Is your 2007 Toyota Camry smart key fob not working as reliably as it used to? You might be facing a dead battery. Don’t worry, replacing the battery in your Toyota Camry key fob is a simple task you can easily do yourself at home. This guide will walk you through each step, saving you time and money compared to dealership service.
Before we begin, it’s worth noting that while this guide is specifically for a 2007 Toyota Camry, the process is likely very similar for other Toyota models and years. However, key fob designs and battery types can vary, so always double-check if you’re working with a different vehicle.
You’ll know it’s time for a battery replacement when you start experiencing symptoms like:
- Reduced Range: You need to be closer to your Camry for the key fob to lock or unlock the doors.
- Inconsistent Operation: Sometimes the buttons work, and sometimes they don’t.
- Dashboard Warning Light: Your Camry’s dashboard might display a “key battery low” warning message.
If you’re experiencing these issues, it’s time to replace your key fob battery. Let’s get started!
First, locate the small mechanical key housed within your smart key fob. This key is essential for opening the fob and accessing the battery.
To remove the mechanical key, find the small latch or button on the side of your key fob. Press and hold this latch while gently pulling the mechanical key out of the fob. Set the mechanical key aside for now – we’ll use it to open the fob casing.
Now, look for a narrow slot on the key fob. This slot is usually located perpendicular to where you just removed the mechanical key.
Insert the thinnest end of the mechanical key into this slot. The mechanical key is designed to act as a lever to carefully pry open the two halves of the key fob.
Gently twist the mechanical key within the slot. You should feel a slight give or hear a click as the fob casing begins to separate. Avoid using excessive force, as you only need to pop the case open, not break it.
Once the casing is open, you’ll see the circuit board inside. The battery is located on the underside of this board. It’s held in place within the fob compartment, often secured with a light adhesive or small clips.
Carefully slip the end of the mechanical key underneath the edge of the circuit board. Gently lever the board upwards to lift it out of the compartment. There’s no need to completely remove the board; just lift it enough to access the battery.
You’ll now see the battery, typically held in place by small metal legs or clips. Observe how the battery is positioned so you can correctly insert the new one.
Gently use your fingertip or the tip of the mechanical key to spring open these legs one at a time to release the old battery. Remove the dead battery.
Take note of the battery type. For a 2007 Toyota Camry key fob, you’ll most likely need a CR1632 battery. This is a 3V lithium coin cell battery. You can find these at most drug stores, electronics stores, and online retailers. It’s always a good idea to confirm the battery type before purchasing a replacement.
Insert the new CR1632 battery into the compartment, ensuring the positive (+) side is facing the correct direction (usually upwards). Snap the battery into place, making sure it’s securely held by the retaining legs.
Carefully place the circuit board back into its compartment within the key fob. Align it correctly and gently press it down until it sits flush.
Finally, snap the two halves of the key fob casing back together. You might need to apply a bit of pressure to ensure they are completely closed and secure. You should hear a click as the case snaps shut.
That’s it! You’ve successfully replaced the battery in your 2007 Toyota Camry key fob. Test the buttons to ensure they are working correctly. Your key fob should now be functioning like new.
To maximize the lifespan of your Toyota Camry key fob battery, consider these tips:
- Keep your key fob away from electronic devices: Proximity to devices like cell phones, laptops, and TVs can cause your key fob to constantly “wake up” and drain the battery faster. Store your key fob at least 40 inches away from such electronics when possible.
- Store your spare key fob separately: If you have a spare key fob, store it away from your primary key fob and electronic devices to prevent unnecessary battery drain.
In an emergency situation where your key fob battery is completely dead and your car won’t start, Toyota has included a backup starting method. If your Camry doesn’t recognize your key fob, you can start the engine by holding the back of the key fob (the side with the Toyota logo) directly against the “Start” button on your dashboard. This utilizes a passive RFID chip in the key fob that doesn’t require battery power to communicate with the car in close proximity.
Replacing your 2007 Toyota Camry key fob battery is a straightforward DIY task that can save you money and keep your car running smoothly. By following these simple steps, you can ensure your key fob is always ready to unlock your Camry and get you on your way.
