How to Change Battery in Lexus GX 460 Key Fob

If you’re experiencing issues with your Lexus GX 460 key fob, like decreased range or unresponsive buttons, a dying battery might be the culprit. Luckily, changing the battery in your Lexus GX 460 key fob is a quick and easy process you can do yourself at home. This guide will walk you through each step, ensuring you get back on the road with a fully functioning key fob in no time.

Identifying Your Lexus GX 460 Key Fob Type

Before you start, it’s crucial to determine which type of key fob your Lexus GX 460 uses, as the battery replacement process slightly differs. There are two primary types:

Standard Key Fob: This fob has a flip-out key and separate lock, unlock, and panic buttons.
Smart Key Fob: This keyless entry fob might not have a visible metal key and often includes features like push-button start.

Once you’ve identified your key fob type, gather the necessary tools:

A small flat-head screwdriver
A new CR2032 battery (for most Lexus key fobs)
