Your Ford key fob is a convenient tool that allows you to remotely access and secure your vehicle. Like any battery-powered device, the key fob battery will eventually need replacing. Knowing how to change your Ford key fob battery is a valuable skill that can save you time and hassle. This guide provides a straightforward, step-by-step approach to replacing your Ford key fob battery, ensuring you can maintain seamless access to your vehicle.
Step-by-Step Guide to Ford Key Fob Battery Replacement
Changing the battery in your Ford key fob is a relatively simple process that most owners can do themselves. Follow these steps to ensure a smooth and successful battery replacement.
Step One: Accessing 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.
- Manual Release: Some Ford key fobs require you to manually slide or pull a small latch or release button to extract the key blade.
- Release Button: Other models feature a dedicated release button that, when pressed, allows you to pull out the key blade.
Refer to your Ford owner’s manual if you’re unsure how to release the key blade for your specific model.
Step Two: Opening the Key Fob Casing
Once the key blade is removed, you can proceed to open the key fob casing to access the battery compartment.
- Locate the Seam: Examine the key fob casing to find the seam where the two halves of the fob meet. This seam is usually located where the key blade was housed.
- Prying the Casing:
- Screwdriver Method: Insert a small flat-head screwdriver into the seam. Gently twist the screwdriver to carefully pry the key fob casing open. Work your way around the seam, applying gentle pressure until the casing begins to separate.
- Coin Method: Alternatively, you can use a coin, such as a penny or nickel, to wedge into the seam near where the key blade was located. Twist the coin gently to pop the cover off.
Be careful not to apply excessive force, as this could damage the key fob casing. Once you’ve separated the halves, you’ll see the battery inside.
Step Three: Removing the Old Battery
With the key fob casing open, you can now remove the old battery.
- Battery Location: The battery is typically located in a small compartment within the key fob.
- Prying out the Battery: Use the flat-head screwdriver again to gently pry the battery out of its compartment. Batteries can sometimes be held in place snugly, so take your time and apply steady, gentle pressure.
Take note of the battery type and the orientation (positive side up or down) before removing it. This will ensure you install the new battery correctly. Most Ford key fobs use a CR2032 battery, but it’s always best to double-check the old battery before discarding it.
Step Four: Inserting the New Battery
Now it’s time to install the new battery into your Ford key fob.
- Battery Type: Ensure you have the correct replacement battery. As mentioned, CR2032 is a common type, but verify the type before purchasing.
- Orientation: Place the new battery into the compartment in the same orientation as the old one. Typically, the positive (+) side of the battery should be facing upwards. There may be markings in the battery compartment to indicate the correct orientation.
- Secure the Battery: Gently press the new battery into place until it is securely seated in the compartment.
Step Five: Reassembling the Key Fob
The final step is to reassemble the key fob casing.
- Align the Casings: Carefully align the two halves of the key fob casing.
- Press Together: Press the two halves firmly together until they snap securely back into place. Ensure there are no gaps between the casings.
- Reinsert Key Blade: Slide the mechanical key blade back into its housing until it clicks into the locked position.
