Your Ford key fob is a convenient tool that allows for keyless entry and remote operation of your vehicle. Powered by a small battery, this device will eventually require a battery replacement to ensure seamless functionality. Knowing how to replace the battery in your Ford key fob is a simple yet essential skill for every Ford owner, preventing you from being locked out and maintaining the convenience you’re accustomed to. This guide will walk you through the process step-by-step, making it an easy DIY task.
Step 1: Accessing the Key Blade
The first step in replacing your Ford key fob battery involves exposing the key blade. Depending on your Ford model, this process can vary slightly. Some models require manual extraction of the blade, while others are equipped with a dedicated release button.

For models with a release button, locate and press it to detach the key blade. If your key fob requires manual extraction, simply grasp the blade firmly and pull it away from the fob casing. Set the key blade aside in a safe place as you proceed with the battery replacement.
Step 2: Opening the Key Fob Casing
With the key blade detached, the next step is to open the key fob casing to access the battery compartment. For this, you will need a small flat-head screwdriver or a coin.

Locate the small slot or seam on the side of the key fob where the key blade was originally housed. Insert the flat-head screwdriver or the edge of a coin into this slot. Gently twist or pry to separate the two halves of the key fob casing. Take your time and apply steady pressure to avoid damaging the plastic casing. Once you hear a click or feel the casing begin to separate, carefully pull the two halves apart to reveal the battery inside.
Step 3: Removing the Old Battery
Now that the key fob is open, you will see the battery. Note its orientation before removal, specifically which side is facing up (+ or -). This will be important when installing the new battery.

Using the tip of your flat-head screwdriver, or your fingernail if possible, gently pry the old battery out of its compartment. Batteries can sometimes be held snugly in place, so apply gentle but firm pressure. Be careful not to damage the surrounding components within the key fob during battery removal. Once loose, remove the old battery and set it aside for proper disposal.
Step 4: Installing the New Battery
With the old battery removed, it’s time to install the new one. Ensure you have the correct replacement battery type for your Ford key fob. This information is usually found in your vehicle’s owner’s manual or by checking the markings on the old battery itself. Common types include CR2032, CR2025, or CR2016 batteries.

Place the new battery into the battery compartment, ensuring it is oriented in the same direction as the old battery. The positive (+) side of the battery should typically face upwards. Press down gently until the battery is securely seated in its place.
Step 5: Reassembling the Key Fob
After installing the new battery, carefully align the two halves of the key fob casing. Press them firmly together until they snap back into place. Ensure there are no gaps and that the casing is securely closed.
Step 6: Testing the Key Fob
Finally, test your Ford key fob to ensure the battery replacement was successful. Press the lock and unlock buttons to verify that your vehicle responds as expected. If the key fob functions correctly, you have successfully replaced the battery. If not, re-open the fob and double-check the battery orientation and that the battery is correctly seated. If issues persist, consider consulting your Ford dealership or a professional locksmith.
Frequently Asked Questions
How can I program my Ford’s personal entry keyless code?
To create your personalized entry code, you will first need to input the factory-set five-digit code. This code is usually found on a card in your owner’s manual. Once you have the factory code, enter it into the keypad. Within five seconds of entering the factory code, press the 1•2 button on the keypad, then immediately enter your desired five-digit personal code. Make sure to input each number within five seconds of the previous one. To save your personalized code, press the 1•2 button again. The car doors should lock and unlock to confirm that the new entry code has been successfully programmed.
What happens if I don’t replace my key fob’s battery?
If you neglect to replace your key fob battery, it will eventually die completely. Once this happens, you will lose the ability to remotely lock and unlock your vehicle. While many Ford models include a physical emergency key within the fob to manually unlock the door, relying solely on a physical key increases the risk of theft if the key is lost or stolen. Key fobs offer enhanced security and convenience, making timely battery replacement a worthwhile maintenance task.
Key fobs provide a significant advantage over traditional keys due to their reprogrammability and enhanced security features. Replacing a key fob is generally easier and more cost-effective than replacing traditional locks in case of loss or theft. While standard batteries provide ample power for key fobs for extended periods, Ford continues to innovate, exploring battery-free key fob technology powered by magnetic fields to further enhance convenience and reliability. Replacing the battery in your Ford key fob is a simple piece of vehicle maintenance that keeps you in control and on the road.
