The key fob is an important component of your RAV4, as it allows you to unlock and lock the doors, as well as start the engine with the push of a button. Over time, the battery in the key fob can lose its charge, and you’ll need to replace it to keep your key working properly.
The process of replacing the battery in a RAV4 key is relatively simple and can be done at home with a few basic tools. First, you’ll need to determine the type of key fob you have.

It’s important to note that the exact location of the key cover slot may vary slightly depending on the specific model and year of your RAV4 key fob.
Once you have located the key cover slot, you are ready to move on to the next step of the battery replacement process.
Insert a Small Tool into the Slot
When it comes time to replace the battery in your RAV4 key fob, the first step is to locate the small slot on the side of the key. This slot is specifically designed for easy battery replacement and can be easily identified by its size and shape.
To begin, find a small tool that is thin and sturdy enough to fit into the slot. Examples of suitable tools include a small flathead screwdriver or a paperclip that has been straightened out.
Once you have your tool ready, gently insert it into the slot and apply some pressure to release the cover. You may need to wiggle the tool slightly to help loosen the cover. Be careful not to apply too much force or you risk damaging the keyless entry fob.
Opening the Key Fob
After successfully releasing the cover, you can then proceed to open the key fob. Place your fingers on either side of the fob and carefully pry it open. Take your time and be gentle to avoid any damage.
Inside the key fob, you will find the battery compartment. At this point, it’s a good idea to take note of the type of battery your RAV4 key fob requires. This information can usually be found on the back of the battery or in the owner’s manual.
