2013 Toyota Prius Key Fob Battery Replacement: A Quick Guide

If you’re experiencing issues with your 2013 Toyota Prius key fob, like having to stand closer to your car to unlock it or dealing with inconsistent locking and unlocking, a dead battery might be the culprit. Thankfully, replacing the key fob battery in a 2013 Toyota Prius is a simple DIY task you can tackle in minutes.

What You’ll Need:

  • A new CR2032 battery (widely available at supermarkets, electronics stores, and online)
  • A small flat-head screwdriver

How to Replace the Battery:

  1. Locate the release button: On the back of your Prius key fob, find the small, indented button.
  2. Release the mechanical key: Press the release button and gently slide the mechanical key out of the fob.
  3. Open the fob: Use the tip of your flat-head screwdriver to carefully pry open the key fob casing at the seam where the mechanical key was inserted. Be gentle to avoid damaging the casing.
  4. Replace the battery: Inside, you’ll see the CR2032 battery. Carefully remove it and note which side was facing up. Place the new battery in the same orientation.
  5. Reassemble the fob: Align the two halves of the key fob and press them firmly together until you hear a click, indicating it’s securely closed.
  6. Reinsert the mechanical key: Slide the mechanical key back into its slot on the fob.
  7. Test the key fob: Try locking and unlocking your Prius to make sure the new battery works.

Pro Tip from John Miller, Senior Automotive Technician: “When handling the new battery, avoid touching the flat surfaces. This helps to prevent transferring oils from your fingers, which can reduce the battery’s lifespan.”
