Is your 2009 Toyota Prius key fob starting to act up? Experiencing decreased range, warning beeps after turning off your car, or a flashing key icon on your dashboard? These are common signs that your key fob battery is getting weak and needs replacing. Don’t worry, this is a straightforward maintenance task you can easily handle yourself. This guide will walk you through replacing the battery in your 2009 Prius key fob quickly and efficiently, ensuring you’re not caught off guard by a dead key fob.
Before you begin, please remember to consult your vehicle’s owner’s manual for any specific warnings and safety information.
Tools You’ll Need:
- Small Phillips head screwdriver (size #0 is ideal)
- Thin flat-head screwdriver or a paperclip
Parts Required:
- CR2032 Battery – This is the standard battery for the 2009 Toyota Prius key fob.
Step-by-Step Battery Replacement Guide:
Let’s get started with the battery replacement process. Follow these simple steps to revitalize your 2009 Prius key fob.
Step 1: Remove the Mechanical Key
With the button side of your key fob facing upwards, locate the small spring-loaded lever. Slide this lever 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; you won’t need it for the battery replacement itself, but it’s good to keep it in a safe place.
Step 2: Open the Key Fob Casing
Flip the key fob so the buttons are facing downwards. Again, you’ll see a spring-loaded holder. This time, slide it to the right (red arrow). While holding it in this position, push the back panel upwards (blue arrow). The back panel should slide off relatively easily, revealing the battery compartment. If you encounter slight resistance, using a rubber glove can provide extra grip to help slide the panel open.
Step 3: Access the Battery
With the back cover removed, you will now see the battery compartment secured by a small plate and four screws. Using your Phillips #0 screwdriver, carefully remove the four screws circled in red in the image. Once the screws are removed, 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. Be gentle to avoid damaging the plastic casing.
Step 4: Replace the Battery
Now you can access the old CR2032 battery. Remove the old battery and take note of its orientation. It’s crucial to install the new CR2032 battery in the same way, with the positive (+) side facing upwards, towards the cover panel. Once the new battery is correctly placed, assembly is simply the reverse of the disassembly process.
Step 5: Reassemble the Key Fob
Carefully place the battery cover plate back into position and secure it with the four screws you removed earlier. Ensure they are snug but not overtightened. Next, slide the back panel back onto the key fob until it clicks into place. Finally, re-insert the mechanical key into the key fob until it locks securely.
You’re Done!
That’s all there is to it! You’ve successfully replaced the battery in your 2009 Toyota Prius key fob. Test the fob to ensure it’s working correctly – your Prius should now respond to the lock, unlock, and panic buttons without issue. Replacing your key fob battery proactively when you notice the initial warning signs can save you from potential inconvenience and ensure you always have reliable access to your vehicle. Typically, these batteries last for 3-5 years, so periodic replacement is a normal part of Prius ownership.
