Is your Toyota Camry key fob starting to act up? Perhaps you’ve noticed the range decreasing, or it’s becoming less responsive. One of the most common culprits is a low battery. Fortunately, replacing the battery in your Toyota Camry key fob is a straightforward process that you can easily do yourself. This guide will walk you through each step to get your key fob working like new again, saving you time and potentially a trip to the dealership.
Replacing your Toyota Camry key fob battery is simpler than you might think. With a few readily available tools and a few minutes of your time, you can restore your key fob’s functionality. Let’s get started.
Step-by-Step Guide to Toyota Camry Key Fob Battery Replacement
Follow these simple steps to replace the battery in your Toyota Camry key fob:
Step 1: Remove the Mechanical Key
Begin by locating the small metal button on your Toyota Camry key fob. This button is usually situated near the key ring loop or above the mechanical key portion of the fob. Press and hold this button. While pressing the button, gently pull out the mechanical key from the key fob. Set the mechanical key aside in a safe place. This key is a backup and can be used to manually unlock your car door if needed.
Step 2: Open the Key Fob Casing
With the mechanical key removed, you’ll notice a small slot or indentation where the key was housed. This slot is designed to allow you to carefully open the key fob casing. Take a small flathead screwdriver or a similar thin, flat object. Gently insert the tip of the screwdriver into the slot. Apply a slight twisting motion to carefully pry open the two halves of the key fob casing. Be gentle to avoid damaging the plastic casing. The fob should pop open relatively easily.
Step 3: Access and Remove the Old Battery
Once the key fob is open, you will see the internal components, including a green circuit board. Carefully lift and remove the green circuit board from the casing. It should lift out easily, but handle it with care to avoid damaging any of the small electronic components. Beneath the circuit board, you will find the battery. Take note of the type of battery currently in place. Most Toyota Camry key fobs use a CR2032 3V battery. You can confirm the exact battery type by checking the label on the old battery or consulting your Toyota Camry owner’s manual.
Step 4: Install the New Battery
With the old battery removed, take your new CR2032 3V battery. Ensure that you are inserting the new battery with the correct polarity. Usually, the positive (+) side of the battery should be facing upwards, but double-check the markings in the battery compartment to be certain. Press the new battery firmly into place.
Step 5: Reassemble the Key Fob
Carefully place the green circuit board back into its position within the key fob casing. Make sure it sits correctly and is aligned with the casing. Now, align the two halves of the key fob casing and gently press them together until they snap securely back into place. You should hear a click indicating that the casing is properly closed. Finally, slide the mechanical key back into the key fob until it clicks into its locked position.
