Is your Toyota Camry key fob not working as reliably as it used to? You might be facing a common issue: a dead or dying key fob battery. Fortunately, replacing the battery in your Toyota Camry key fob is a straightforward task you can easily do yourself, saving you time and money compared to dealership service. This guide will walk you through each step to replace your Toyota Camry Key Fob Battery, ensuring you’re back on the road with a functional smart key in no time.
Before we dive into the steps, it’s worth noting that low key fob battery life is a frequent occurrence, especially in modern smart keys. Proximity to electronic devices can sometimes drain the battery faster than expected. Toyota even issued a service bulletin highlighting this, suggesting keeping smart keys away from items like cell phones and computers to maximize battery life. While completely isolating your key fob might be impractical, understanding this potential drain can be helpful.
This guide is primarily for the 2007-2011 Toyota Camry models, but the process is generally similar for other Camry years and various Toyota models. However, key fob designs and battery types can differ, so always double-check your owner’s manual if you’re unsure. Typically, your Camry’s dashboard display will warn you with a “low key battery” message when it’s time for a replacement, giving you a heads-up before the battery completely dies.
Let’s get started with the battery replacement process. The only tool you’ll need is the mechanical key conveniently stored within your smart key fob itself.
First, locate the release latch on the side of your key fob. Press and hold this latch while gently pulling out the mechanical key. This key is designed to not only manually unlock your car door but also to help open the key fob casing.
With the mechanical key removed, you’ll notice a narrow slot at the end of the key fob, perpendicular to where you just removed the key. This is the prying slot we’ll use to open the casing.
Insert the tip of the mechanical key into this slot. Gently twist the key. You don’t need excessive force; a slight twisting motion should be enough to start separating the two halves of the key fob. You might hear a click as the casing begins to open.
Once the fob is open, you’ll see the circuit board. The battery is located on the underside of this board. The circuit board is usually held in place by a light adhesive or small clips. Carefully slide the end of the mechanical key under the edge of the circuit board and gently lever it upwards to detach it from the casing.
Now you can see the battery. It’s typically held in place by small metal legs or clips. Carefully use your fingertip or the mechanical key to gently spring these legs open one at a time, freeing the old battery. Remove the depleted battery.
Take note of the battery type. Toyota Camry key fobs often use a CR1632 battery. While not as common as AA or AAA batteries, CR1632 batteries are readily available. You can find them at most drugstores, electronics stores like Radio Shack or Batteries Plus, and online retailers. Ensure you purchase a fresh CR1632 battery for optimal performance.
Install the new CR1632 battery, making sure the polarity is correct (usually the positive side facing up). Secure it in place by gently pressing the retaining legs back into their original position. Place the circuit board back into its compartment, ensuring 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 securely closed.
Once reassembled, test your key fob. Try locking and unlocking your car remotely and starting the engine. If everything works as expected, you’ve successfully replaced your Toyota Camry key fob battery!
Battery Type and Where to Buy
As mentioned, the Toyota Camry key fob commonly uses a CR1632 battery. It’s always best to double-check your owner’s manual or the markings on your old battery to confirm the exact type. You can purchase CR1632 batteries at:
- Drugstores (CVS, Walgreens, etc.)
- Electronics stores (Best Buy, Radio Shack, Batteries Plus, etc.)
- Online retailers (Amazon, eBay, etc.)
- Some auto parts stores
Tips for Battery Longevity
To extend the life of your Toyota Camry key fob battery:
- Keep your key fob away from electronic devices when possible, especially overnight.
- Avoid storing your key fob in extreme temperatures.
- Consider replacing the battery every 2-3 years as preventative maintenance.
What if Your Car Doesn’t Start Immediately?
In rare cases, even with a new battery, your car might not immediately recognize the key fob. If this happens, Toyota has a backup starting method. Hold the back of your key fob (the side with the Toyota logo) directly against the “Start” button on your dashboard. This usually allows the car to detect the key fob passively and start the engine. Refer to your owner’s manual for detailed instructions on this emergency starting procedure.
Replacing your Toyota Camry key fob battery is a simple and cost-effective DIY task. By following these steps, you can ensure your smart key remains functional and reliable, providing you with seamless access and operation of your vehicle.
