Your Ford key fob is an incredibly convenient tool, allowing you to remotely lock, unlock, and even start your vehicle. However, like any battery-powered device, the key fob’s battery will eventually need replacing. Knowing how to change your Ford key fob battery is a valuable skill that can save you time and potentially money. This guide will walk you through the simple steps to replace your Ford key fob battery and get you back to conveniently accessing your vehicle.
Step-by-Step Guide to Changing Your Ford Key Fob Battery
Changing the battery in your Ford key fob is a straightforward process that you can typically accomplish in just a few minutes with minimal tools. Here’s a step-by-step guide to help you through it:
Step 1: Locate the Key Blade Release
The first step is to access the mechanical key blade that is housed within your Ford key fob. The method for releasing this blade can vary slightly depending on your specific Ford model and key fob type.
For many Ford key fobs, you’ll find a small release button. This button is usually located on the fob itself, often on the side or near the keyring attachment. Press and hold this button to manually release and slide out the metal key blade.
In some other Ford models, there might not be a dedicated release button. Instead, you may need to manually extract the key blade by firmly pulling or sliding it out. Refer to your owner’s manual if you are unsure how to release the key blade for your specific key fob.
Step 2: Open the Key Fob Casing
Once the key blade is removed, you’ll need to open the key fob casing to access the battery compartment. A flathead screwdriver is typically the only tool required for this step.
Locate the small slot or seam on the side of the key fob where the key blade was originally housed. This is where you will insert the flathead screwdriver. Gently insert the tip of the screwdriver into this slot.
Carefully twist the screwdriver to pry the key fob open. Apply gentle pressure; you should feel the casing begin to separate. For key fobs where you manually extracted the blade, you can also use a thin coin, like a penny or nickel, to wedge into the gap near where the key blade was and twist to pop the cover off.
Step 3: Remove the Old Battery
With the key fob casing open, you will now see the battery. Ford key fobs commonly use a small, circular coin cell battery, often a CR2032 or similar type.
Use the flathead screwdriver again to carefully pry the old battery out of its compartment. Batteries can sometimes be a snug fit, so gentle leverage with the screwdriver will help to dislodge it. Be careful not to damage the battery compartment or any of the surrounding components.
Step 4: Install the New Battery
Take your replacement battery – ensure you have the correct type (check the old battery for the model number if you are unsure). Install the new battery into the compartment, making sure the polarity is correct.
Typically, the positive (+) side of the battery should be facing upwards. There is usually a small “+” symbol in the battery compartment to guide you. Placing the battery in the wrong way may prevent the key fob from working.
Step 5: Reassemble the Key Fob
Carefully snap the two halves of the key fob casing back together. Ensure they are firmly closed and that there are no gaps. You should hear a click as the casing pieces securely join.
Step 6: Test Your Key Fob
Finally, test your key fob to ensure the new battery is working correctly. Press the lock and unlock buttons to confirm they are functioning as expected. If your Ford has remote start, test that function as well. If everything works, you have successfully changed your Ford key fob battery!
Troubleshooting and Tips
- Key Fob Still Not Working? If your key fob doesn’t work after replacing the battery, double-check that you installed the battery with the correct polarity (+ side up). Also, ensure the battery model is correct for your key fob. If it still doesn’t work, there might be another issue, and you may need to consult your Ford dealer or a professional locksmith.
- Battery Type: Common Ford key fob batteries are CR2032, CR2025, or CR2450. Check your owner’s manual or the old battery for the correct type. You can purchase these batteries at most drugstores, supermarkets, and online retailers.
- Emergency Key: Remember that most Ford vehicles also come with a physical emergency key blade housed in the fob. If your key fob battery dies completely before you replace it, you can use this physical key to manually unlock your car door.
Frequently Asked Questions
How can I program my Ford’s personal entry keyless code?
To create your personalized entry code, you’ll first want to input the factory-set five-digit code (usually found in your owner’s manual or on a card that came with your vehicle). Next, within five seconds, press the 1•2 button on the keypad, then enter the five-digit personal code you want to use. Ensure each number is inputted within five seconds of the last. Then, press the 1•2 button again to save the personalized code as position one. The car doors should lock and unlock to confirm successful programming.
What happens if I don’t replace my key fob’s 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. While you can use the physical emergency key to enter your car, relying solely on the physical key can be less secure and less convenient than using the key fob.
Changing your Ford key fob battery is a simple maintenance task that any Ford owner can do. By following these steps, you can ensure your key fob remains functional and convenient for years to come.
