When it’s time to change the battery in your Lexus key fob, the first step is to identify the key fob model that you have. This will ensure that you purchase the correct replacement battery for your specific key fob model. Each Lexus key fob model may have a different battery type and size, so it’s important to match the replacement battery with the correct model.
One way to identify the key fob model is to check the owner’s manual for your Lexus vehicle. The manual typically contains detailed information about the key fob, including the model number and type of battery needed. If you don’t have the owner’s manual, you can also look for the model number and battery type on the key fob itself. The model number may be printed on the back of the key fob, or you may need to open the key fob case to locate the information.
Another option is to contact your local Lexus dealership for assistance. They can help you identify the key fob model and provide you with the correct replacement battery information. With the key fob model identified, you can then proceed to gather the necessary tools and replacement battery for the next steps in changing the battery in your Lexus key fob.
Gathering the Necessary Tools
Before you start the process of changing the battery in your Lexus key fob, it’s important to ensure that you have all the necessary tools on hand. One essential tool you will need is a small flathead screwdriver, which will be used to open the key fob case. Additionally, a new CR2032 battery will be required to replace the old one. It’s important to use a high-quality battery to ensure optimal performance of your key fob. Finally, it’s a good idea to have a pair of small tweezers on hand, as they can be helpful when removing the old battery from the key fob.
Opening the Key Fob Case
When it comes to changing the battery in your Lexus key fob, one of the first steps is to open the key fob case. In order to do this, you will need to gather the necessary tools such as a small screwdriver or prying tool to help you open the case without damaging it. It’s important to be careful and gentle when prying open the case to avoid breaking any of the components inside.
Once you have your tools ready, you can begin the process of opening the key fob case. Start by locating the groove or seam around the edge of the key fob where the two halves of the case meet. Insert the screwdriver or prying tool into this groove and gently apply pressure to pry open the case. Work your way around the entire edge of the case, being mindful not to force the case open too quickly or with too much pressure.
As you gradually open the case, you may hear some snapping or clicking sounds as the plastic tabs inside the case release. This is normal, but it’s still important to proceed with caution to avoid any damage. Once you have successfully opened the case, you can proceed with the next steps of replacing the old battery and assembling the key fob.

Before you start the process of replacing the old battery in your Lexus key fob, it’s important to identify the specific model of your key fob. The method for replacing the battery may vary depending on the model, so it’s crucial to ensure you have the correct instructions for your particular key fob.
Gathering the Necessary Tools
Once you have identified the model of your Lexus key fob, gather the necessary tools for replacing the old battery. You will need a small flat-head screwdriver to open the key fob case, as well as a new battery of the appropriate size for your key fob model. It’s also a good idea to have a clean cloth on hand to wipe the inside of the key fob if needed.
Opening the Key Fob Case
After gathering the necessary tools, carefully use the small flat-head screwdriver to pry open the key fob case. Be gentle and take your time to avoid damaging the case or the internal components of the key fob. Once the case is open, you will have access to the old battery that needs to be replaced.
Assembling the Key Fob
Now that the old battery has been replaced, it’s time to put the key fob back together. First, carefully place the key fob cover over the battery compartment, making sure it aligns properly with the rest of the key fob. Then, gently press down on the edges of the cover to snap it back into place.
Next, if your key fob has a key ring attached, reattach it to the key fob. Make sure it is secured tightly to avoid any accidental drops. Once the key ring is in place, give the key fob a quick test to ensure that the buttons are working properly and the new battery is functioning as it should.
Finally, before using the key fob, ensure that all components are securely in place and that there are no loose parts. Once you have confirmed everything is in order, your key fob is now ready to be used!
