Introduction

Replacing the battery in your Mitsubishi Lancer key fob is a straightforward process. This guide will walk you through each step, ensuring your key fob is back to working condition in no time.

Whether you have the version with the panic button or the trunk button, the process and the battery required are the same. Let’s dive into the details.

Tools and Materials Required

Before starting, gather the necessary tools and materials. Here’s what you’ll need:

• CR2032 battery
• Small Phillips head screwdriver

If you don’t have a CR2032 battery, you can easily find one on Amazon.

Step-by-Step Battery Replacement

Step 1: Remove the Screw

First, locate the small screw on the back of your key fob. Use your Phillips head screwdriver to remove it. Set the screw aside carefully.

Step 2: Open the Key Fob

After removing the screw, gently pull apart the two halves of the key fob. Be cautious as the keyring might fall out. Don’t worry; we’ll reassemble everything later.

Step 3: Remove the Old Battery

Once open, you will see the battery. Gently knock it out of its compartment. Sometimes, a small metal piece may also come loose. This is normal and will be reassembled shortly.

Step 4: Insert the New Battery

Take your new CR2032 battery. Ensure the positive side (marked with a plus sign) is facing down. Before placing the battery, slide the small metal piece back into its position at the bottom of the compartment. Hold it in place and insert the new battery.

Step 5: Reassemble the Key Fob

With the new battery in place, align the keyring post and reattach the keyring if it fell out earlier. Snap the two halves of the key fob back together.

Step 6: Secure the Screw

Finally, reinsert the screw you set aside earlier and tighten it with your Phillips head screwdriver. Your key fob should now be fully functional.

Common Issues and Troubleshooting

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

• Ensure the battery is inserted correctly.
• Check for any loose components inside the key fob.
