Is your Toyota Prius key fob starting to act up? Experiencing issues like reduced range, beeping after turning off the engine, 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 Prius key fob is a simple task you can easily do yourself in just a few minutes. This guide will walk you through each step, ensuring you get your key fob back in perfect working order.
Tools and Parts You’ll Need
Before you begin, gather these simple tools and the replacement battery:
- Small Phillips head screwdriver: A #0 precision screwdriver is ideal.
- Thin flat-head screwdriver or paperclip: For prying open the battery cover.
- CR2032 Battery: This is the standard battery type for most Prius key fobs. You can find these at most drugstores, supermarkets, or online retailers.
Step-by-Step Battery Replacement Guide
Follow these easy steps to replace your Prius key fob battery:
Step 1: Remove the Key Blade
Locate the small release button or lever on the side of your key fob. With the buttons facing upwards, slide the spring-loaded holder to the left (as indicated by RED in the image). While holding it in this position, pull the emergency key blade straight up and out (BLUE). Set the key blade aside.
Step 2: Open the Key Fob Casing
Now, flip the key fob over so the buttons are facing down. Locate the small rectangular panel on the back of the fob. Slide the spring-loaded holder to the right (RED in the image). While sliding, gently push the back panel upwards (BLUE). It should slide off relatively easily, revealing the inside of the key fob. If you encounter resistance, try using a rubber glove for better grip.
Step 3: Access the Battery
With the back cover removed, you’ll see the circuit board and battery compartment. Identify the four small screws (circled in RED in the image) securing the battery cover plate. Use your #0 Phillips head screwdriver to carefully remove these screws and set them aside in a safe place. 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 pry from.
Step 4: Replace the Old Battery
Remove the old CR2032 battery. Note the orientation of the battery; the positive (+) side should be facing upwards, towards the cover panel. Insert the new CR2032 battery in the same orientation, ensuring the positive (+) side is facing up.
Step 5: Reassemble the Key Fob
Now, simply reverse the disassembly process to reassemble your key fob. 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, reinsert the emergency key blade until it locks securely.
You’re All Set!
Congratulations, you’ve successfully replaced the battery in your Toyota Prius key fob! Your key fob should now be working perfectly. If you continue to experience issues, double-check that you’ve installed the battery correctly and that it is a fresh CR2032 battery. Replacing your Prius key fob battery is a straightforward maintenance task that can save you time and money compared to visiting a dealership. Enjoy the renewed convenience of your keyless entry!
