Identifying the Battery Type for Your 2020 Ford Fusion Key Fob
First things first, you’ll need to know what type of battery your key fob uses. The 2020 Ford Fusion key fob battery type is a CR2450 battery. This is a common type of coin cell battery, readily available at most drugstores, supermarkets, and online retailers. Knowing the correct battery type beforehand will save you a trip back to the store.
Step-by-Step Guide to Replacing Your 2020 Ford Fusion Key Fob Battery
Replacing the battery in your 2020 Ford Fusion key fob is a simple process. Here’s how to do it:
-
Gather Your Tools: You’ll need a small flathead screwdriver or a similar tool to gently pry open the key fob. Also, have your new CR2450 battery ready.
-
Locate the Notch: Examine your Ford Fusion key fob. You’ll find a small notch, usually on the side or bottom of the fob. This is where you’ll insert your flathead screwdriver.
-
Carefully Open the Fob: Gently insert the flathead screwdriver into the notch and twist lightly. The key fob case should begin to separate. Work your way around the seam, carefully prying the two halves of the fob apart. Avoid using excessive force, as you could damage the plastic casing.
-
Remove the Old Battery: Once the key fob is open, you’ll see the battery. Take note of how the old battery is positioned (+ side up or down). You can usually use your fingertip or the edge of the screwdriver to gently lift the old battery out of its compartment.
-
Insert the New Battery: Take your new CR2450 battery and insert it into the battery compartment, ensuring the polarity (+ and -) is correct and matches the orientation of the battery you just removed.
-
Reassemble the Key Fob: Carefully snap the two halves of the key fob case back together. You should hear a click or feel them securely close. Ensure there are no gaps and the fob is properly sealed.
-
Test Your Key Fob: Try using your key fob to lock and unlock your 2020 Ford Fusion, and test the remote start and trunk release functions to ensure the new battery is working correctly.
What if a New Battery Doesn’t Solve the Problem?
In most cases, replacing the CR2450 battery will resolve issues with your 2020 Ford Fusion key fob. However, if you’ve replaced the battery and are still experiencing problems, there might be other factors at play.
-
Programming Issues: While a battery replacement itself usually doesn’t require reprogramming, if your key fob has been malfunctioning for a while, it might have lost synchronization with your vehicle. In this case, you may need to have your key fob reprogrammed by a Ford dealership or a qualified automotive locksmith.
-
Key Fob Damage: If your key fob has been dropped, gotten wet, or experienced other damage, internal components might be broken. In such cases, you might need to consider a 2020 Ford Fusion key fob replacement.
-
Vehicle Issues: In rare cases, issues with your vehicle’s receiver system could be the cause of key fob problems. If you suspect this, it’s best to consult with a Ford service center.
Where to Get a 2020 Ford Fusion Key Fob Replacement
If you determine that you need a complete 2020 Ford Fusion key fob replacement, you have a few options:
-
Ford Dealership: Your local Ford dealership can certainly provide a new key fob and program it for your vehicle. This is generally the most expensive option but ensures you get a genuine OEM (Original Equipment Manufacturer) part. Ford part numbers for this remote include 164-R8149, HS7Z-15K601-B.
-
Automotive Locksmith: A reputable automotive locksmith specializing in key fobs can often provide and program replacement fobs at a more competitive price than a dealership. They can also cut the emergency insert key if needed. Look for locksmiths who are familiar with Ford key systems.
-
Online Retailers: You can also purchase replacement 2020 Ford Fusion key fobs online.
