seam is typically thin and might be slightly raised.
  • Choose the right tool: A small flathead screwdriver works well. Alternatively, a plastic prying tool can help avoid scratching the plastic surface.
  • Pry gently: Insert the tool at one end of the seam and push down softly. Move the tool along the seam while maintaining a gentle pressure. This helps in loosening the clips without breaking them.
  • Open the fob: Once you’ve loosened the clips along the seam, you can gently pull the two halves apart. Take care not to force them apart too quickly, as this can lead to cracks.
  • Replace the battery: If your goal is to replace the battery, locate the battery holder after opening the fob. Carefully remove the old battery and insert the new one, ensuring it is in the correct orientation.

Following these steps allows you to open your Mitsubishi key fob effectively while minimizing the risk of damage.

How Can You Ensure Proper Installation of a New Battery in Your Mitsubishi Key Fob?

To ensure proper installation of a new battery in your Mitsubishi key fob, follow these steps: use the right battery type, open the fob carefully, replace the old battery with the new one, and test the fob to confirm functionality.

First, identify the correct battery type for your Mitsubishi key fob. Most Mitsubishi key fobs utilize a CR2032 coin cell battery. Refer to your vehicle’s manual to confirm the battery specification.

Next, open the key fob without damaging it. Use a flat, thin object like a screwdriver to gently pry apart the two halves of the fob. Be cautious to avoid cracking the plastic casing.

Then, replace the old battery with the new one. Observe the orientation of the battery during removal. The positive side, marked with a “+” sign, should face upwards when inserting the new battery.

Finally, test the key fob to ensure it works. Press the buttons to confirm that they respond correctly. If the fob does not function, recheck the battery installation for errors or ensure the battery is not depleted.

By following these steps, you can successfully install a new battery in your Mitsubishi key fob and maintain its functionality.

How Do You Test the New Battery in Your Mitsubishi Key Fob to Confirm Functionality?
