Lexus IS250 Key Fob Battery Replacement: A Step-by-Step Guide

Once you have your supplies gathered, you’re ready to tackle this DIY project. Here’s how to replace the battery in your Lexus IS250 key fob:

Locate the release button on the back of your key fob. This is a small, indented button that is usually marked with a key symbol.
Press the release button and gently pull out the emergency key. The emergency key is a small, metal key that is hidden inside the key fob. You will use this to help pry open the key fob.
Insert the flat-head screwdriver into the seam of the key fob where the emergency key was removed. Gently twist the screwdriver to separate the two halves of the key fob. Be careful not to damage the plastic.
Carefully remove the old battery. Note which side of the battery is facing up, as the new battery will need to be installed in the same direction.
Insert the new battery into the key fob, making sure that the positive (+) side is facing up.
Align the two halves of the key fob and press them together until you hear a click.
Test the key fob to make sure that it is working properly.
