Your Ford key fob is an essential tool, allowing you to remotely lock, unlock, and even start your vehicle. It’s powered by a battery, and like any battery, it will eventually need replacing. Knowing how to change the battery in your Ford key fob is a simple yet valuable skill that can save you time and hassle. This guide will walk you through the process step-by-step, ensuring you can easily replace your key fob battery and get back on the road.
Tools You’ll Need
Before you begin, gather these simple tools:
- A new battery (check your owner’s manual or the old battery for the correct type – typically a CR2032 or CR2025 button cell battery)
- A small flat-head screwdriver or a coin
- A soft cloth or paper towel (optional, to protect the key fob casing)
Step-by-Step Guide to Changing Your Ford Key Fob Battery
Follow these steps to replace the battery in your Ford key fob:
Step 1: Access the Key Blade
The first step is to access the mechanical key blade housed within your Ford key fob. The method for releasing the key blade varies slightly depending on your Ford model.
-
For models with a release button: Look for a small button, often located near the keyring loop or on the side of the key fob. Press and hold this button while gently pulling the key blade away from the fob.
-
For models without a release button: You may need to manually slide or pull the key blade to remove it. Examine the key fob closely for any small levers or areas that look like they might allow the blade to be released.

Step 2: Open the Key Fob Casing
Once the key blade is removed, you need to open the key fob casing to access the battery compartment.
-
Using a screwdriver: Locate the small slot or seam on the side of the key fob where the key blade was positioned. Insert the tip of your flat-head screwdriver into this slot. Gently twist the screwdriver to pry the key fob casing open. If you’re concerned about scratching the plastic, wrap the tip of the screwdriver with a soft cloth.
-
Using a coin: If you don’t have a screwdriver handy, a coin can also work. Insert the edge of a coin into the slot and twist gently to separate the two halves of the key fob.

Step 3: Remove the Old Battery
With the key fob casing open, you’ll see the battery. Note the orientation of the battery (positive side up or down) before removing it.
- Prying out the battery: Use the flat-head screwdriver or your fingertip to gently pry the old battery out of its housing. Be careful not to damage the battery contacts.

Step 4: Install the New Battery
Now, it’s time to install the new battery.
- Inserting the new battery: Place the new battery into the battery compartment, ensuring it’s in the same orientation as the old battery (usually positive side facing up, marked with a “+” symbol). Push down gently until the battery is securely in place.
Step 5: Reassemble the Key Fob
Once the new battery is installed, carefully reassemble the key fob casing.
- Snapping the casing back together: Align the two halves of the key fob casing and press them firmly together until they snap back into place. Ensure there are no gaps and the casing is securely closed.
Step 6: Test Your Key Fob
Finally, test your Ford key fob to ensure the new battery is working correctly.
- Testing remote functions: Press the lock, unlock, and any other buttons on your key fob to verify they are functioning as expected. Your car should respond to the key fob commands.

Press the 1•2 button again to save the personalized code. The car doors will lock and unlock to confirm successful programming.
