Is your 2007 Toyota Prius key fob acting up? Experiencing issues like decreased range, beeping after turning off your car, or a flashing key icon on your dashboard? These are common signs that your key fob battery is running low and needs replacing. Don’t worry, replacing the battery in your 07 Prius key fob is a straightforward task you can easily do yourself, saving you time and money. This guide will walk you through each step to get your key fob working like new again.
Before you begin, please remember to consult your vehicle’s owner’s manual for specific safety information and warnings.
Tools You’ll Need:
- Precision Philips head screwdriver (#0 recommended)
- Small flat-head screwdriver or a paperclip
Parts Required:
- One CR2032 battery (the standard battery for most Prius key fobs)
Step-by-Step Battery Replacement Guide:
- Remove the Emergency Key: Locate the small release lever or button on your key fob. With the buttons facing upwards, slide the spring-loaded holder to the left and simultaneously pull the emergency key straight up and out. This key is a separate component and needs to be removed first to access the key fob casing.
- Open the Key Fob Casing: Turn the key fob over so the buttons are facing down. Find the spring-loaded holder again and this time, slide it to the right. While holding it in this position, gently push the back panel of the key fob upwards. It should slide off, revealing the internal components. If you’re having trouble sliding the back panel, try using a rubber glove for better grip.
- Access the Battery: You’ll now see the internal circuit board and a battery cover plate secured by four small screws. Using your Philips #0 screwdriver, 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.
-
Replace the Old Battery: With the battery cover removed, you can now access the CR2032 battery. Take note of the battery orientation – 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.
-
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 screws you removed earlier. Slide the back panel of the key fob back into place until it clicks securely. Finally, slide the emergency key back into the key fob until it locks.
Once reassembled, test your 07 Prius key fob to ensure it’s working correctly. The increased range and absence of warning beeps should confirm a successful battery replacement. Replacing your 07 Prius Key Fob Battery is a quick and easy way to maintain your vehicle and avoid potential key fob issues.
