2021 Lexus GX 460 Key Fob Battery Replacement: A Quick Guide

If you’re experiencing issues with your 2021 Lexus GX 460 key fob, like decreased range or unresponsive buttons, a dead battery might be the culprit. Luckily, replacing the key fob battery is a simple task that you can easily do yourself at home, saving you a trip to the dealership. This guide will walk you through the process step-by-step.

What you’ll need:

• A new CR2032 battery (easily found at most supermarkets, electronics stores, and online retailers)
• A small flathead screwdriver
• A few minutes of your time

How to replace the battery in your 2021 Lexus GX 460 key fob:

1. Locate the release button: On the back of your Lexus GX 460 key fob, you’ll find a small, sliding release button.
2. Release the valet key: Slide the release button while gently pulling out the valet key. This metal key is hidden inside the fob and can be used for manual door unlocking in emergencies.
3. Open the key fob: With the valet key removed, use your fingernail or the flathead screwdriver to carefully pry open the key fob casing. There’s a small indentation where the two halves of the fob meet. Apply gentle pressure and the casing should pop open.
4. Replace the battery: Inside, you’ll see the CR2032 battery. Note which side is facing up (usually the positive ‘+’ side) before removing it. Carefully remove the old battery and replace it with the new one, ensuring the positive ‘+’ side faces the same direction.
5. Reassemble the key fob: Align the two halves of the key fob casing and press them firmly together until you hear a click.
6. Reinsert the valet key: Slide the valet key back into its slot until it locks into place.
7. Test the key fob: Try locking and unlocking your Lexus GX 460 to ensure the new battery is working correctly.
