You probably know how frustrating it feels when your Ford key fob stops working, and you’re stuck wondering what to do next. You don’t need to rush to the dealer or spend money right away. You can fix it yourself! Changing the battery in your Ford key fob is simple and doesn’t take long. In this article, I’ll show you exactly how to replace the battery in your Ford key fob, step by step, using easy words and clear instructions. You’ll have your key fob working like new again in no time.
Open the Key Fob Case Carefully
The first thing you need to do is open the key fob case. Most Ford key fobs have a small notch or slot where you can gently pry the case open. It’s important to be very careful here because if you use too much force or the wrong tool, you might break the case or damage the buttons inside.
Start by finding a small flat tool like a flathead screwdriver or even a coin. Look closely at the edge of your key fob; you should see a seam or line where the two halves of the case meet. Insert your tool into that seam and gently twist or pry the halves apart. Sometimes the key fob might have a small latch or button you need to press to release the case.
If you don’t feel the case opening easily, stop and check again for a latch or button. Forcing it can damage the plastic. When it opens, you will see the battery inside. Take note of how the battery sits in the case because you will need to put the new one in the same way.
- Find the notch or seam on your key fob.
- Use a small flat tool like a screwdriver or coin.
- Carefully pry the two halves apart.
- Look for a latch or button if it doesn’t open easily.
- Notice the battery position inside.
Take Out the Old Battery Safely
Once you have your key fob open, you will see the old battery. Most Ford key fobs use small round batteries called coin cell batteries, usually CR2032 or CR2025. These are easy to find at any store.
To remove the old battery, be gentle. Sometimes the battery is held by a small clip or a tiny metal tab. Use your fingernail or the flat tool to carefully lift the battery out. Avoid touching any other parts inside the key fob to prevent damage.
When you take the battery out, check its type and number written on the battery. This is important because you need the exact same kind of battery to replace it. Don’t throw the old battery in the trash; batteries can be harmful to the environment. Find a recycling place for batteries or return it to a store that accepts old batteries.
- Identify the battery type and number.
- Carefully lift the battery out without touching other parts.
- Note the battery size and type for replacement.
- Keep the old battery for proper recycling.
Insert the New Battery Correctly
Now that you have the old battery out, it’s time to put the new one in. Make sure you have the exact same battery type as the old one. Look for the number on the battery package, like CR2032.
When inserting the new battery, pay attention to the positive (+) and negative (-) sides. Usually, the positive side faces up, but check how your old battery was placed before. Putting the battery the wrong way can make the key fob not work.
Gently press the battery into the slot until it fits snugly. Don’t force it or push too hard because the battery and the clip inside are small and delicate. Once the battery is in place, check if it is secure and not moving around.
- Use the exact battery type as the old one.
- Check positive (+) and negative (-) sides carefully.
- Place the battery as it was before.
- Press gently until the battery fits securely.
Close the Key Fob Case Properly
After you put in the new battery, the next step is to close the key fob case. This is important because if the case is not closed right, your key fob might stop working or the battery could fall out again.
Line up the two halves of the case carefully. Make sure any buttons or latches are in their right place. Press the halves together gently but firmly. You should hear a soft click when the case snaps back into place.
If your key fob has screws, don’t forget to screw them back in tight but not too tight. After closing, check the edges to make sure there are no gaps or openings. This keeps dust and dirt out and helps the key fob last longer.
- Align the two halves of the case correctly.
- Press gently until you hear a click.
- Screw in any screws if your key fob has them.
- Check for gaps to keep the inside clean.
Test the Key Fob to Make Sure It Works
Once the key fob is closed, it’s time to test if your new battery replacement worked. Stand near your Ford vehicle and press any button on the key fob. The car should respond by locking, unlocking, or starting depending on your key fob model.
If nothing happens, try pressing the buttons a few times or get closer to the car. If it still doesn’t work, check if the battery is inserted the right way. You can open the case again to make sure.
Sometimes, if the key fob still doesn’t work after battery replacement, the problem could be with the key fob itself and not the battery. But most of the time, a new battery fixes the issue.
- Press buttons near your car to test.
- Try pressing buttons multiple times.
- Make sure the battery is inserted correctly.
- Consider other problems if it still doesn’t work.
Dispose of Old Battery Safely and Maintain Your Key Fob
After you have confirmed that your new battery works, it’s time to deal with the old one. Never throw old batteries in the trash because they contain harmful chemicals. Instead, take the old battery to a battery recycling center or a store that accepts used batteries.
Proper disposal helps protect the environment and keeps harmful chemicals from polluting the earth. Many places, including electronics stores and recycling centers, accept old batteries for free.
To keep your key fob working well, avoid dropping it or exposing it to water. If your key fob gets dirty, clean it gently with a dry cloth. Don’t use water or strong cleaners because the inside parts are delicate. Regularly checking and replacing the battery every 1-2 years can keep your key fob ready to use.
- Take old batteries to recycling centers or stores.
- Don’t throw batteries in the trash.
- Keep your key fob clean and dry.
- Replace the battery regularly for best performance.
