Is your 2007 Toyota Prius key fob starting to act up? Perhaps you’ve noticed the car beeping after you turn it off, a decrease in remote range, or the key symbol flashing on your dashboard. These are common signs that your 2007 Toyota Prius Key Fob Battery is getting weak and needs replacing. Don’t worry, this is a straightforward DIY task that you can easily accomplish at home with a few simple tools. Since the Prius relies on its electronic key system to start, replacing the battery promptly is crucial to avoid being stranded.
Just like the original battery in your 2007 Prius key fob, replacements are often Panasonic CR2032 batteries, known for their 3-5 year lifespan. This guide will walk you through replacing your 2007 Toyota Prius key fob battery quickly and efficiently.
Tools and Parts You’ll Need
Before you begin, gather these simple tools and the replacement battery:
- Precision Phillips Head Screwdriver (#0): Essential for removing the small screws in the key fob. A set of precision screwdrivers ensures you have the right size.
- Thin Flat-head Screwdriver or Paperclip: Used for gently prying open the key fob and removing the battery cover.
- CR2032 Battery: This is the specific type of battery required for your 2007 Toyota Prius key fob. You can find these at most drugstores, supermarkets, and online retailers.
Step-by-Step Battery Replacement Guide
Follow these steps to replace the battery in your 2007 Toyota Prius key fob:
Step 1: Remove the Mechanical Key
With the buttons facing upwards, locate the small spring-loaded lever on the side of your 2007 Toyota Prius key fob. Slide this lever to the left (indicated in RED in the image). While holding the lever to the left, pull the mechanical key upwards and out of the fob (indicated in BLUE). Set the mechanical key aside.
Step 2: Open the Key Fob Casing
Turn the key fob over so the buttons are facing down. Locate the spring-loaded panel that you just released by removing the mechanical key. Slide this panel to the right (RED) and simultaneously push the back panel upwards (BLUE). This back panel should slide off relatively easily, exposing the battery compartment. If you are having trouble getting a grip, try using a rubber glove for better traction.
Step 3: Access the Battery
Using your Phillips #0 screwdriver, remove the four small screws (circled in RED) that secure the battery cover plate. Once the screws are removed, use a 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 for prying. Be careful not to scratch the plastic casing.
Step 4: Replace the Old Battery
With the battery cover removed, you can now access the CR2032 battery. Take note of the orientation of the old battery – the positive (+) side should be facing upwards, towards the cover panel. Remove the old battery and replace it with a new CR2032 battery, ensuring the positive (+) side is facing the correct direction.
Step 5: Reassemble the Key Fob
Reassembly is simply the reverse of the disassembly process. Place the battery cover plate back into position and secure it with the four small screws. Slide the back panel back onto the key fob until it clicks into place. Finally, slide the mechanical key back into its slot until it locks.
You’re Done!
You have now successfully replaced the battery in your 2007 Toyota Prius key fob. Test the fob to ensure it is working correctly, and those low battery warnings should be gone. Replacing your 2007 Toyota Prius key fob battery is a quick and cost-effective way to maintain your vehicle’s keyless entry system and avoid any inconvenience caused by a dead battery.
