Tools and Parts You’ll Need
Before you begin, gather these simple tools and parts:

Step-by-Step 2009 Prius Key Fob Battery Replacement
Follow these easy steps to replace your 2009 Prius key fob battery:
Step 1: Remove the Physical Key
With the buttons on your key fob facing upwards, locate the small spring-loaded holder. Slide this holder to the left while simultaneously pulling the physical key upwards and out of the fob. This key is a backup and is usually not needed for battery replacement, but removing it first makes the next steps easier.

Step 2: Open the Key Fob Casing
Flip the key fob so the buttons are facing down. Locate the spring-loaded holder again and this time, slide it to the right. While holding it to the right, push the back panel of the key fob upwards. It should slide off relatively easily, exposing the inside of the key fob. If you are having trouble sliding the back panel, try using a rubber glove to improve your grip.

Step 3: Access the Battery
You will now see the internal components and the battery cover plate secured by four small screws. Use your #0 Phillips head screwdriver to carefully remove these four screws. Once the screws are removed, use a paperclip or a thin flat-head screwdriver to gently pry up the battery cover plate. The designated pry point is usually indicated by a small notch or arrow.

Step 4: Replace the Battery
With the battery cover removed, you can now access the old CR2032 battery. Take note of the battery’s orientation – the positive (+) side should be facing upwards, towards the cover panel. Remove the old battery and insert the new CR2032 battery in the same orientation.
