• A small flathead screwdriver or a coin – This will be used to open the key fob.
• A clean cloth – To wipe down the key fob and ensure it remains in good condition.

Step 1: Locate the Key Fob Slot

To replace the battery, you need to access the key fob slot in your Lexus vehicle. The location of this slot may vary depending on the model and year of your Lexus. Generally, you can find the slot in one of the following places:

1. Between the front seats: Look for a small rectangular slot located near the cup holders or the center console. It may be covered by a sliding panel or hidden beneath a trim piece.
2. Inside the center console: Some Lexus models have the key fob slot inside the center console. Open the console lid and check for the slot near the rear portion of the console.

Refer to your vehicle’s owner’s manual for the exact location of the key fob slot in your Lexus.

Step 2: Open the Key Fob

Once you have located the key fob slot, it’s time to open the key fob to access the battery compartment. Follow these steps:

1. Take your small flathead screwdriver or a coin and insert it into the groove or slot on the side of the key fob. Apply gentle pressure to pry open the key fob. Alternatively, some key fobs have a release button that you can press to open the fob.
2. Once the key fob is open, set aside the cover and be careful not to misplace it.

Step 3: Remove the Old Battery

Now that the key fob is open, you will see the battery compartment. To replace the old battery, follow these steps:

1. Take a closer look at the battery compartment. You should see the old battery, typically a round silver disc.
2. Identify the small metal clip or prong that holds the battery in place. Gently lift the clip or prong using your fingernail or the screwdriver, and the old battery should pop out.
3. Remove the old battery from the compartment, making sure to discard it properly according to your local regulations.

Step 4: Insert the New Battery

With the old battery removed, it’s time to insert the new one. Follow these steps:

1. Take the new CR2032 battery and ensure that the positive (+) side is facing up.
2. Place the new battery into the battery compartment, aligning it with the markings or polarity indicators inside.
3. Gently push the battery down until it clicks into place.

Step 5: Close the Key Fob

Now that the new battery is securely in place, it’s time to close the key fob. Follow these steps:

1. Take the key fob cover that you set aside earlier.
2. Align the cover with the key fob and ensure that it snaps into place. You may need to apply slight pressure to ensure a secure fit.
3. Give the key fob a gentle squeeze to confirm that it is closed tightly.

Step 6: Test the Key Fob

Before considering the battery replacement process complete, it’s important to test the key fob to ensure it is working correctly. Follow these steps:

1. Stand near your Lexus vehicle and press any button on the key fob.
2. Check if the corresponding action, such as unlocking the doors or opening the trunk, occurs.
3. If the key fob functions as expected, congratulations! You have successfully replaced the battery. If not, double-check the battery orientation and close the key fob tightly before retrying.
