Introduction

Changing the battery in your Ford Focus remote key fob is a simple task. If your key fob looks like the one described here, this guide will walk you through the steps.

The process involves separating the key fob into two pieces to access the internal battery. This guide will explain how to do this safely and efficiently.

Tools Needed

To replace the battery, you will need:

• Flathead screwdriver
• Another key (optional)
• CR2032 battery

Step-by-Step Guide

Step 1: Identify the Key Fob

First, ensure your key fob matches the description. This guide applies to Ford Focus key fobs used from 2011 to the present.

Step 2: Locate the Notch

Look for a small notch in the upper right corner of the key fob. This is where you will insert your tool to separate the pieces.

Step 3: Insert the Tool

Use a flathead screwdriver or another key. Insert it into the notch and twist gently. This will create some separation between the two pieces of the key fob.

Step 4: Separate the Pieces

Work your way towards the middle of the key fob, where you might attach a keyring. Twist again to further separate the two pieces.

Step 5: Access the Battery

Once the pieces are separated, you will see the internal battery. The battery type is CR2032, a three-volt coin battery.

Step 6: Remove the Old Battery

Pop the old battery out. It should fall out easily. Be careful not to lose any small parts.

Step 7: Insert the New Battery

Place the new CR2032 battery into the slot. Ensure the positive side is facing you. There is a rubber backing that helps keep the battery in place. If it falls off, replace it in the same way.

Step 8: Reassemble the Key Fob

Snap the two pieces of the key fob back together. Make sure everything is tight and secure.

Tips and Tricks

Using a Key Instead of a Screwdriver

While a flathead screwdriver is recommended, another key can work just as well. It provides similar leverage and is often more readily available.

Ensuring Proper Battery Placement

Placing the battery with the correct side facing up is crucial. The positive side should face you. Incorrect placement can result in the key fob not working.

Common Issues

Difficulty Separating the Key Fob

If you have trouble separating the key fob, ensure you are inserting the tool into the correct notch. Twisting gently should create enough separation.

Battery Not Staying in Place

If the battery does not stay in place, check the rubber backing. It helps secure the battery. Ensure it is positioned correctly.

Conclusion

Replacing the battery in your Ford Focus key fob is a straightforward process. Following these steps will help you do it quickly and efficiently.

Always ensure you have the correct tools and battery type. A CR2032 battery is required for this key fob.
