Is your 2009 Toyota Camry key fob not working as reliably as it used to? Perhaps you’ve noticed you need to be closer to your car for it to unlock, or maybe it’s stopped working altogether. One of the most common culprits is a dead or dying key fob battery. Fortunately, replacing the battery in your 09 Camry key fob is a straightforward process you can easily do yourself in just a few minutes. This guide will walk you through each step, ensuring you get your key fob back in perfect working order without needing to visit a dealership.
The good news is that you don’t need any special tools, and the battery itself is readily available. Let’s get started and show you how to replace your 09 Camry Key Fob Battery quickly and efficiently.
First, you’ll need to locate the small mechanical key housed within your smart key fob. This key is essential for opening the fob and accessing the battery. Look for a small latch or button on the side of your key fob.
Push this latch and gently pull the mechanical key out of the fob. Set the key aside, as you’ll be using it again shortly.
Now, take a closer look at the key fob where you just removed the mechanical key. You’ll notice a narrow slot that runs perpendicular to the opening where the key was housed. This is where we’ll insert the end of the mechanical key to begin opening the fob.
Take the mechanical key and insert the thinner end into this slot. Make sure it’s inserted firmly into the slot.
With the mechanical key inserted into the slot, gently twist the key. This twisting motion will apply pressure to the key fob casing and cause it to pop open. You might hear a slight click as the two halves of the fob begin to separate. Don’t force it; a gentle twist should be enough to start opening the case.
Once the fob is open, you’ll see the internal circuit board. The battery is located on the other side of this board. The circuit board is typically held in place with a light adhesive or clips. To access the battery, you’ll need to carefully remove the circuit board.
Using the end of the mechanical key again, gently slip it under the edge of the circuit board. Carefully lever the board upwards to lift it out of its compartment. Be gentle to avoid damaging the circuit board or any of its components.
With the circuit board removed, you’ll now have access to the battery. The 09 Camry key fob battery is a CR1632 type. It’s a small, circular battery held in place by little metal legs or clips.
Carefully take note of the battery’s orientation – usually, the positive (+) side is facing upwards. Gently pry open the small legs or clips that are holding the battery in place, one at a time, to release the old battery. Remove the dead battery.
Now, take your new CR1632 battery and install it in the key fob, ensuring the positive (+) side is facing the correct direction (usually upwards, matching the orientation of the old battery). Push the battery down until it’s securely held in place by the retaining legs or clips.
Once the new battery is in place, carefully reposition the circuit board back into its compartment. Make sure it sits flush and is properly aligned.
Finally, snap the two halves of the key fob casing back together. You may need to apply a bit of pressure to ensure they close completely and securely. You should hear a click when they are properly rejoined.
That’s it! You’ve successfully replaced the battery in your 09 Camry key fob. Test the key fob to ensure it’s working correctly, locking and unlocking your doors and starting your car. With a fresh battery, your key fob should be working reliably again for years to come. Replacing your 09 Camry key fob battery is a simple and cost-effective way to maintain your vehicle and avoid any inconvenience caused by a dead key fob.
