1997 Toyota 4Runner Key Fob Battery

If your 1997 Toyota 4Runner key fob is acting up, chances are you need a new battery. This quick guide will walk you through everything you need to know about your 1997 Toyota 4runner Key Fob Battery, from choosing the right replacement to installing it yourself.

Finding the Right 1997 Toyota 4Runner Key Fob Battery

So, your key fob is giving you grief. Maybe the lock/unlock buttons are sluggish, or the panic alarm isn’t as loud as it used to be. A dead or dying battery is the most likely culprit. For a 1997 Toyota 4Runner, you’ll need a CR2016 or CR2032 battery. You can usually find these at any electronics store, pharmacy, or even some grocery stores. Don’t grab just any battery, though. Make sure it’s a reputable brand to ensure it lasts.

CR2016 vs. CR2032: What’s the Difference?

Both batteries are lithium coin cell batteries, but the CR2032 is slightly thicker than the CR2016. While your 4Runner likely uses a CR2016, some owners have reported success using a CR2032. However, using a thicker battery might put stress on the key fob case and could potentially damage it over time. Sticking with the recommended CR2016 is generally the best way to go.

How to Replace Your 1997 Toyota 4Runner Key Fob Battery

Replacing the battery is a simple DIY job. You don’t need any special tools, just a small flathead screwdriver or even a coin. Here’s a step-by-step guide:

Locate the small notch or slot on the key fob casing. This is usually on the side or back.
Carefully insert the flathead screwdriver or coin into the notch and gently pry open the casing. Be careful not to damage the plastic.
Once the casing is open, you should see the battery. Note its orientation (positive side up or down) before removing it.
Gently pry the old battery out of its compartment.
Insert the new CR2016 battery into the compartment, making sure it’s oriented correctly, matching the old battery’s position.
Snap the key fob casing back together. Make sure it closes securely.

That’s it! You’ve successfully replaced your 1997 Toyota 4Runner key fob battery.
