How to Change the Battery in a Lexus Key Fob – Four Simple Steps

When it comes time for Lexus key battery replacement, you will need a flathead screwdriver and a CR2032 lithium battery. When you have what you need, simply follow the instructions here: 

1. Push the release button on the side of the key fob. Take out the emergency key blade.
