Step-by-Step 2008 Prius Key Fob Battery Replacement Guide
Follow these easy steps to replace your 2008 Prius key fob battery:
Step 1: Remove the Mechanical Key
With the buttons on your key fob facing upwards, locate the small, spring-loaded holder at the top. Slide this holder to the left (usually indicated by an arrow or release button). While holding it in the left position, pull the mechanical key upwards and out of the fob. This key is a backup and is removed to access the fob casing.
Step 2: Open the Key Fob Casing
Flip the key fob over so the buttons are facing down. Again, locate the spring-loaded holder, this time at the bottom of the fob. Slide this holder to the right. While holding it to the right, gently push the back panel of the key fob upwards. This back panel should slide off, revealing the inside of the key fob. If you are having trouble sliding the back panel, try using a rubber glove for a better grip.
Step 3: Access the Battery
With the back panel removed, you will see the battery compartment. There is a small cover plate secured by four screws. Use your Philips #0 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 prying point is usually indicated by a small notch or arrow on the side of the plate.
Step 4: Replace the Old Battery
Now you can access the old CR2032 battery. Take note of the orientation of the battery before removing it; 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, ensuring the positive (+) side is facing up.
Step 5: Reassemble the Key Fob
Assembly is simply the reverse of the disassembly process. Carefully place the battery cover plate back into position and secure it with the four Philips screws. Slide the back panel of the key fob back into place until it clicks or feels secure. Finally, slide the mechanical key back into the top of the key fob until it locks into position.
Conclusion
Congratulations! You have successfully replaced the battery in your 2008 Prius key fob. This simple maintenance task can save you time and money compared to going to a dealership. With a fresh CR2032 battery, your key fob should now be functioning perfectly, giving you reliable remote access to your 2008 Toyota Prius. Remember to dispose of the old battery responsibly at a designated battery recycling location.
