Your Ford key fob is an indispensable tool for daily convenience, allowing you to remotely lock, unlock, and even start 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 simple yet essential skill for any car owner, saving you time and potential inconvenience. This guide will walk you through the process, ensuring you can quickly and easily restore your key fob’s functionality.
Step 1: Accessing the Key Blade and Opening the Fob
The first step is to locate and release the mechanical key blade housed within your Ford key fob. The method for releasing this blade varies slightly depending on your specific Ford model.
For some models, you’ll find a small release button, often located on the side or bottom of the key fob. Press and hold this button to manually slide out the key blade.
For other Ford key fobs, there might not be a visible button. In these cases, you’ll typically need to firmly grasp the key fob and manually pull or slide the key blade to extract it. Refer to your owner’s manual if you are unsure of the exact method for your key fob model.
Step 2: Prying Open the Key Fob Casing
Once the key blade is removed, you’ll use the created space to gently pry open the key fob casing. A small flathead screwdriver or even a coin will be helpful for this step.
Insert the tip of your flathead screwdriver or the edge of a coin into the slot where the key blade was just removed. This slot is usually along the seam of the key fob casing.
Apply gentle but firm pressure and twist the screwdriver or coin. You should feel the casing begin to separate. Work your way around the seam, gently prying until the two halves of the key fob casing come apart. Be careful not to apply excessive force, as this could damage the casing.
Inside, you will now see the battery compartment and the battery itself.
Step 3: Removing the Old Battery
With the key fob open, the next step is to remove the old battery. These batteries are typically small, round, and flat (button cell batteries).
You can again use your flathead screwdriver, or even your fingertip in some cases, to carefully pry the old battery out of its compartment. Often, there is a small clip or edge that holds the battery in place. Gently push or pry at the edge of the battery to dislodge it.
Take note of the battery’s orientation before removing it. Specifically, observe which side is facing upwards (usually marked with a “+” sign). This is crucial for installing the new battery correctly.
Step 4: Installing the New Battery
Now it’s time to install the new battery. Ensure you have the correct replacement battery for your Ford key fob. The battery type is usually printed on the old battery itself. Common types include CR2032, CR2025, or CR2016.
Place the new battery into the compartment, ensuring it is in the same orientation as the old battery. The positive (+) side of the battery should typically be facing upwards.
Press down gently on the new battery until it is securely seated in the compartment. You may hear a small click as it snaps into place.
Step 5: Reassembling the Key Fob
Finally, reassemble the key fob casing.
Carefully align the two halves of the key fob casing and press them firmly back together. You should hear or feel them snap securely into place.
Ensure there are no gaps and the casing is fully closed.
Slide the mechanical key blade back into its housing until it clicks or locks into its original position.
Test your key fob by pressing the lock, unlock, and other buttons to ensure it is functioning correctly. If the key fob still doesn’t work, double-check that the battery is installed correctly and is the right type.
Frequently Asked Questions
What type of battery does my Ford key fob need?
Ford key fobs typically use CR2032, CR2025, or CR2016 button cell batteries. The specific type required for your key fob will be printed on the original battery. Consult your owner’s manual for definitive information if needed.
What happens if I don’t replace my key fob battery?
If you don’t replace your key fob battery, it will eventually die completely. When this happens, you will lose the ability to remotely lock and unlock your vehicle using the fob. While most Ford vehicles have a physical key inside the fob for manual entry, relying solely on the physical key can be less convenient and reduce the security benefits of your key fob system.
Can I program my Ford’s personal entry keyless code myself?
Yes, you can program your personalized entry code. To do this, first enter the factory-set 5-digit code (refer to your owner’s manual if you don’t know it). Within five seconds, press the 1•2 button on the keypad, then enter your desired 5-digit personal code. Press the 1•2 button again to save the code. The doors should lock and unlock to confirm successful programming.
How often should I change my Ford key fob battery?
The lifespan of a Ford key fob battery can vary, but typically lasts for 2-3 years. Factors like frequency of use, temperature, and battery quality can affect battery life. If you notice your key fob range decreasing or becoming less responsive, it’s likely time to replace the battery.
Changing your Ford key fob battery is a straightforward task that you can easily accomplish at home. By following these simple steps, you can ensure your key fob remains functional and convenient for years to come.
