Introduction

As a car owner, maintaining your vehicle is crucial. One often overlooked aspect is the key fob battery. In this guide, I’ll show you how to replace the key fob battery for the Mitsubishi Diamante models from 2000 to 2004.

This process is simple and requires minimal tools. By following these steps, you can save time and avoid the hassle of a dead key fob battery.

Tools and Materials Needed

Before starting, gather the necessary tools and materials:

• CR2032 coin battery
• Small Phillips head screwdriver

If you don’t have these tools, you can find them online. Precision screwdrivers and CR2032 batteries are readily available on platforms like Amazon.

Step-by-Step Guide

Step 1: Open the Key Fob

First, flip the key fob over. Locate the small screw on the back. Use your Phillips head screwdriver to remove it. Keep the screw safe as you’ll need it later.

Once the screw is out, the key fob will open easily. You can use your fingernails or a small tool to separate the two halves. If the key ring falls out, don’t worry. We’ll reattach it later.

Step 2: Remove the Old Battery

With the key fob open, you’ll see the old CR2032 battery. Use your screwdriver or another tool to gently pry the battery out. Dispose of the old battery properly.

Step 3: Insert the New Battery

Take your new CR2032 battery and insert it into the slot. Ensure the positive side (the side with the text) is facing down. Press it firmly to make sure it’s secure.

Step 4: Reassemble the Key Fob

Now, place the key ring back onto the post if it fell out. Align the two halves of the key fob and press them together. Finally, reinsert the screw and tighten it with your screwdriver.

Testing and Final Checks

Once you’ve reassembled the key fob, it’s time to test it. Try locking and unlocking your car to ensure the new battery works properly. If everything is functioning as expected, you’re good to go.

Common Issues and Troubleshooting

Sometimes, even after replacing the battery, the key fob may not work. Here are a few troubleshooting tips:

• Check the Battery Orientation: Make sure the battery is inserted with the positive side facing down.
• Inspect the Contacts: Ensure the battery contacts are clean and making good contact with the terminals.
