Understanding Your Lexus Key Fob
Lexus key fobs are sophisticated pieces of technology, combining keyless entry, remote start, and sometimes even a panic button.

How to Open Lexus Key Fob Battery: A Step-by-Step Guide
While the specific design may vary slightly depending on the Lexus model and year, the general process for opening the key fob to access the battery is similar. Here’s a step-by-step guide:
- Locate the release button: Look for a small button or switch on your key fob, usually near where the metal key inserts. This button is often marked with a lock icon or an arrow.
- Press the release button: Using your fingernail or a small flathead screwdriver, gently press the release button.
- Release the valet key: While holding the release button, slide the metal valet key out of the fob.
- Separate the fob halves: With the valet key removed, you should be able to gently pry open the two halves of the key fob casing. A small flathead screwdriver or a plastic pry tool can be helpful here. Be careful not to damage the casing.
- Locate the battery: Once the fob is open, you’ll see the battery, typically a small, round CR2032 or similar type.
Replacing the Battery
Once you’ve accessed the battery, replacing it is straightforward. Carefully remove the old battery, noting its orientation. Insert the new battery, ensuring it’s positioned correctly. Snap the two halves of the key fob back together. Test the fob’s functionality. If it’s working correctly, reinsert the valet key.
