Step-by-Step Guide to Replacing Your 2009 Prius Key Fob Battery
Follow these easy steps to replace your key fob battery:
Step 1: Remove the Mechanical Key
Begin by removing the mechanical key from the key fob. Locate the small, spring-loaded holder on the key fob, positioned near where the key ring would attach. With the buttons facing upwards, slide this holder to the left (as indicated by the red arrow in the image above) and simultaneously pull the mechanical key upwards and out of the fob (as shown by the blue arrow). Set the mechanical key aside for now.
Step 2: Open the Key Fob Casing
Next, you’ll need to open the key fob casing to access the battery. Turn the key fob over so that the buttons are facing downwards. Locate the same spring-loaded holder you used to remove the mechanical key. This time, slide the holder to the right (indicated by the red arrow). While holding it in this position, push the back panel upwards (as shown by the blue arrow). The back panel should slide off relatively easily. If you encounter resistance, try using a rubber glove to improve your grip on the fob for better leverage.
Step 3: Access and Replace the Battery
With the back panel removed, you’ll now see the battery compartment. Using your Phillips #0 screwdriver, carefully remove the four small screws circled in red in the image. Once the screws are removed, you can use a paperclip or a thin flat-head screwdriver to gently pry up the battery cover plate. The blue arrow in the image indicates a good spot to insert your tool for prying. Underneath the cover plate, you’ll find the CR2032 battery. Carefully remove the old battery and replace it with a new CR2032 battery, ensuring the positive (+) side is facing upwards, towards the cover panel.
Step 4: Reassemble the Key Fob
Reassembling the key fob is simply the reverse of the disassembly process. Place the battery cover plate back over the battery, ensuring it’s correctly aligned. Replace and tighten the four small Phillips head screws. Slide the back panel of the key fob back into place until it clicks securely. Finally, slide the mechanical key back into the key fob until it locks into position.
Conclusion
Congratulations! You’ve successfully replaced the battery in your 2009 Toyota Prius key fob. This simple maintenance task can save you time and money compared to visiting a dealership. By following these steps, you can ensure your key fob remains reliable, giving you continued access and convenience with your Prius. Remember to keep an eye out for those telltale signs of a low battery in the future, and you’ll be prepared to handle it yourself!
