Replacing the battery in your 2018 Ford Focus key fob is a simple process that you can easily do yourself. Whether your key fob has stopped working entirely or is just starting to act up, a quick battery swap is often all you need.
How to Tell if Your Key Fob Battery is Dying
Before you start digging around for a new battery, it’s good to be sure that the battery is actually the issue. Here are some telltale signs that your key fob battery is dying:
- Decreased Range: You find yourself having to stand closer to your car for the key fob to work.
- Intermittent Functioning: The key fob sometimes works and sometimes doesn’t, requiring multiple button presses.
- Warning Messages: Your Ford Focus dashboard may display warnings like “Key Fob Not Detected.”
What You’ll Need
- A new CR2032 battery (you can often find these at grocery stores, electronics stores, and auto parts stores)
- A small flat-head screwdriver
Replacing the Battery: Step-by-Step
- Open the Key Fob: Look for a small slot on the back of your key fob. Insert the flat-head screwdriver into the slot and gently pry open the casing. You might hear a slight click when it separates.
- Locate the Battery: Inside, you’ll see the round, flat CR2032 battery. Carefully remove it by prying it up from the side with your fingernail or the screwdriver.
- Install the New Battery: Insert the new battery, making sure the positive (+) side faces up (the positive side is usually marked on the battery).
- Reassemble the Key Fob: Align the two halves of the key fob and press them firmly together until you hear a click, indicating it’s securely closed.
Testing the New Battery
Once you’ve replaced the battery, test the key fob by trying to lock and unlock your Ford Focus. Everything should work as normal!
Still Having Problems?
If replacing the battery doesn’t solve the problem, there could be a more significant issue with your key fob or your car’s keyless entry system. In this case, it’s best to consult your Ford dealership or a qualified automotive locksmith.
Expert Insight: “While replacing the key fob battery yourself can save you a few bucks, always be careful when prying open the fob. Too much force can damage the casing.” – John Davis, Senior Automotive Technician
