Is your Toyota Prius key fob acting up? Maybe it’s beeping at you after you turn off the engine, or the range seems significantly reduced. You might even notice the security key icon flashing on your dashboard. These are all tell-tale signs that your key fob battery is running low and needs replacing. Since the Toyota Prius relies on an electronic key system without a traditional mechanical key start, a dead key fob battery can be a real inconvenience. Don’t worry, replacing the battery in your Toyota 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 to get your key fob working like new again.
Knowing when to replace your Prius key fob battery can save you from unexpected headaches. Typically, these batteries last for 3 to 5 years, depending on usage. Original batteries are often Panasonic brand, as seen in models from 2008 and 2009. Proactive maintenance is key, and this guide will empower you to handle this minor repair yourself.
Tools You’ll Need
Before you begin, gather these simple tools:
- Precision Philips Head Screwdriver: A #0 size is ideal for the small screws in your key fob.
- Thin Flat-head Screwdriver or Paperclip: This will help with prying open the battery compartment cover.
Parts You’ll Need
- CR2032 Battery: This is the standard 3V coin cell battery required for your Toyota Prius key fob. You can find these at most drugstores, supermarkets, and online retailers.
Step-by-Step Battery Replacement Guide
Follow these easy steps to replace your Toyota Prius key fob battery:
Step 1: Remove the Emergency Key
With the key fob buttons facing upwards, locate the small spring-loaded holder at the top. Slide this holder to the left (as indicated by the red arrow in the image above) while simultaneously pulling the emergency key upwards and out (as shown by the blue arrow). Set the emergency key aside.
Step 2: Open the Key Fob Casing
Flip the key fob over so the buttons are facing downwards. Locate the same spring-loaded holder you used in Step 1. This time, slide the holder to the right (red arrow). While holding it in this position, gently push the back panel upwards (blue arrow). The back panel should slide off relatively easily, revealing the internal components of the key fob. If you encounter slight resistance, try using a rubber glove to improve your grip on the fob for better leverage.
Step 3: Access the Battery Compartment
With the back panel removed, you will now see the battery cover plate secured by four small screws. Using your Philips #0 screwdriver, carefully remove these four screws (circled in red in the image above). Once the screws are removed, take your paperclip or thin flat-head screwdriver and gently pry up the battery cover plate. The blue arrow in the image indicates a convenient point from where you can pry.
Step 4: Replace the Old Battery
With the battery cover plate removed, you can now access the CR2032 battery. Take note of the battery orientation before removing it. The positive (+) side of the battery should be facing upwards, towards the cover panel. Carefully remove the old battery and insert the new CR2032 battery in the same orientation, ensuring the positive (+) side is facing up.
Step 5: Reassemble the Key Fob
Assembly is simply the reverse of the disassembly process.
- Place the battery cover plate back into position and secure it with the four Philips head screws.
- Slide the back panel back onto the key fob until it clicks into place.
- Finally, re-insert the emergency key into the key fob until it locks securely.
