How to Change Battery Toyota Key Fob

If your Toyota key fob has stopped working reliably, or the lock/unlock buttons require multiple presses to work, it’s likely time to replace the battery. Fortunately, changing the battery in your Toyota key fob is a quick and easy process you can do yourself at home. No need for expensive trips to the dealership! This guide will walk you through the steps, providing helpful tips and addressing common questions along the way.

Let’s get started!

What you’ll need to change your Toyota key fob battery:

A brand new CR2032 battery: These are readily available at most grocery stores, pharmacies, and online retailers.
A small flat-head screwdriver: This will help you pry open the key fob casing.
Your Toyota key fob: It seems obvious, but we want to make sure you have it handy!

Steps to change the battery in your Toyota key fob:

Identify the release button: Most Toyota key fobs have a small sliding button on the back. Locate this button – it’s usually marked with a lock symbol.
Release the mechanical key: Slide the release button and gently pull out the mechanical key from the fob.
Separate the key fob halves: Use your fingernail or the flat-head screwdriver to carefully pry open the key fob casing. Start at the notch where the mechanical key was inserted, and gently work your way around the edges.
Locate and remove the old battery: Once open, you’ll see the battery. Note its position – the positive (+) side usually faces up. Carefully remove the old battery using your fingernail or the screwdriver.
Install the new battery: Insert the new CR2032 battery, ensuring the positive (+) side faces the same direction as the old one.
Reassemble the key fob: Align the two halves of the key fob casing and press them together firmly until you hear a click, indicating it’s securely closed.
Reinsert the mechanical key: Slide the mechanical key back into its slot until it locks in place.
Test your key fob: Try locking and unlocking your car doors to ensure the new battery works properly.

“My Toyota key fob still isn’t working after changing the battery! What now?”

Don’t worry! There are a few things you can try:

Check the battery orientation: Ensure the new battery is installed correctly with the positive (+) side facing up.
Clean the battery contacts: Over time, battery contacts can build up grime. Gently clean them with a cotton swab and a bit of rubbing alcohol.
Try reprogramming your key fob: Refer to your Toyota owner’s manual for instructions on how to reprogram your key fob after a battery change, as some models require it.

If you’ve tried these troubleshooting steps and your key fob is still not functioning, there may be a more significant issue. Consider contacting your local Toyota dealership or a qualified automotive locksmith for assistance.
