A dead key fob battery can leave you stranded and frustrated. Luckily, replacing the battery in your Ford key fob is a simple task that anyone can do at home with just a few common household tools. This guide will walk you through the process step-by-step and have you back on the road in no time.
What You’ll Need to Replace Your Ford Key Fob Battery
Before you get started, gather the following items:
- A small flathead screwdriver or a coin
- A replacement battery (CR2032 3V lithium battery)
Pro Tip: Keep a spare CR2032 battery in your glove compartment or at home. That way, you’ll be prepared if your key fob battery dies unexpectedly.
How to Open Your Ford Key Fob
Ford key fobs come in a variety of shapes and sizes, but the method for opening them is generally the same.
-
Locate the small release button or notch on the side of the key fob. This is usually located near the key ring.
-
Insert the tip of your flathead screwdriver or the edge of a coin into the notch or press the release button.
-
Gently pry open the key fob. You may hear a slight click as the fob separates.
Identifying and Replacing the Battery
-
Carefully separate the two halves of the key fob. Inside you will find the battery.
-
Note the orientation of the battery. Pay attention to which side is facing up (positive (+) or negative (-)).
-
Use your fingernail or the flathead screwdriver to gently pry the battery out of its compartment.
-
Insert the new battery, making sure it’s facing the same direction as the old one.
Important: Avoid touching the top and bottom of the new battery as this can shorten its lifespan. Handle it by the edges.
Closing the Key Fob and Testing
-
Align the two halves of the key fob and press them firmly together until you hear a click.
-
Test all the buttons on your key fob to make sure it’s working properly.
If your key fob still isn’t working after replacing the battery, there may be a more serious issue. You can consult your owner’s manual or contact a qualified automotive locksmith or dealership for further assistance.
