What You Will Need

Before you start, gather the following items:

Step 1: Prepare Your Workspace

Find a flat and well-lit surface where you can comfortably work on your Lexus key. Clean the area to prevent any dirt or debris from interfering with the process. Lay out your tools and the replacement battery within easy reach.

Step 2: Open the Key

Hold your Lexus key with the buttons facing down and locate the small screw on the back of the key. Use the appropriate screwdriver to carefully unscrew the screw and set it aside in a safe place. Gently separate the two halves of the key, taking care not to damage any internal components.

Step 3: Remove the Old Battery

Inside the key, you will see a small compartment that houses the battery. Take note of the position of the old battery and carefully remove it by sliding it out or popping it out using a small tool like a flathead screwdriver or your fingernail. Dispose of the old battery properly according to local regulations.

Step 4: Insert the New Battery

Take the new battery and make sure it matches the old one in terms of type and size. Align the new battery with the correct polarity (+/-) and carefully slide it into the compartment, ensuring it fits securely. Make sure the battery is seated properly to guarantee proper functioning of your key.

Step 5: Reassemble the Key

Line up the two halves of the key, making sure all the buttons are aligned correctly. Press the two halves together firmly until you hear a click, indicating that they are securely fastened. Take the screw you set aside earlier and use the screwdriver to tighten it back into place.

Step 6: Test the Key

With the new battery installed, it’s time to test your key. Stand close to your Lexus and press each button on the key to make sure they are working properly. Check if the LED indicator lights up when you press the buttons. If everything functions as expected, congratulations! You have successfully replaced the battery in your Lexus key.
