Experiencing a “Key Not Detected” message on your Ford F-150 dashboard can be frustrating, especially when your key fob is right in your pocket. This was the exact situation I encountered recently with my 2023 Ford F-150 Lightning XLT ER. Just like with my wife’s car last year, this message served as a crucial warning sign: the key fob battery was likely nearing its end. Thinking back to that previous experience, I knew it was time to act fast before the fob stopped working altogether.
One might expect the Ford F-150 key fob to use the common CR2032 battery, similar to many garage door remotes. However, this is not the case. The Ford F-150 key fob, including the Lightning model, requires a CR2450 battery. This detail is clearly outlined in the owner’s manual, as shown in these screenshots:
To change the battery in your Ford F-150 key fob, you will need a CR2450 battery and a small flathead screwdriver or similar tool to open the fob. Here’s a step-by-step guide based on the owner’s manual and general key fob battery replacement procedures:
-
Locate the notch: On the side of your Ford F-150 key fob, you’ll find a small notch. This is the access point to open the fob and access the battery compartment.
-
Open the key fob: Insert the tip of your flathead screwdriver or tool into the notch. Gently twist or pry to separate the two halves of the key fob. Be careful not to apply excessive force to avoid damaging the casing.
-
Identify the battery: Once open, you’ll see the CR2450 battery. Take note of the battery’s orientation (+ side up or down) before removing it. This will ensure you install the new battery correctly.
-
Remove the old battery: Carefully remove the old CR2450 battery. You may be able to use your fingertip or the flathead screwdriver to gently pry it out.
-
Insert the new battery: Install the new CR2450 battery, ensuring it’s placed in the correct orientation as you noted in step 3. Push it gently until it is securely in place.
-
Close the key fob: Align the two halves of the key fob and press them firmly back together until they snap closed. Ensure there are no gaps and the fob is securely sealed.
-
Test the key fob: Test the key fob functions to ensure the new battery is working correctly. You should no longer see the “Key Not Detected” message on your dashboard.
By following these simple steps, you can easily replace the battery in your Ford F-150 key fob and avoid being stranded with a non-functional remote. Remember to use the correct CR2450 battery type for optimal performance. Hopefully, this guide will serve as a helpful reference for Ford F-150 owners needing to perform this simple maintenance task.
