Just like any electronic device, your Toyota key fob relies on a battery to function, sending signals to lock, unlock, and even start your vehicle remotely. Eventually, this battery will need replacing. If you’re a Toyota owner, knowing “What Kind Of Battery Does A Toyota Key Fob Take” is crucial for maintaining your key fob’s functionality and avoiding any unexpected lockouts. This guide from Keyfobx.com, your trusted auto repair resource, will walk you through identifying the correct battery and replacing it with ease.
Identifying the Right Battery for Your Toyota Key Fob
The most common type of battery found in Toyota key fobs is the CR2032 3V lithium coin cell battery. This small, circular battery is widely available and known for its long-lasting power, making it ideal for key fobs. However, while the CR2032 is prevalent, it’s always best to double-check to ensure you’re using the correct battery for your specific Toyota model and key fob type.
How can you confirm the exact battery your Toyota key fob requires? There are a couple of reliable methods:
-
Check the Old Battery: Once you open your key fob (we’ll guide you through that process shortly), carefully remove the existing battery. You’ll find the battery type clearly printed on it. Note down this code – it will likely be CR2032 or a similar variant.
-
Consult Your Toyota Owner’s Manual: Your vehicle’s owner’s manual is a treasure trove of information. Look up the section on key fob battery replacement. It should specify the exact battery type recommended for your Toyota key fob.
While CR2032 batteries are the most frequent, some Toyota models might occasionally use slightly different batteries like CR2025 or CR1632. Always prioritize verifying the specific type to guarantee optimal performance and avoid any damage to your key fob.
Step-by-Step Toyota Key Fob Battery Replacement
Replacing your Toyota key fob battery is a simple process you can accomplish at home in just a few minutes. Here’s a step-by-step guide:
-
Remove the Mechanical Key: Locate the small release button on your key fob, usually a metallic button situated near the key ring attachment. Press and hold this button while gently pulling out the mechanical key from the fob.
-
Open the Key Fob Casing: After removing the key, you’ll notice a small slot or notch where the key was inserted. Use a small flathead screwdriver or a similar thin, flat object. Carefully insert the tool into the slot and gently twist or pry to separate the two halves of the key fob casing. Take your time to avoid damaging the plastic.
-
Access and Remove the Old Battery: Once the fob is open, you’ll see the internal components, including the green circuit board and the battery. In most Toyota key fobs, the battery is easily accessible. Note the orientation of the old battery (positive side up or down) before removing it. You might be able to gently pry it out with your fingertip or the small screwdriver.
-
Insert the New Battery: Take your new CR2032 battery (or the type specified for your fob). Ensure you insert it with the correct polarity, matching the orientation of the old battery you just removed. Usually, the positive (+) side of the battery faces upwards, but double-check the markings inside the battery compartment.
-
Reassemble the Key Fob: Carefully align the two halves of the key fob casing and press them firmly back together until they snap securely into place. Ensure there are no gaps and the casing is properly closed. Finally, slide the mechanical key back into the key fob until it clicks and locks.
After reassembly, test your Toyota key fob to ensure it’s working correctly. If the battery replacement was successful, your key fob should now lock/unlock your doors and start your vehicle (if equipped with remote start) without any issues.
What If You Need a Full Toyota Key Fob Replacement?
While battery replacement is straightforward, there are instances where you might need a complete Toyota key fob replacement. If your key fob is lost, damaged beyond repair, or malfunctioning even after a battery change, a replacement is necessary.
For a full Toyota key fob replacement, it’s recommended to contact your local Toyota dealership or a certified automotive locksmith. They have the expertise and equipment to program a new key fob specifically for your Toyota vehicle. Keep in mind that full key fob replacements usually involve programming costs in addition to the cost of the key fob itself.
