Step-by-Step Guide to Replacing Your Prius Key Fob Battery
Follow these straightforward steps to replace your Toyota Prius key fob battery:
Step 1: Remove the Emergency Key
Locate the small release button or lever on your key fob. It’s usually a small, spring-loaded slider. While sliding this release, pull the mechanical emergency key straight out of the fob. Set the key aside in a safe place.
Step 2: Open the Key Fob Casing
With the buttons on your key fob facing down, locate the small seam on the side where you just removed the emergency key. Slide the same spring-loaded holder again, but this time in the opposite direction from when you removed the key. While sliding, gently push the back panel of the key fob upwards. It should slide and detach from the main body of the fob. If you have trouble gripping the fob, try using a rubber glove for better traction.
Step 3: Access and Replace the Battery
Now you will see the internal components of the key fob. Locate the small battery cover plate, which is typically held in place by four small screws. Using your #0 Phillips head screwdriver, carefully remove these four screws. Once the screws are removed, use a paperclip or a thin flathead screwdriver to gently pry up the battery cover plate. You can insert the paperclip or screwdriver into the small notch indicated in the image below to help lift the plate.
Underneath the cover plate, you’ll find the CR2032 battery for your toyota prius key fob. Note the orientation of the battery – the positive (+) side should be facing upwards, towards the cover plate you just removed. Carefully remove the old battery. You can use your fingertip or the small flathead screwdriver to gently pry it out. Install the new CR2032 battery, ensuring the positive (+) side is facing up.
Step 4: Reassemble the Key Fob
With the new battery in place, reassemble the key fob in reverse order. Place the battery cover plate back onto the key fob and secure it with the four small screws. Ensure the screws are snug but not overtightened. Finally, slide the back panel of the key fob back into place until it clicks securely. Reinsert the emergency key until it clicks into its locked position.
You’re Done!
