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. Fortunately, replacing the battery in your 2009 Toyota Camry key fob is a straightforward process you can easily do yourself, saving time and money compared to dealership service. This guide will walk you through identifying the correct battery type and provide step-by-step instructions for a smooth replacement.
Identifying the Correct Battery Type for Your 2009 Toyota Camry Key Fob
The battery type you’ll need for your 2009 Toyota Camry key fob is a CR1632 battery. This is a 3V lithium coin cell battery that is commonly used in small electronic devices, including car key fobs. You can find CR1632 batteries at most drug stores, electronics stores, retailers like Walmart or Target, and online marketplaces like Amazon. Keeping the correct battery type in mind is the first step to a successful replacement.
Step-by-Step Guide to Replacing Your 2009 Toyota Camry Key Fob Battery
Replacing the battery in your 2009 Toyota Camry key fob is a simple DIY task that requires no special tools beyond the mechanical key already in your possession. Follow these steps to get your key fob working like new again:
Step 1: Remove the Mechanical Key
Locate the small latch on the side of your 2009 Toyota Camry key fob. Press and hold this latch while gently pulling out the mechanical key. This key is designed to be used as a tool for opening the fob casing, as well as an emergency backup to unlock your car door manually.
Step 2: Locate the Notch and Insert the Mechanical Key
Examine the key fob to find a narrow slot located perpendicular to where you just removed the mechanical key. This slot is designed to allow you to pry open the fob casing. Insert the end of the mechanical key into this slot.
Step 3: Twist to Open the Key Fob Casing
Once the mechanical key is inserted into the slot, gently twist the key. This twisting motion will apply leverage and pop open the two halves of the key fob casing. You may hear a click as the casing separates.
Step 4: Access the Circuit Board and Battery
With the key fob casing open, you will see a circuit board inside. The battery is located on the underside of this circuit board. The circuit board might be lightly adhered to the casing with double-sided tape.
Step 5: Remove the Old CR1632 Battery
Carefully slide the end of the mechanical key underneath the circuit board and gently lift to lever it out of the compartment. Once the circuit board is flipped over, you will see the CR1632 battery held in place by small metal clips or legs. Use your fingertip or the mechanical key to gently spring open these clips one at a time to release the old battery.
Step 6: Install the New CR1632 Battery
Take your new CR1632 battery and insert it into the battery compartment, ensuring the positive (+) side of the battery is facing upwards (usually indicated with a “+” symbol on the battery and/or the compartment). Press the battery down until it is securely held in place by the clips.
Step 7: Reassemble the Key Fob
Place the circuit board back into its compartment within the key fob casing. Snap the two halves of the key fob casing back together. You may need to apply a bit of pressure to ensure they are fully closed and securely fastened.
Step 8: Test Your Key Fob
Once reassembled, test your 2009 Toyota Camry key fob to ensure it is working correctly. Try locking and unlocking your car remotely and starting your vehicle using the smart key system.
Why Did My 2009 Toyota Camry Key Fob Battery Die So Quickly?
You might be wondering why your key fob battery needed replacing. Toyota service bulletins have noted that “Smart Keys” can be activated by electronic “pings” from nearby devices. Storing your key fob close to electronic devices can lead to premature battery drain. Common culprits include:
- Cell phones and smartphones
- Laptop computers and tablets
- TVs and computer monitors
- Cordless phones
- DVD and VCR units
To maximize the battery life of your 2009 Toyota Camry key fob, try to store it at least 40 inches (1 meter) away from these types of electronic devices when not in use.
Low Battery Warning in Your 2009 Toyota Camry
Many 2009 Toyota Camry models are equipped with a low key fob battery warning system. If you see a warning message on your dashboard display indicating a low key battery, it’s a good indicator that your battery is nearing the end of its life and should be replaced soon to avoid unexpected key fob failure.
Emergency Start with a Dead Key Fob Battery
Even if your 2009 Toyota Camry key fob battery is completely dead, you can still start your car in an emergency. Place the back side 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 fob passively and start the engine. Remember to replace the battery as soon as possible after using this emergency starting method.
Save Money with DIY Key Fob Battery Replacement
Dealerships often charge significant labor fees for simple services like key fob battery replacement. By following these easy steps and replacing the CR1632 battery yourself, you can save a considerable amount of money and keep your 2009 Toyota Camry key fob working perfectly. You can purchase a CR1632 battery for a few dollars at many local stores or online, making this a very cost-effective DIY repair.
