If you’re driving a 2004 Toyota Sienna, chances are you rely on your key fob to lock, unlock, and even start your minivan. But what happens when your key fob starts acting up? A dead battery is often the culprit. Luckily, replacing the key fob battery in a 2004 Toyota Sienna is a simple task that you can do yourself in minutes.
Let’s walk through everything you need to know about replacing your 2004 Toyota Sienna key fob battery.
Recognizing a Dying Key Fob Battery
Before we jump into the replacement process, how can you tell if your key fob battery is actually the problem? Here are a few telltale signs:
- Decreased Range: You find yourself standing closer and closer to your Sienna to get the key fob to work.
- Intermittent Functioning: Sometimes the key fob works perfectly, other times it seems completely dead.
- No Response: The key fob doesn’t respond at all, no matter how many times you press the buttons.
If any of these scenarios sound familiar, a dead battery is the likely culprit.
What You’ll Need for the Replacement
You only need a couple of simple tools to replace the battery:
- A small flat-head screwdriver (or a similar tool for prying)
- A new CR2032 battery (This is the standard battery for most Toyota key fobs)
You can find CR2032 batteries at most drugstores, electronics stores, and even auto parts stores.

Replacing the Battery: A Step-by-Step Guide
Now for the easy part – the actual replacement:
- Open the Key Fob: Locate the small seam or groove on the side of your key fob. Carefully insert the flat-head screwdriver into the groove and gently pry the two halves of the key fob apart.
- Access the Battery: Inside the key fob, you’ll see the CR2032 battery nestled in a compartment. Use your fingernail or the screwdriver to gently lift the battery out.
- Install the New Battery: Place the new CR2032 battery into the compartment, ensuring that the positive (+) side faces up.
- Reassemble the Key Fob: Align the two halves of the key fob and press them firmly together until you hear a snap, indicating they’re securely closed.
That’s it! You’ve successfully replaced your 2004 Toyota Sienna key fob battery.
Testing Your New Battery
After putting everything back together, test the key fob to ensure the new battery is working properly:
- Lock and unlock your Sienna using the key fob buttons.
- Try starting the engine with the key fob in the ignition (if your Sienna has a push-button start).
If everything works as expected, you’re good to go!
Key Fob Battery Replacement Tips
