What You Need

Step-by-Step Guide

Let’s dive into the process of replacing your key fob battery.

1. Identify the Key Fob Type

First, ensure you have the correct key fob. The 2010-2014 Ford Mustang uses a rounded smart key. Confirm this before proceeding.

2. Locate the Split Line

Examine the key fob closely. You will notice a line running around the middle, indicating where the key fob splits apart.

3. Score the Edges

Using a razor blade, carefully score the edges of the key fob. This helps in separating the two halves. Take your time to avoid damaging the fob.

4. Create Separation

Once scored, use a small flathead screwdriver to gently pry the two halves apart. Start at the top where you would attach a key ring. This spot usually offers the best leverage.

5. Open the Key Fob

Continue working your way around the key fob, gently prying it open. Be patient and avoid forcing it. The key fob will eventually pop open.

6. Remove the Battery Cover

With the key fob open, you will see a small battery cover. Remove this cover to access the battery compartment.

7. Replace the Battery

Remove the old CR2032 battery. Note the orientation of the positive side, which should be facing up. Insert the new battery with the positive side up.

8. Reassemble the Key Fob

Replace the battery cover and ensure it is securely in place. Align the two halves of the key fob and press them together until they snap shut.

Testing the Key Fob

After replacing the battery, test your key fob. Ensure all functions work correctly. If not, recheck the battery orientation and the assembly.

Common Issues and Solutions

Sometimes, you may encounter issues even after replacing the battery. Here are some common problems and their solutions.

Key Fob Not Working

If the key fob does not work, ensure the battery is installed correctly. Check the orientation and make sure the battery is seated properly.

Key Fob Falls Apart

If the key fob does not snap together securely, ensure all internal components are correctly aligned. Misalignment can prevent proper closure.

Battery Drains Quickly

If the new battery drains quickly, there may be an issue with the key fob itself. Consider consulting a professional for further diagnosis.

Maintaining Your Key Fob

Regular maintenance can extend the life of your key fob. Here are some tips to keep it in good condition.
