Is your Ford key fob suddenly not working? Before you panic, the most likely culprit is a dead battery. The key fob, essential for remotely locking, unlocking, and starting your Ford vehicle, relies on battery power. Fortunately, replacing a Ford key fob battery is a simple task you can easily do yourself at home. This guide will provide you with a step-by-step process to change your Ford key fob battery, saving you time and money compared to visiting a dealership.
Step-by-Step Guide to Replacing Your Ford Key Fob Battery
Changing the battery in your Ford key fob is straightforward and generally requires no special tools. Follow these simple steps to get your key fob working again:
Step 1: Open the Key Fob – Accessing the Emergency Key Blade
The first step is to access the emergency key blade housed within your Ford key fob. The method to release this blade varies slightly depending on your specific Ford model and key fob type.
- For some models: You may find a small release button or latch on the key fob. Press and hold this button, and the emergency key blade should slide out.
- For other models: There might not be a button. In this case, look for a small indentation or seam near where the key blade is housed. You may need to manually pry the key blade compartment open slightly to release the blade.

Step 2: Prying Open the Key Fob Casing
Once the emergency key blade is removed, you’ll need to carefully open the key fob casing to access the battery.
- Locate the Seam: Examine the key fob where the key blade was just removed. You’ll notice a seam running along the edge of the fob. This is where you’ll pry it open.
- Use a Flat Tool: Insert a thin, flat-head screwdriver or a coin into the seam. Gently twist the screwdriver or coin. You should feel the casing begin to separate.
- Avoid Excessive Force: Be gentle and patient. Applying too much force could damage the key fob casing. Work your way around the seam, gently prying until the casing splits open, revealing the battery compartment.

Step 3: Removing the Old Battery
With the key fob casing open, you’ll now see the battery. Ford key fobs typically use a small, round, flat battery, often a CR2032 type.
- Observe Battery Orientation: Before removing the old battery, take note of its orientation – specifically, which side is facing up (usually the positive (+) side). This is crucial for inserting the new battery correctly.
- Pry out the Battery: You can use the flat-head screwdriver again, or your fingernail, to gently pry the old battery out of its compartment. There might be a small lip or notch to help you get under the battery edge.

Step 4: Inserting the New Battery
Now it’s time to install the new battery.
- Correct Battery Type: Ensure you have the correct replacement battery. Check the old battery for the type (e.g., CR2032) and purchase the same type. These batteries are widely available at drugstores, supermarkets, and online retailers.
- Proper Orientation: Place the new battery into the compartment, ensuring the positive (+) side is facing upwards, matching the orientation of the old battery you noted in Step 3. If inserted incorrectly, the key fob will not function.
- Secure the Casing: Carefully snap the two halves of the key fob casing back together until they are firmly closed. You should hear a click or feel them securely latching.
- Test the Key Fob: Test the key fob functions (lock, unlock, remote start if applicable) to ensure the new battery is working correctly.

Frequently Asked Questions About Ford Key Fob Batteries
Q: What type of battery does a Ford key fob use?
A: Most Ford key fobs use a CR2032 battery. However, it’s always best to check the battery you remove from your key fob to confirm the exact type before purchasing a replacement. Some older or specific models might use different batteries like CR2025 or CR2016.
Q: How long does a Ford key fob battery last?
A: The lifespan of a Ford key fob battery typically ranges from 1 to 3 years. Factors like frequency of use, environmental conditions (extreme temperatures), and battery quality can affect battery life.
Q: How do I know when my Ford key fob battery is low?
A: You might notice several warning signs indicating a low key fob battery:
- Reduced Range: You need to be closer to your vehicle for the key fob to work.
- Intermittent Functionality: The key fob works sometimes but not others.

- Weak Signal: The vehicle may not respond to button presses immediately.
Q: Can I program my Ford keyless entry code myself?
A: Yes, you can program a personalized entry code for your Ford’s keyless entry system. Typically, this involves using the factory-set 5-digit code (usually found on a card in your owner’s manual or sometimes on the vehicle’s computer module) and then inputting your desired personal code through the keypad on the driver’s side door. Refer to your Ford owner’s manual for precise instructions for your specific model.
Q: What happens if my Ford key fob battery dies completely?
A: If your key fob battery is completely dead, you won’t be able to use the remote functions. However, you can still enter and start your vehicle using the emergency key blade you accessed in Step 1. Use the physical key to unlock the driver’s side door. To start the vehicle, you may need to hold the key fob close to the steering column or start button (refer to your owner’s manual for specific instructions on emergency starting procedures for your Ford model).
