Key fob technology can seem like a mystery at first glance. But fortunately, key fobs are powered by a very simple battery. When your Ford key fob battery weakens or completely dies, it takes just minutes to replace it.
What kind of battery goes in a Ford key fob?
Most Ford key fobs operate on two CR2032 batteries, which are 3-volt lithium batteries. Though Ford key fobs can be square, rounded or rectangular, almost all use the same CR2032 batteries. An exception is the Ford Smart Key with Pull-out Valet Key, which comes with newer vehicles such as the Edge and Mustang. This key fob requires two CR2450 batteries.
Where Can I Find a Battery and How Much Will It Cost?
Key fob batteries are easy to find at everyday retail outlets and e-commerce venues. Anywhere that sells batteries is likely to carry the CR2032 and CR2450. Prices for a two-pack generally run from $5 to $6, while a four-pack can cost as low as $8. The batteries become even more cost-efficient when buying in bulk packs of 10, 15 or 20.
Another option for economically purchasing 3-volt lithium batteries, also known as “coin” batteries, is to look for store brands such as Amazon Basic. As long as the manufacturer is reputable, the quality is typically comparable to major battery brands.
Steps for Replacing a Ford Key Fob Battery:
Switching out the old Ford key fob batteries is a breeze. You only need a small flathead screwdriver and the new CR2032 or CR2450 lithium batteries. You’ll be powered up and ready to ride in a flash.
Step 1: Look for a release button on the back of the Ford key fob. Press the button to open the back cover.
Step 2: Insert the tip of a small flathead screwdriver into the slot, twisting it lightly to open the remote. This reveals the two coin batteries that power the key fob.
Step 3: Remove the top battery. You’ll see a small piece of white paper, with the second battery beneath the paper. Remove the second battery. The screwdriver can be useful for helping you pop out the two batteries.
Step 4: Insert the two new batteries, making sure to have the negative side facing toward you.
Step 5: Replace all pieces and the outer cover. Test the key fob to verify that the new batteries are installed and working properly.
With fresh new batteries, you’re ready to roll again!
