How to Replace Battery in a Toyota Key Fob

A dead key fob battery can be a major inconvenience, leaving you stranded and unable to unlock your Toyota. Thankfully, replacing the battery in your Toyota key fob is a quick and easy process that you can do yourself.

This comprehensive guide will walk you through the steps to replace the battery in your Toyota key fob, getting you back on the road in no time.

What You’ll Need

Before you begin, gather the following items:

  • A new CR2032 battery (this is the most common type of battery used in Toyota key fobs)
  • A small flat-head screwdriver or a plastic pry tool
  • Your Toyota key fob

How to Replace the Battery

Follow these simple steps to replace the battery in your Toyota key fob:

  1. Identify the Battery Compartment: Most Toyota key fobs have a small release button or notch on the back. This button or notch releases the battery compartment cover.

  2. Open the Battery Compartment: Using a small flat-head screwdriver or a plastic pry tool, gently insert it into the notch or press the release button to open the battery compartment. Be careful not to damage the key fob or your tools.

  3. Remove the Old Battery: Once the compartment is open, you’ll see the old battery. Gently pry it out, noting the orientation of the positive (+) and negative (-) sides.

  4. Insert the New Battery: Align the positive (+) side of the new CR2032 battery with the positive (+) marking inside the battery compartment. Gently press it into place until it clicks.

  5. Close the Battery Compartment: Align the cover and press it back into place until you hear a click. Make sure the cover is securely closed.

  6. Test the Key Fob: Press the buttons on your key fob to ensure it’s working properly. If the buttons still don’t work, double-check that the new battery is properly installed and that the terminals are clean.

Troubleshooting Tips

If you’re still experiencing problems with your Toyota key fob after replacing the battery, here are some additional tips:

  • Check the Battery: Make sure you’ve installed the correct type of battery (CR2032) and that it’s fresh and not dead.

  • Clean the Contacts: Over time, the battery contacts inside the key fob can become dirty or corroded. Use a cotton swab and a small amount of rubbing alcohol to clean them.

  • Resync the Key Fob: Some Toyota models require you to resync the key fob to the car after replacing the battery. Consult your owner’s manual for specific instructions on how to do this for your model.

  • Consult a Professional: If you’ve tried all of these steps and your key fob is still not working, it’s best to consult a qualified automotive locksmith or your Toyota dealership for further assistance. They have the expertise and tools to diagnose and fix any underlying issues.
