Opening the Key Fob
Before you begin opening the key fob on your Lexus RX 350, you will need to gather the necessary tools and supplies. This will include a small screwdriver or prying tool, as well as a replacement battery for the key fob. It’s important to have everything prepared before you start the process to ensure a smooth and efficient battery replacement.
Once you have the tools and supplies ready, you can proceed with opening the key fob. Start by using the small screwdriver or prying tool to gently pry open the fob along the seam. Be careful not to use too much force, as you don’t want to damage the key fob. Work your way around the entire fob to release the clips holding it together. Once the fob is open, you can carefully set aside the front and back pieces.
With the key fob open, you will have access to the internal components, including the old battery. Take your time to familiarize yourself with the layout and design of the interior to ensure that you can easily replace the battery. This step is crucial in successfully completing the battery replacement process for your Lexus RX 350 key fob.
Removing the Old Battery
When it comes to changing the battery in your Lexus RX 350 key fob, you will need to carefully remove the old battery to make way for the new one. Start by gathering the necessary tools and supplies such as a small screwdriver or a flat tool that can help pry open the key fob. Once you have everything you need, you can proceed with the process of removing the old battery.
First, carefully examine the key fob and identify the seam where the two halves of the fob meet. Use the small screwdriver or flat tool to carefully pry open the key fob along this seam. Be gentle to avoid damaging the fob or the internal components. Once you have successfully opened the fob, you will be able to access the old battery, which is typically held in place by a small clip or a cover.
Next, use the screwdriver or tool to carefully remove the old battery from its housing. Pay attention to the orientation of the battery so that you can easily insert the new one in the same way. Take note of any clips or covers that need to be manipulated in order to release the old battery. Once the old battery is removed, you can proceed with inserting the new battery and closing the key fob, which are the next steps in the process.
Inserting the New Battery
After successfully removing the old battery from your Lexus RX 350 key fob, it’s time to insert the new one. Make sure the replacement battery is the correct type and size for your key fob. It should be a 3V CR2032 lithium coin cell battery.
First, take the new battery and carefully place it into the compartment with the positive side facing downwards. Press the battery down gently until it is secure in place. Double-check that the battery is properly seated and will not fall out when the key fob is closed.
Once the new battery is in place, it’s time to put the key fob back together. Follow the steps in reverse order, beginning by reattaching the key fob cover. Make sure the cover is aligned correctly and snaps back into place. Test the functionality of the key fob to ensure that the new battery is working properly.
