Experiencing a “Key Not Detected” message on your 2018 Ford F-150 can be frustrating, especially when your key fob battery is dying. Just like any battery, your key fob battery has a limited lifespan. Don’t get stranded or caught off guard. Replacing your Ford F-150 key fob battery is a straightforward process you can easily do yourself, saving time and money.
The good news is that you likely won’t need to visit a dealership for this simple task. For many 2018 Ford F-150 models, the key fob battery is a common CR2032 type. However, it’s always best to double-check your owner’s manual or open your key fob to confirm the exact battery type you need. Some models, particularly newer ones or specific trims, might use a CR2450 battery, as shown in some Ford owner manuals.
To replace the battery in your 2018 Ford F-150 key fob, follow these easy steps:
-
Locate the notch: Find the small notch on the side of your key fob. This is usually near the key ring attachment.
-
Open the fob: Use a small flathead screwdriver or a coin to gently pry open the fob at the notch. Twisting gently should separate the two halves of the fob.
-
Identify the battery: Once open, you’ll see the battery. Note the type of battery (likely CR2032 or CR2450) and its orientation (+ side up).
-
Remove the old battery: Carefully remove the old battery. You can use your fingertip or the small screwdriver if needed.
-
Insert new battery: Install the new CR2032 or CR2450 battery, ensuring the correct orientation (+ side up).
-
Close the fob: Snap the two halves of the key fob back together until they are securely closed.
-
Test your fob: Test the buttons on your key fob to ensure it’s working correctly and the “Key Not Detected” message is gone.
Replacing your 2018 Ford F-150 key fob battery is a quick and easy maintenance task. By taking a few minutes to do it yourself, you can avoid potential key fob issues and keep your truck running smoothly. Always remember to check your owner’s manual or the battery itself to confirm the correct battery type before replacement.
