Do I Need a New Key Fob Battery?

Key fob batteries don’t last forever. If you’re noticing any of the following, it might be time for a replacement:

Decreased Range: Your car only responds to the key fob at very close range.
Intermittent Functioning: The key fob works sometimes, but not others.
No Response: The car doesn’t respond to any key fob commands.

What You’ll Need:

A fresh CR2032 battery (easily found at most stores)
A small flathead screwdriver or a plastic pry tool

Locate the Key Fob Release: On the back of your key fob, find the small button or tab.
Release the Mechanical Key: Press the button and slide the mechanical key out of the fob.
Open the Key Fob: Use your flathead screwdriver or pry tool to gently pry open the key fob casing. There’s usually a small notch where the two halves of the fob connect. Be careful not to damage the casing.
Remove the Old Battery: Inside, you’ll see the CR2032 battery. Carefully remove it by gently prying it out with your screwdriver or pry tool.
Insert the New Battery: Place the new CR2032 battery into the fob, making sure the positive (+) side faces up.
Reassemble the Key Fob: Align the two halves of the key fob casing and press them together firmly until they snap back into place.

Still Having Issues?

Sometimes, a new battery isn’t the only solution. Here are a few other things to consider if your key fob is still acting up:
