How to Change Battery in 2022 Toyota Tundra Key Fob

A dead key fob battery can be a major inconvenience, leaving you stranded and unable to unlock your 2022 Toyota Tundra. Fortunately, replacing the battery is a quick and easy task that can be done at home with just a few simple tools. This guide will walk you through the process step-by-step, so you can get back on the road in no time.

What You’ll Need

Before you begin, gather the following items:

• A new CR2032 battery
• A small flat-head screwdriver
• Your 2022 Toyota Tundra key fob

Step-by-Step Guide

Follow these instructions carefully to replace your key fob battery:

1. Locate the release button: On the back of your key fob, you’ll find a small, recessed button.
2. Release the mechanical key: Using the flat-head screwdriver, gently press the release button. While pressing, slide the mechanical key out of the fob.
3. Open the fob casing: With the mechanical key removed, you can now separate the two halves of the key fob casing. Use your fingernail or the flat-head screwdriver to carefully pry open the casing along the seam.
4. Remove the old battery: Once the casing is open, you’ll see the old CR2032 battery inside. Carefully remove it by gently prying it out with your fingernail or the flat-head screwdriver.
5. Install the new battery: Insert the new CR2032 battery into the compartment, making sure the positive (+) side faces up.
6. Reassemble the fob: Snap the two halves of the key fob casing back together. You should hear a secure click when they are properly aligned.
7. Reinsert the mechanical key: Slide the mechanical key back into its slot on the fob until it clicks into place.
8. Test the key fob: Make sure your newly powered key fob is working by locking and unlocking your Tundra, as well as using the panic button.

Troubleshooting

If your key fob is still not functioning correctly after replacing the battery, consider these possible solutions:

• Check the battery installation: Ensure the new battery is correctly installed with the positive (+) side facing up.
• Clean the battery contacts: Use a cotton swab and rubbing alcohol to clean the battery contacts inside the fob. Corrosion can prevent proper connection.
• Reprogram the key fob: In some cases, you may need to reprogram your key fob to your Tundra after replacing the battery. Refer to your owner’s manual for specific instructions on how to do this.
