Your Ford key fob is a convenient tool for locking, unlocking, and sometimes even starting your vehicle remotely. However, these fobs are powered by batteries, and like any battery, they will eventually need to be replaced. Knowing how to change the battery in your Ford key fob is a simple yet essential skill for any car owner, saving you time and potential frustration. This guide will walk you through the process step-by-step.
Step 1: Identify Your Key Fob Type and Prepare
Ford key fobs come in various designs, but the battery replacement process is generally similar across models. The first step is to identify the type of key fob you have and gather the necessary tools. You will typically need:
- A new battery: Most Ford key fobs use a CR2032 or CR2025 button cell battery. Check your owner’s manual or the old battery for the exact type. Having the correct battery type is crucial for proper function.
- A small flathead screwdriver or a coin: This will be used to gently pry open the key fob casing. Using the right tool will prevent damage to the fob.

Step 2: Open the Key Fob Casing
The method to open your Ford key fob depends on its design. Here are common approaches:
- Release Button/Lever: Some fobs have a small release button or lever, often located on the side or bottom of the fob. Pressing this button usually allows you to remove a physical key blade or directly access the battery compartment.
- Manual Key Blade Removal: If there’s no release button, you might need to manually remove the physical key blade. Look for a small latch or point where you can slide or pull the key blade out. Once removed, this may reveal a slot or opening to pry the fob open.
- Prying Open with a Screwdriver or Coin: For fobs that split into two halves, locate the seam running around the edge of the fob. Insert the tip of your flathead screwdriver or a coin into this seam, usually near where the key blade was (or is). Gently twist the screwdriver or coin to pry the two halves of the fob casing apart. Work your way around the seam carefully to avoid cracking the plastic.

Step 3: Remove the Old Battery
Once the key fob is open, you’ll see the battery. Note the orientation of the battery, specifically which side is facing up (usually the positive “+” side). This is important for installing the new battery correctly.
- Gently Pry Out the Battery: Use your flathead screwdriver or coin to gently pry the old battery out of its compartment. Be careful not to damage the battery contacts. You might be able to use your fingertip if there is enough space to get a grip.
Step 4: Install the New Battery
Now it’s time to install the new battery.
- Insert the New Battery: Place the new battery into the compartment, ensuring it is in the same orientation as the old one (positive “+” side up). Push down firmly until the battery is securely in place.
Step 5: Reassemble the Key Fob
With the new battery installed, carefully reassemble the key fob casing.
- Snap the Casing Back Together: Align the two halves of the fob casing and press them firmly together until they snap back into place. Ensure there are no gaps and the fob is securely closed.
- Reinsert Key Blade (if removed): If you removed the physical key blade, slide it back into its slot until it clicks or locks into position.
Step 6: Test Your Key Fob
Finally, test your key fob to ensure the battery replacement was successful.
- Test Lock/Unlock and Other Functions: Press the lock, unlock, and any other buttons on your key fob to verify they are working correctly. If your Ford has remote start, test that function as well.
If the key fob is still not working, double-check the battery orientation and that you have used the correct battery type. If problems persist, you may need to consult your Ford owner’s manual or contact a Ford dealership for assistance.
