Just like any battery-operated device, your Toyota Tacoma key fob relies on a small battery to function. Knowing the correct Toyota Tacoma Key Fob Battery Size is crucial for a smooth replacement and ensuring you’re never caught off guard. This guide will walk you through everything you need to know about your Tacoma key fob battery, from identifying the size to replacing it yourself.
Identifying the Correct Battery Size for Your Toyota Tacoma Key Fob
The most common battery size for Toyota Tacoma key fobs, across various model years, is the CR2032 battery. This is a 3V lithium coin cell battery that provides long-lasting power in a compact size, perfectly suited for the small form factor of your key fob.
While the CR2032 is the standard for most Tacoma key fobs, it’s always best practice to double-check. Here’s how you can confirm the exact battery size for your specific Tacoma key fob:
- Check your Owner’s Manual: Your Toyota Tacoma owner’s manual is your best resource. Look for the section on “Key Fob Battery Replacement” or “Remote Control” – it should specify the exact battery type required for your vehicle’s key fob.
- Examine the Old Battery: Once you open your key fob (as detailed in the next section), you can directly look at the old battery. The battery size (likely CR2032) is usually printed clearly on the battery itself.
Step-by-Step Guide to Toyota Tacoma Key Fob Battery Replacement
Replacing your Toyota Tacoma key fob battery is a straightforward process you can easily do at home. Here’s a step-by-step guide:
-
Remove the Mechanical Key: Locate the small button, usually metallic, on your key fob. Press and hold this button to release the mechanical key blade from the fob. Slide the key out and set it aside. This key can be used to manually unlock your car door if needed.
-
Open the Key Fob Casing: After removing the key, you’ll see a small slot or notch where the key was housed. Insert a small flathead screwdriver or a thin pry tool into this slot. Gently twist or pry to separate the two halves of the key fob casing. Take your time and avoid using excessive force to prevent damage to the plastic.
-
Access and Remove the Old Battery: Carefully open the fob. You may see a green circuit board. Gently lift or maneuver the circuit board to access the battery compartment underneath. Note the orientation of the old battery (positive side up or down) before removing it. You can typically pry the old battery out using your fingertip or the edge of a small tool.
-
Install the New CR2032 Battery: Take your new CR2032 battery and install it in the battery compartment, ensuring the correct orientation (match the positive and negative sides as the old battery was placed). Push the battery firmly into place until it’s securely seated.
-
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 blade back into its slot in the key fob until it clicks into place.
