When this happens, you will need to replace the battery to ensure that your key fob continues to function properly. In this guide, we will walk you through the steps to change the battery in a Lexus RX350 key fob.

Step 1: Gather the necessary tools

Before you begin, make sure you have the following tools ready:

  • Replacement battery (CR2032 type)
  • Small Phillips head screwdriver

Having these tools on hand will ensure a smooth and hassle-free battery replacement process.

Step 2: Locate the battery compartment

To change the battery in your Lexus RX350 key fob, you first need to locate the battery compartment. Look for a small indentation or groove on the side of the key fob. This is where the battery compartment is usually located.

Step 2.1: Remove the key from the key fob

Before accessing the battery compartment, you need to remove the key from the key fob. Look for a release button or switch on the key fob that allows you to separate the key. Once the key is removed, you can proceed to the next step.

Step 3: Open the battery compartment

Using a small Phillips head screwdriver, gently insert the tip into the groove or slot on the side of the key fob. Apply slight pressure and twist the screwdriver to open the battery compartment. Be careful not to apply too much force or you may damage the key fob.

Step 3.1: Remove the old battery

Inside the battery compartment, you will find the old battery. Carefully lift the old battery out of the compartment using your fingers, a small screwdriver, or a pair of tweezers. Take note of the battery’s orientation as you will need to insert the new battery in the same position.

Step 4: Insert the new battery

Take the new CR2032 battery and ensure that the positive (+) side is facing up. Align the new battery with the markings or indicators inside the battery compartment and gently place it in the designated space. Press down on the battery to make sure it is securely in place.

Step 5: Close the battery compartment

Once you have inserted the new battery, it’s time to close the battery compartment. Align the cover or lid of the compartment with the key fob and press firmly until you hear a click or feel it snap back into place.

Step 5.1: Reattach the key to the key fob

Now that the battery compartment is closed, you can reattach the key to the key fob. Line up the key with the designated slot on the key fob and push it back into place. Make sure it is securely attached before moving on to the next step.

Step 6: Test the key fob

To ensure that the new battery is working properly, test the key fob by pressing the lock and unlock buttons. If the key fob successfully locks and unlocks your Lexus RX350, then the battery replacement was successful.

Step 7: Properly dispose of the old battery

Now that you have replaced the battery in your Lexus RX350 key fob, it’s important to dispose of the old battery properly. Do not throw it in the regular trash as batteries can be harmful to the environment. Instead, take it to a designated recycling center or drop-off point for safe disposal.

Step 8: Additional tips

To ensure the longevity of your key fob battery, consider the following tips:

  • Avoid exposing the key fob to extreme temperatures as it can affect the battery life.
  • Keep the key fob away from water or liquids to prevent damage to the internal components.
  • If your key fob is not working even after replacing the battery, consult your Lexus dealership for further assistance.

By following these steps and tips, you can easily change the battery in your Lexus RX350 key fob and continue to enjoy the convenience it provides.
