Just like any battery-operated device, your Toyota key fob relies on a battery to function. Knowing the correct Toyota Key Fob Battery Type is crucial for ensuring your remote continues to lock, unlock, and start your vehicle without a hitch. This guide will walk you through identifying the right battery for your Toyota key fob and provide a simple step-by-step process for replacing it yourself.
Replacing your Toyota key fob battery is a straightforward task that can save you time and money compared to visiting a dealership for a minor issue. The most common Toyota key fob battery type is the CR2032 3V lithium coin battery. However, it’s always best to double-check to be absolutely certain.
To determine the exact Toyota key fob battery type for your specific model, there are a couple of easy methods:
- Check the Old Battery: Once you open your key fob (as detailed in the steps below), the battery type is usually printed directly on the battery itself. This is the most reliable way to confirm.
- Consult Your Owner’s Manual: Your Toyota owner’s manual is a wealth of information and should specify the correct battery type for your key fob within the vehicle information or key section.
While CR2032 batteries are widely used in many Toyota models, variations might exist depending on the year and specific model of your Toyota. Always prioritize verifying the Toyota key fob battery type before purchasing a replacement to avoid compatibility issues.
Once you have the correct replacement battery, follow these simple steps to replace it:
-
Remove the Mechanical Key: Locate the small button on your Toyota key fob, usually a metallic release catch positioned near the key ring. Press and hold this button to release and slide out the mechanical key from the fob.
-
Open the Key Fob Casing: After removing the key, you’ll see a small slot or seam where the key was housed. Insert a small flathead screwdriver or a similar thin, flat object into this slot. Gently twist or pry to separate the two halves of the key fob casing. Take care not to apply excessive force to avoid damaging the plastic.
-
Access and Remove the Circuit Board: Carefully open the fob to expose the internal components. You’ll typically see a green circuit board. Gently lift or maneuver the circuit board out of the casing to access the battery compartment underneath. Be cautious when handling the circuit board to prevent any damage to its delicate electronic components.
-
Replace the Old Battery with the New Battery: With the circuit board removed or flipped over, you’ll now see the battery. Take note of the orientation of the old battery (+ side up or down) before removing it. Gently pry out the old battery. Install the new Toyota key fob battery type, ensuring it’s inserted in the correct orientation. For most Toyota key fobs using CR2032 batteries, the positive (+) side usually faces upwards.
-
Reassemble the Key Fob: Carefully place the circuit board back into its position within the fob casing. Snap the two halves of the key fob casing back together until they are securely closed. Finally, slide the mechanical key back into the key fob until it clicks into place.
