Just like any electronic device, your Ford key fob, the handy remote that controls access to your vehicle, relies on batteries to function. Over time, these batteries will deplete, potentially leaving you locked out or unable to remotely start your car. Fortunately, replacing the battery in your Ford key fob is a straightforward task you can easily accomplish at home. This guide will walk you through the process of how to Open A Ford Key Fob and replace its battery, ensuring your remote remains functional and reliable.
Knowing when to replace your Ford key fob battery is crucial. Ford vehicles are often equipped with a warning system that displays a message on your instrument cluster or information screen indicating a low key fob battery. If you see this warning, or if you notice your key fob is becoming less responsive, it’s time for a battery change. Don’t wait until your key fob completely fails; addressing the issue proactively can save you from potential inconvenience.
Tools You’ll Need to Open Your Ford Key Fob
Before you begin, gather the necessary tools. Luckily, you likely already have everything you need right at home:
- Small Flathead Screwdriver: This will be used to gently pry open the key fob casing. For some Ford key fob models, a small coin can also work.
- New Battery: Refer to your owner’s manual to identify the correct type of replacement battery for your specific Ford key fob. Common types include CR2032 or CR2025 button cell batteries.
- Soft Cloth (Optional): To protect the key fob casing from scratches during the opening process.
Step-by-Step Guide to Open and Replace Your Ford Key Fob Battery
Follow these simple steps to safely open a ford key fob and replace its battery:
-
Release the Key Blade: Locate the key blade release mechanism on your Ford key fob. This may be a small button you need to press or a lever you need to slide. Once activated, the mechanical key blade should slide out of the fob. Set the key blade aside.
-
Open the Key Fob Casing: With the key blade removed, you’ll see a small slot or seam along the edge of the key fob casing. This is where you will insert your flathead screwdriver or coin.
-
Using a Screwdriver: Carefully insert the tip of the flathead screwdriver into the slot and gently twist. Apply slight pressure to pry the two halves of the key fob casing apart. Work your way around the seam, gently prying until the casing separates.
-
Using a Coin: If your Ford key fob model is designed for coin opening (often found on models where the blade pulls straight out), insert the edge of a small coin into the slot where the key blade was housed. Twist the coin to separate the casing.
Take your time and avoid using excessive force, as you could damage the key fob casing. A soft cloth placed between the screwdriver/coin and the plastic can help prevent scratches.

-
Battery Replacement: Once the key fob casing is open, you will see the battery. Note the orientation of the battery (usually positive side up, marked with a “+” sign). Use the flathead screwdriver to gently pry the old battery out of its compartment. Insert the new battery, ensuring it is placed in the same orientation as the old one.
