Is your 2009 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. Don’t worry, replacing it is a straightforward task you can easily handle yourself, saving you time and money compared to dealership service. This guide will walk you through each step of replacing your 2009 Toyota Camry key fob battery and tell you the exact battery size you need.
Many owners of the 2009 Toyota Camry, and similar models, experience the frustration of a weakening key fob battery. You might notice that you need to be closer to your vehicle for the remote to function, or the “key not detected” warning appearing on your dashboard. These are clear signs that it’s time for a battery change. Before you rush to the dealership, know that this is a simple DIY fix.
The good news is that for your 2009 Toyota Camry key fob, you’ll likely need a CR1632 battery. This is a common button cell battery that’s readily available at most drug stores, electronics stores, and online retailers. While battery life can vary, factors like proximity to electronic devices can impact it. Electronic devices emit signals that can keep your key fob in a “wake-up” state, even when not in use, thus draining the battery faster. Toyota even issued a service bulletin regarding this, advising owners to keep their smart keys at least 40 inches away from devices like cell phones, TVs, and computers to maximize battery life. However, in our modern, tech-filled lives, this can be quite challenging!
Let’s get started with the battery replacement. The only tool you’ll need is the mechanical key that’s hidden inside your smart key fob itself.
First, locate the small latch on the side of your Toyota Camry 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 you open the key fob case.
Now that you have the mechanical key removed, look for a narrow slot on the key fob. This slot is usually perpendicular to where you just removed the mechanical key. Insert the thinner end of the mechanical key into this slot.
With the mechanical key inserted in the slot, gently twist the key. This twisting motion will apply leverage and pop open the two halves of the key fob casing. You might hear a slight click as the case separates.
Once the key fob is open, you’ll see the circuit board. The battery is located on the underside of this board. Carefully slide the end of the mechanical key underneath the circuit board. It’s held in place with a light adhesive, so gently lever the board upwards to detach it from the case.
You now have access to the battery. The 2009 Toyota Camry Key Fob Battery Size is CR1632. It’s held in place by small metal clips or legs. Carefully use your fingertip or the tip of the mechanical key to gently spring these legs open, one at a time, to release the old battery.
Take your new CR1632 battery and install it in the same orientation as the old one (usually positive side up, but check the markings on the battery compartment if unsure). Press it firmly into place until it’s securely held by the metal clips.
With the new battery in place, reassemble the key fob in reverse order. Place the circuit board back into its compartment, ensuring it sits flush. Then, snap the two halves of the key fob casing back together. You might need to apply a bit of pressure until you hear a click, ensuring it’s properly closed.
That’s it! You’ve successfully replaced the battery in your 2009 Toyota Camry key fob. Test the fob to ensure it’s working correctly, locking and unlocking your doors remotely.
Where to Buy CR1632 Batteries
As mentioned, CR1632 batteries are widely available. You can find them at:
- Drug stores (like Walgreens, CVS)
- Electronics stores (like Best Buy, RadioShack – if available, or similar stores)
- Big box retailers (like Walmart, Target)
- Online retailers (like Amazon, eBay)
- Specialty battery stores (like Batteries Plus)
What if Your Car Doesn’t Start After Battery Replacement?
In the rare case that your car doesn’t immediately recognize the key fob after battery replacement, or if your battery was completely dead before replacement, your 2009 Toyota Camry has a backup starting method. Simply place the back of your key fob (the side with the Toyota logo) directly against the “Start” button on your dashboard. This will allow the car to detect the key and start the engine, even with a very low or newly replaced battery.
Replacing your 2009 Toyota Camry key fob battery is a simple and cost-effective way to keep your car running smoothly. By knowing the correct 2009 Toyota Camry key fob battery size (CR1632) and following these easy steps, you can avoid expensive dealership charges and get back on the road with a functional key fob in no time.
