Is your 2007 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 task you can easily do yourself in just a few minutes. This guide, brought to you by the auto experts at keyfobx.com, will walk you through each step to replace your Prius key fob battery, ensuring you’re back on the road with a fully functional remote in no time.
Tools You’ll Need
Before you begin, gather these simple tools:
- Small Phillips Head Screwdriver: A #0 precision screwdriver is ideal for the tiny screws in your key fob.
- Thin Flat-head Screwdriver or Paperclip: This will help with prying open the battery compartment.
Parts You’ll Need
- CR2032 Battery: You’ll need one CR2032 3V lithium battery. This is a common size and readily available at most drugstores, supermarkets, and online retailers.
Step-by-Step Battery Replacement Guide
Let’s get started with replacing your 2007 Toyota Prius key fob battery:
Step 1: Remove the Emergency Key
With the buttons facing upwards, locate the small spring-loaded release on the side of your key fob. Slide this release to the left (indicated by RED in the image above) and simultaneously pull the emergency key upwards and out of the fob (indicated by BLUE). Set the key aside.
Step 2: Open the Key Fob Casing
Flip the key fob over so the buttons are facing down. Locate the same spring-loaded holder you used in Step 1. This time, slide the holder to the right (indicated by RED). While holding it to the right, gently push the back panel upwards (indicated by BLUE). The back panel should slide off, revealing the inside of the key fob. If you’re having trouble getting a grip, try using a rubber glove for better traction.
Step 3: Access the Battery Compartment
You’ll now see the internal components of the key fob and a small battery cover plate secured by four screws. Using your Phillips #0 screwdriver, carefully remove the four screws circled in RED in the image. Once the screws are removed, use your paperclip or 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 and pry.
Step 4: Replace the Old Battery
With the battery cover removed, you can now access the CR2032 battery. Take note of the battery orientation 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 Your Key Fob
Now that you’ve replaced the battery, reassembly is simply the reverse of the disassembly process:
- Place the battery cover plate back over the battery compartment.
- Reinstall the four small Phillips head screws to secure the cover plate.
- Slide the back panel of the key fob back into place until it clicks shut.
- Finally, slide the emergency key back into the key fob until it locks securely.
You’re All Set!
That’s all there is to it! You’ve successfully replaced the battery in your 2007 Toyota Prius key fob. Your remote should now be working perfectly again. Replacing your key fob battery is a simple maintenance task that can save you time and money compared to visiting a dealership. By following these easy steps, you can ensure your key fob is always ready to unlock your Prius and get you on your way.
