It happens to every Toyota owner eventually – you press the button on your key fob, and nothing happens. Your trusty key fob, the gateway to your vehicle’s convenience features, has a dead battery. Don’t worry, you don’t need to rush to the dealership immediately. Replacing the battery in your Toyota key fob is a straightforward process you can easily do yourself. This guide will walk you through each step of how to remove the battery from your Toyota key fob and get you back on the road quickly.
Step-by-Step Guide to Toyota Key Fob Battery Removal
Changing your Toyota key fob battery is a simple task that requires minimal tools and time. Follow these easy steps to get your key fob working again:
-
Locate and Remove the Mechanical Key: Almost all Toyota key fobs contain a physical key for manual entry. Look for a small button or release latch on your key fob. This is usually a metallic button situated near the key ring loop or along the side of the fob. Press and hold this button while gently pulling out the mechanical key. Set the key aside in a safe place.
-
Prepare to Open the Key Fob Casing: With the mechanical key removed, you’ll notice a small slot or notch where the key was just positioned. This slot is designed to help you open the key fob casing.
-
Carefully Open the Fob Casing: Insert a small flathead screwdriver or a thin, sturdy object (like the edge of a credit card or a plastic trim removal tool) into the slot you located in the previous step. Gently twist or pry to separate the two halves of the key fob. Avoid using excessive force to prevent damage to the plastic casing. Work your way around the seam if needed until the fob pops open.
-
Access the Battery Compartment: Once the key fob is open, you will see the internal components, including a small circuit board and the battery. The battery is usually a small, round, silver disc battery and is typically held in place by small clips or within a battery holder.
-
Remove the Old Battery: Carefully note the orientation of the battery (positive side up or down) before removing it. This will ensure you install the new battery correctly. You can use your fingertip or the tip of a small screwdriver to gently pry the old battery out of its compartment.
-
Identify the Correct Replacement Battery: Before heading to the store, take a look at the old battery. The battery type is usually printed directly on it. Most Toyota key fobs use a CR2032 3V lithium battery. However, it’s always best to double-check the markings on your old battery or consult your Toyota owner’s manual to confirm the exact battery type required for your specific key fob model.
-
Install the New Battery: Take your new battery (CR2032 or the type specified for your fob). Install the new battery into the compartment, ensuring the polarity is correct (match the orientation you noted when removing the old battery). The positive (+) side of the battery typically faces upwards, but refer to the markings in the battery compartment if unsure. Press down gently until the battery is securely in place.
-
Reassemble the Key Fob: Carefully align the two halves of the key fob casing and press them firmly back together until they snap closed. Ensure there are no gaps and the casing is securely sealed.
-
Reinsert the Mechanical Key: Slide the mechanical key back into its slot until it clicks into place.
-
Test Your Key Fob: Press the buttons on your key fob to test if it’s working correctly. You should now be able to lock and unlock your doors, and use other key fob functions as usual.
What Battery Does My Toyota Key Fob Need?
As mentioned, the most common battery type for Toyota key fobs is the CR2032 3V lithium battery. This is a widely available and inexpensive battery that you can purchase at most drug stores, supermarkets, electronics stores, and online retailers. However, some Toyota models or older key fobs might use different battery types, such as CR2025 or CR1632. Always verify the correct battery type by checking your old battery or your Toyota owner’s manual. Your owner’s manual is a valuable resource for information specific to your Toyota model, including key fob battery replacement.
