Your Ford vehicle’s key fob is an indispensable tool, providing convenient remote access to lock and unlock your doors, and sometimes even start your engine. These modern conveniences are powered by small batteries, which, like all batteries, will eventually need replacing. Knowing how to open your Ford key fob is a simple yet essential skill for any Ford owner, saving you time and potentially money. This guide will walk you through the process of opening your Ford key fob to replace the battery, ensuring you can keep your key fob functioning smoothly.
Step 1: Identify Your Key Fob Type and Locate the Key Blade Release
Ford key fobs come in various designs, but most share a similar mechanism for opening. The first step is to locate the key blade release. This is usually a small button or latch, often metallic, situated at the top or back of the key fob, where the mechanical key blade is housed.
For some Ford models, you may need to manually slide a small latch to release the key blade. Other models feature a more prominent button that, when pressed, allows you to pull the key blade out.

Action: Carefully examine your Ford key fob to identify the key blade release mechanism. If it’s a button, press and hold it while gently pulling the key blade away from the fob. If it’s a latch, slide it and then remove the key blade. Set the key blade aside in a safe place.
Step 2: Prying Open the Key Fob Casing
With the key blade removed, you’ll now need to carefully open the key fob casing to access the battery. This typically involves gently prying the two halves of the fob apart.
For this step, a small flathead screwdriver or a thin coin (like a penny or nickel) will be useful. Look for a small slot or seam on the side of the key fob, usually where the key blade was originally inserted. This seam is designed as the opening point.

Action: Insert the tip of your flathead screwdriver or the edge of your coin into the slot or seam. Gently twist the screwdriver or coin to apply pressure and begin to separate the two halves of the key fob casing. Work your way around the seam carefully, applying gentle pressure until the casing pops open. Avoid using excessive force, as this could damage the key fob.
Step 3: Removing the Old Battery
Once the key fob casing is open, you will see the battery. Ford key fobs commonly use small, round, flat batteries, often CR2032 or CR2025 types. Take note of the battery type currently in your key fob before removing it, so you can purchase the correct replacement.
The battery is usually held in place by small clips or a tight fit. You may be able to gently pry it out with your fingertip. If it’s snug, you can use the flathead screwdriver again, being very careful not to damage the battery compartment or any of the surrounding circuitry.

Action: Carefully remove the old battery from the key fob. Note the orientation of the battery – specifically, which side is facing up (usually marked with a “+” sign). This is crucial for installing the new battery correctly. Dispose of the old battery responsibly according to local regulations for battery disposal.
Step 4: Installing the New Battery
Now it’s time to install the new battery. Ensure you have the correct type of replacement battery, matching the type you noted in the previous step.
Action: Place the new battery into the battery compartment, ensuring it is oriented in the same way as the old battery was removed (positive side up, if applicable). Press down gently to ensure it is securely seated in the compartment.
Step 5: Closing the Key Fob Casing
With the new battery in place, carefully align the two halves of the key fob casing.
Action: Press the two halves of the casing firmly together until they snap back into place. Ensure there are no gaps and that the casing is securely closed.
Step 6: Testing Your Key Fob
Finally, reinsert the mechanical key blade back into the key fob until it clicks into its locked position.
Action: Test your key fob by attempting to lock and unlock your Ford vehicle remotely. If your car responds as expected, you have successfully replaced the key fob battery! If it doesn’t work immediately, double-check that the battery is correctly installed and of the correct type. If issues persist, consult your Ford owner’s manual or contact a Ford dealership for assistance.
Frequently Asked Questions
How can I program my Ford’s personal entry keyless code?
To program or reset your Ford’s keyless entry code, you’ll typically need to use the factory-set code, which is usually found on a card in your owner’s manual or can be obtained from a Ford dealer.
- Enter the factory-set 5-digit code using the keypad on your driver’s side door.
- Within 5 seconds of entering the factory code, press the “1•2” button on the keypad.
- Enter your desired new 5-digit personal entry code.
- Press the “1•2” button again to save your new personal code.
The doors should lock and then 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 using the key fob. You’ll need to use the physical key blade to manually unlock your car door. While most Ford vehicles include an emergency key blade within the fob for this purpose, relying solely on the physical key can be inconvenient and reduces the security benefits of remote locking. Furthermore, features like remote start (if equipped) will also cease to function.
Will replacing the battery erase my key fob programming?
No, replacing the battery in your Ford key fob should not erase its programming to your vehicle. The key fob’s programming is stored in a separate memory chip and is not dependent on the battery for retention. You should be able to replace the battery and have your key fob function normally without needing to reprogram it.
How often should I replace my Ford key fob battery?
The lifespan of a Ford key fob battery can vary depending on usage and environmental factors, but typically they last for 2 to 3 years. If you notice the range of your key fob decreasing, or if it becomes less reliable, it’s a good indication that the battery is getting weak and should be replaced soon. It’s proactive to replace it every two years to avoid being caught off guard by a dead battery.
Can I use any battery in my Ford key fob?
No, you should always use the correct type of battery specified for your Ford key fob. Using the wrong type of battery might result in improper function or even damage to the key fob. Refer to your owner’s manual or check the markings on the old battery to determine the correct replacement type (e.g., CR2032, CR2025).
By following these simple steps, you can easily open your Ford car key fob and replace its battery, ensuring you continue to enjoy the convenience and security of your remote keyless system.
