Is your Toyota key fob not working as reliably as it used to? It might be time for a battery change. Like any battery, the one in your Toyota key fob will eventually need replacing. The good news is, changing the battery in your Toyota key fob is a straightforward process you can easily do yourself at home. This guide from the experts at keyfobx.com will walk you through each step, ensuring you get your key fob back in top shape in no time.
Step-by-Step Guide to Changing Your Toyota Key Fob Battery
Before you head to the dealership or call a locksmith, try replacing the battery yourself. It’s a simple fix that can save you time and money. Here’s how to change the battery in your Toyota key fob:
-
Remove the physical key from the key fob. Locate the small release button on your key fob. This button is usually a small metal piece situated near where the key ring attaches. Press and hold this button, and you should be able to slide the physical key blade out of the fob.
-
Carefully open the key fob casing. Once the key is removed, you’ll see a small slot or seam where you can split the fob casing. Use a small flathead screwdriver or a similar thin, flat tool. Gently insert the tool into the slot and twist or pry carefully to separate the two halves of the key fob. Avoid using excessive force to prevent damaging the plastic casing.
-
Access and remove the old battery. After opening the fob, you’ll see the internal components, including the circuit board and the battery. The battery is usually a small, round, silver disc battery. Gently remove the green circuit board if necessary to access the battery compartment. Take note of the battery’s orientation (positive side up or down) before removing it. This will ensure you install the new battery correctly.
-
Install the new battery. Check the old battery for its type. Most Toyota key fobs use a CR2032 3V lithium battery. You can usually find these batteries at most drugstores, electronics stores, and online retailers. Insert the new CR2032 battery, ensuring it’s placed in the correct orientation as you noted earlier.
-
Reassemble the key fob. Carefully align the two halves of the key fob casing and press them back together until they snap securely into place. Ensure there are no gaps and the casing is firmly closed. Finally, slide the physical key back into the key fob until it clicks and locks into position.
By following these simple steps, you should have successfully changed the battery in your Toyota key fob. Test the fob to ensure it’s working correctly, locking and unlocking your car doors and starting your vehicle if it has push-button start.
Choosing the Right Battery for Your Toyota Key Fob
Using the correct battery is crucial for your Toyota key fob to function properly. As mentioned, the CR2032 battery is the most common type for Toyota key fobs. However, it’s always best to double-check. You can find the exact battery type listed in your Toyota owner’s manual. Alternatively, you can look at the old battery itself; the battery type is usually printed directly on it. Using the correct type and voltage ensures optimal performance and longevity for your key fob.
Changing the battery in your Toyota key fob is a simple maintenance task that can save you from inconvenience and potential costs. By following these steps, you can keep your key fob working reliably for years to come.
