If you’re experiencing issues with your 2004 Toyota Prius key fob, a dead battery might be the culprit. Thankfully, replacing the battery is a quick and easy fix you can do yourself, saving you time and money. This guide will walk you through the process step-by-step, empowering you to get back on the road with a fully functioning key fob in no time.
How to Tell if Your Key Fob Battery Needs Replacing
Before you start digging for tools, it’s helpful to confirm if the battery is truly the issue. Here are some telltale signs that your 2004 Toyota Prius key fob needs a new battery:
- Decreased Range: You find yourself having to stand closer to your car for the key fob to unlock the doors or activate the alarm.
- Intermittent Functionality: The key fob works sometimes, but not always. This inconsistency points to a weak battery that’s on its last legs.
- No Response: The key fob doesn’t respond at all when you press the buttons. This lack of response usually means the battery is completely drained.
What You’ll Need for a 2004 Toyota Prius Key Fob Battery Replacement
Gathering the necessary tools beforehand will make the replacement process smoother. Here’s what you’ll need:
- Replacement Battery: A CR2032 battery. This common lithium coin battery is readily available at most electronics and auto parts stores.
- Small Flathead Screwdriver: This tool will be used to pry open the key fob casing.
Replacing the Battery in a Toyota Prius Key Fob: A Step-by-Step Guide
Now, let’s dive into the battery replacement process itself:
- Open the Key Fob: Locate the small groove on the side of your key fob. Carefully insert the flathead screwdriver into the groove and gently pry open the casing. Be mindful not to apply excessive force, as this could damage the key fob.
- Identify the Battery: Inside the casing, you’ll see the round, flat CR2032 battery. Note its position within the key fob.
- Remove the Old Battery: Gently pry out the old battery from its slot using your flathead screwdriver. Avoid touching the battery’s flat surfaces to prevent transferring oils from your fingers, which can impact its performance.
- Insert the New Battery: Place the new CR2032 battery into the slot, ensuring the positive (+) side faces up, just like the old battery.
- Reassemble the Key Fob: Carefully align the two halves of the key fob casing and press them together firmly until you hear a click. This click indicates that the casing is securely closed.
Testing Your New Key Fob Battery
After replacing the battery, it’s essential to test if it’s working correctly. Try locking and unlocking your car doors and using the other key fob functions. If everything operates as expected, congratulations! You’ve successfully replaced your 2004 Toyota Prius key fob battery.

While a dead battery is the most common culprit for key fob issues, other problems could be at play. If you’re still experiencing problems after replacing the battery, your key fob might need to be reprogrammed or repaired. In these cases, consulting a qualified automotive locksmith or your Toyota dealership is recommended.
