Is your 2001 Lexus ES300 key fob not working like it used to? You might be facing the common issue of a dead or dying key fob battery. Don’t worry, replacing the battery in your Lexus ES300 key fob is a straightforward process you can easily handle yourself, saving you time and money compared to dealership service. This guide will walk you through each step, ensuring you can quickly get your key fob back in perfect working order.
A failing key fob battery can manifest in several ways. You might notice that you need to be closer to your vehicle than usual for the remote to function. Alternatively, the range of your remote start might decrease significantly, or in some cases, the buttons might become unresponsive altogether. These are clear indicators that it’s time for a battery replacement. Ignoring these signs can lead to complete key fob failure, potentially leaving you locked out of your vehicle or unable to start it remotely.
Replacing the battery in your 2001 Lexus ES300 key fob is a simple DIY task that requires minimal tools. Typically, you will need a small flathead screwdriver or a similar prying tool, and of course, the correct replacement battery. The battery type commonly used in 2001 Lexus ES300 key fobs is the CR2016 or CR2025 3V lithium coin cell battery. It’s always best to double-check your owner’s manual or the existing battery in your key fob to confirm the exact type before purchasing a replacement. You can find these batteries at most drugstores, supermarkets, auto parts stores, and online retailers.
Let’s get started with the battery replacement process:
Step 1: Locate the Notch and Open the Key Fob
Examine your 2001 Lexus ES300 key fob closely. You’ll typically find a small notch or seam on the side or bottom of the fob. This is where you’ll need to insert your flathead screwdriver or prying tool. Gently insert the tip of your screwdriver into the notch and carefully twist or pry to separate the two halves of the key fob casing. Avoid using excessive force, as you could damage the plastic casing. Work your way around the seam if necessary until the case begins to split open.
Step 2: Carefully Separate the Key Fob Halves
Once you’ve created a gap in the casing, gently pull the two halves of the key fob apart. Inside, you’ll see the circuit board and the battery. Take note of the battery’s orientation before removing it, paying attention to which side is facing up (+ or -). This will ensure you install the new battery correctly.
Step 3: Remove the Old Battery
The battery is usually held in place by small clips or within a battery holder. You might be able to gently pry it out with your fingertip, or you can use the tip of your flathead screwdriver to carefully nudge it out. Be careful not to damage the circuit board while removing the old battery.
Step 4: Install the New Battery
Take your new CR2016 or CR2025 battery and install it in the key fob, ensuring that the polarity matches the original battery’s orientation (positive side up or down as noted in Step 2). Push the battery firmly into place until it is securely seated in the holder or under the clips.
Step 5: Reassemble the Key Fob
Carefully align the two halves of the key fob casing and press them back together until they snap securely into place. Ensure there are no gaps and the casing is fully closed.
Step 6: Test Your Key Fob
Once reassembled, test your key fob by attempting to lock and unlock your 2001 Lexus ES300, and try the remote start function if your vehicle is equipped with it. If everything works as expected, you’ve successfully replaced your 2001 Lexus Es300 Key Fob Battery!

If your key fob still doesn’t work after replacing the battery, double-check that you installed the new battery with the correct polarity and that the battery type is correct.
