Is your Ford Explorer key fob acting up? Before you schedule a tow to the dealership, a dead key fob battery might be the culprit. Don’t worry, replacing it is a simple DIY task you can tackle at home. This comprehensive guide covers everything you need to know about your Ford Explorer key fob battery, from identifying the signs of a dying battery to replacing it yourself and some handy tips for prolonging its lifespan.
How to Tell if Your Ford Explorer Key Fob Battery is Dying
A failing key fob battery can manifest in several ways. Here are some common signs:
- Decreased Range: Do you find yourself standing closer to your vehicle than usual to lock or unlock it? This is often the first sign of a weakening key fob battery.
- Intermittent Functionality: Does your key fob sometimes work and sometimes not, even when pressing the buttons repeatedly? This inconsistency points towards a battery on its last legs.
- No Response: The most obvious sign – a completely unresponsive key fob usually means the battery has died entirely.
- Dashboard Warning: Some Ford Explorers might display a “Low Key Fob Battery” warning message on the dashboard, providing a clear indication of the issue.
What Battery Does a Ford Explorer Key Fob Take?
Most Ford Explorer key fobs, regardless of the year, use a CR2032 battery. This small, coin-shaped battery is readily available online, at auto parts stores, and even in many grocery stores.
How to Change the Battery in a Ford Explorer Key Fob: A Step-by-Step Guide
Replacing the battery in your Ford Explorer key fob is a straightforward process. Here’s how to do it:
- Locate the Key Release: Look for a small button or switch on your key fob. This releases the physical key from the fob.
- Remove the Physical Key: Press the key release and slide out the physical key.
- Open the Key Fob: Use the notch where the physical key was to carefully pry open the key fob casing. You can use a flathead screwdriver or even a coin for this.
- Remove the Old Battery: The CR2032 battery sits in a designated slot. Gently pry it out using your fingernail or a small flat tool.
- Install the New Battery: Insert the new CR2032 battery into the slot, ensuring the positive (+) side faces up.
- Reassemble the Key Fob: Align the two halves of the key fob casing and press them together until you hear a click, indicating they’re securely closed.
- Reinsert the Physical Key: Slide the physical key back into its slot on the key fob.
- Test the Key Fob: Ensure the battery replacement was successful by testing all the buttons (lock, unlock, panic) to confirm they’re functioning correctly.
Tips for Longer Key Fob Battery Life
- Avoid Frequent Short Trips: Short trips prevent your car battery (which charges the key fob battery) from fully charging.
- Don’t Leave Your Keys Near Appliances: Electromagnetic fields from appliances can interfere with your key fob and drain its battery faster.
- Store Your Key Fob Properly: Keep your key fob in a cool, dry place away from direct sunlight and extreme temperatures.
When to Consult a Professional
While replacing the key fob battery is a simple DIY task, there are instances where it’s best to seek professional help:
- The Key Fob Still Doesn’t Work: If replacing the battery doesn’t solve the problem, there might be a more complex issue with the key fob itself, requiring professional diagnosis and repair.
- Physical Damage: A physically damaged key fob (like cracks or water damage) might need more than just a battery replacement.
