How to Change Battery in Your 2019 Ford Fusion Key Fob

If your 2019 Ford Fusion key fob is acting up – locking and unlocking doors intermittently or requiring you to stand inches away from your car – it’s likely a sign that the battery is dying. Luckily, replacing the battery in your key fob is a quick and easy process you can do yourself, saving you a trip to the dealership.

This guide provides a step-by-step walkthrough on how to change the battery in your 2019 Ford Fusion key fob, empowering you to regain control of your car access with minimal hassle.

What You’ll Need to Change Your Ford Fusion Key Fob Battery

Before you get started, gather the following items:

A new CR2032 battery: This is the standard battery for most Ford key fobs. You can find them at most hardware, auto parts, and electronics stores.
A small flathead screwdriver or a plastic pry tool: This will help you separate the two halves of the key fob.

Step-by-Step Guide to Changing the Battery

Here’s a detailed guide to replacing the battery:

Locate the release button: On the back of your key fob, you’ll see a small, round button. This is the key blade release button.
Remove the key blade: Press and hold the release button while gently sliding the key blade out of the fob.
Separate the key fob halves: Using your flathead screwdriver or pry tool, carefully insert it into the seam where the key blade was removed. Gently pry the two halves of the fob apart. You may hear a slight click as the halves separate.
Identify the battery: Inside the fob, you’ll see the CR2032 battery nestled in a compartment.
Remove the old battery: Gently pry out the old battery. Avoid touching the positive (+) side of the battery, which is usually facing up.
Insert the new battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side faces up.
Reassemble the key fob: Align the two halves of the key fob and press them together until you hear a click, indicating they’re securely closed.
Reinsert the key blade: Slide the key blade back into its slot on the fob until it clicks into place.
Test the key fob: Ensure the battery change was successful by testing the lock, unlock, and panic buttons.

Troubleshooting: What if My Key Fob Still Doesn’t Work?

If your key fob still doesn’t function correctly after changing the battery, here are a few things to check:

Battery orientation: Double-check that the new battery is inserted correctly with the positive (+) side facing up.
Proper reassembly: Ensure that the key fob halves are completely snapped back together.
Key fob programming: In rare cases, you may need to reprogram your key fob to your vehicle. Refer to your Ford Fusion owner’s manual for instructions on how to do this.
