Just like any battery-powered device, the key fob for your 2019 Ford vehicle will eventually need a battery replacement. You might find that your remote control transmitter, or key fob, becomes less responsive or stops working altogether. Before you consider more complex solutions, replacing the battery is a simple and often effective first step. This guide will walk you through the process of changing the battery in your 2019 Ford key fob, allowing you to do it yourself at home with ease.
Is It Time to Change Your 2019 Ford Key Fob Battery?
Ford vehicles are designed to notify you when your key fob battery is running low. Keep an eye on your instrument cluster or display screen for a message indicating a low key fob battery. This warning is your signal to replace the battery soon to avoid being locked out or unable to start your vehicle remotely. Even without a warning message, if you notice your key fob is working intermittently or requires you to be closer to your car than usual, a battery change is likely needed.
What You’ll Need to Change Your Key Fob Battery
Before you begin, gather these simple tools:
- A new CR2032 battery: This is the standard battery type for most 2019 Ford key fobs. You can find these batteries at most drug stores, supermarkets, and electronics stores.
- A small flathead screwdriver or a coin: This will be used to gently pry open the key fob casing.
Step-by-Step Guide to Battery Replacement
Follow these steps to replace the battery in your 2019 Ford key fob:
-
Release the Key Blade: Locate the key blade release mechanism on your key fob. Some models have a button that you need to press and hold to release the blade, while others might require you to manually slide a small latch. Remove the metal key blade from the fob.
-
Open the Key Fob Casing: With the key blade removed, you’ll see a small slot or seam where you can open the key fob. If your key fob required you to release the key blade with a button, insert your small flathead screwdriver into this slot. Gently twist the screwdriver to pry the two halves of the key fob casing apart. If your model requires manual blade removal, you can use a small coin instead. Wedge the edge of the coin into the gap where the key blade was located and twist gently to separate the casing. Work carefully to avoid scratching the plastic.
-
Remove the Old Battery: Once the key fob is open, you’ll see the battery. It’s usually held in place quite snugly. Use the tip of your flathead screwdriver to gently pry the old battery out of its compartment. Be mindful of the battery’s orientation – note which side is facing up (usually the positive (+) side).
-
Insert the New Battery: Take your new CR2032 battery and insert it into the battery compartment. Ensure the positive (+) side of the battery is facing upwards, matching the orientation of the old battery you just removed. Push the battery firmly into place until it is secure.
-
Close the Key Fob Casing: Carefully snap the two halves of the key fob casing back together. Press firmly until you hear or feel a click, ensuring the casing is fully closed and secure.
-
Test Your Key Fob: Reinsert the key blade (if removed) and test your key fob by pressing the lock, unlock, and remote start buttons. Your 2019 Ford should respond as expected, indicating a successful battery replacement.
Troubleshooting: Key Fob Still Not Working?
If your key fob still doesn’t work after replacing the battery, consider these possibilities:
- Battery Orientation: Double-check that you inserted the new battery with the positive (+) side up.
- Battery Type: Ensure you used a CR2032 battery. Using a different type might not provide the correct voltage.
- Battery Contacts: Inspect the metal contacts in the key fob battery compartment. Make sure they are clean and making good contact with the battery. If they look corroded, you can gently clean them with a cotton swab and a tiny bit of rubbing alcohol.
- Key Fob Damage: If the key fob was dropped or damaged, there might be an internal issue beyond battery replacement. In this case, you may need to consult a Ford dealer or a locksmith specializing in car key fobs.
Tips to Prolong Your Key Fob Battery Life
While key fob batteries are designed to last, you can take steps to potentially extend their lifespan:
- Avoid Extreme Temperatures: Extreme heat or cold can impact battery performance. Try to avoid leaving your key fob in direct sunlight or freezing temperatures for extended periods.
- Limit Button Presses: Unnecessary button presses can drain the battery over time. Be mindful of accidentally pressing buttons when the fob is in your pocket or bag.
Changing the battery in your 2019 Ford key fob is a straightforward process that can save you time and money compared to visiting a dealership for a simple issue. By following these steps, you can quickly restore your key fob’s functionality and get back on the road with confidence.
