In this blog post, we will guide you through the process of identifying your key fob, opening it, removing the old battery, replacing it with a new one, and testing the key fob to ensure it’s working properly.

So, let’s get started and learn how to change the battery in your Lexus key fob.
Identifying the Key Fob
When it comes to identifying the key fob for your Lexus, it’s important to know what you’re looking for. A key fob is a small, handheld device that allows you to lock or unlock your car doors, open the trunk, and even start the engine without having to insert a key into the ignition. It typically has buttons for each of these functions, as well as a small LED light that indicates when the fob is in use.
Lexus key fobs may vary in appearance depending on the model and year of your vehicle, so it’s important to consult your owner’s manual or contact your dealership if you’re unsure. However, most Lexus key fobs will have the Lexus logo prominently displayed on the front, along with buttons for locking, unlocking, and possibly opening the trunk.
If you’re still unsure whether you have the correct key fob, you can also compare its appearance to online images of Lexus key fobs for your specific vehicle model and year. This can help ensure that you have the right key fob for performing the necessary maintenance or replacement tasks.
Opening the Key Fob
When the time comes to change the battery in your Lexus key fob, the first step is to open the key fob. This can be done by locating the small release button on the side of the key fob. Press and hold this button to release the key blade.
Once the key blade is removed, you can use a small screwdriver to pry open the key fob. Be careful not to use too much force, as you don’t want to break the key fob casing. Slowly and gently work your way around the edges of the key fob until it pops open.
With the key fob open, you can now easily access the old battery and prepare to replace it with a new one. Remember to handle the small electronic components inside with care to avoid damage.
Removing the Old Battery
When it comes to changing the battery in your Lexus key fob, one important step is to first remove the old battery. This process can vary slightly depending on the model of your key fob, but in general, it’s a relatively simple procedure. Start by identifying the key fob and locating the area where the battery is stored. This may require using a small screwdriver or something similar to carefully pry apart the key fob casing. Once the casing is open, you should be able to see the old battery inside.
Next, carefully remove the old battery from its housing. This may require gently pushing or lifting a small tab or lever to release the battery. Be sure to take note of the orientation of the old battery, as you will need to install the new battery in the same position. Once the old battery is removed, take a moment to clean any dust or debris from inside the key fob casing, as this can affect the performance of the new battery.
After the old battery has been removed and the inside of the key fob casing has been cleaned, you can proceed to replace it with a new battery. Refer to your key fob’s user manual for the specific type of battery required, as well as for any additional instructions on how to properly install the new battery. Once the new battery is securely in place, you can then test the key fob to ensure that it is working correctly with the new battery installed. If everything is working properly, you can then reassemble the key fob casing and resume using your newly refreshed key fob.
Replacing with a New Battery
When it comes time to replace the battery in your Lexus key fob, it is important to follow the proper steps to ensure it is done correctly. First, locate the small notch on the key fob that will allow you to safely remove the battery cover without damaging the unit. Carefully use a small flathead screwdriver to pry open the cover, being mindful not to use excessive force to avoid breaking the plastic.
Once the cover is removed, carefully lift out the old battery using the same screwdriver and dispose of it properly. Take the opportunity to clean any dust or debris from the inside of the key fob using a cloth or compressed air. Next, take the new battery and place it in the designated slot, ensuring it is properly seated and making contact with the terminals.
After the new battery is in place, carefully replace the cover by aligning it properly and pressing down until it snaps into place securely. Test the key fob to make sure it is operating as it should by locking or unlocking your vehicle. If everything is functioning correctly, you have successfully replaced the battery in your Lexus key fob.
Testing the Key Fob
Once you have successfully replaced the old battery with a new one, it’s important to test the key fob to ensure that it is working properly. This can be done by pressing the buttons on the key fob to see if the car responds. If the car does not respond, it may be an indication that the battery has not been installed correctly.
If you find that the key fob is still not working after replacing the battery, you may need to try reprogramming the key fob. This process involves resetting the key fob to ensure that it is synced with your vehicle. You can refer to your vehicle’s manual or contact a professional for assistance with reprogramming the key fob.
It’s important to test the key fob in various scenarios to ensure that it is functioning properly. This includes testing the key fob from different distances and angles to ensure that the signal is being transmitted effectively. By thoroughly testing the key fob, you can ensure that it is working reliably before relying on it for daily use.
