Understanding Your Lexus Key Fob
Lexus key fobs, like most car key fobs, are powered by small batteries that eventually wear out. Recognizing the signs of a dying battery is crucial. These signs can include: decreased remote range, dim LED lights on the fob, or the need to be unusually close to your car for the key fob to function. Before you begin the replacement process, it’s important to identify the type of key fob you have. Lexus offers several different key fob designs, and the battery replacement procedure may vary slightly between models.

Gathering the Necessary Tools
Replacing your Lexus key fob battery requires only a few simple tools. You will need a small flathead screwdriver or a similar tool for prying open the key fob casing, and of course, a new CR2032 or CR2450 battery (check your owner’s manual for the correct battery type for your specific model). Having a small tray or container handy can also be helpful to keep the small parts organized during the process.
Step-by-Step Guide: How to Replace Lexus Key Fob Battery
The following steps provide a general guideline for replacing the battery in most Lexus key fobs. However, always consult your owner’s manual for model-specific instructions.
- Release the valet key: Most Lexus key fobs have a small release button or switch that allows you to slide out the valet key. Locate this button and release the valet key.
- Open the key fob casing: Use the flathead screwdriver to carefully pry open the key fob casing. Start by inserting the screwdriver into the small notch or groove designated for this purpose. Gently pry open the casing, being careful not to damage the plastic.
- Locate and remove the old battery: Once the casing is open, you should see the battery. It’s usually a small, round, silver disc. Carefully remove the old battery using your screwdriver or fingernails.
- Install the new battery: Insert the new CR2032 or CR2450 battery into the battery compartment, ensuring the positive (+) side is facing up.
- Close the key fob casing: Align the two halves of the key fob casing and press them together firmly until they click shut.
- Test the key fob: Try locking and unlocking your car with the key fob to ensure the new battery is working correctly.
