Is your Toyota key fob acting up? Maybe you have to press the buttons multiple times, or perhaps it’s stopped working altogether. Before you assume the worst, the most common culprit is often a simple fix: a dead battery. Replacing the battery in your Toyota key fob is a straightforward process you can easily do at home, saving you time and money. This guide from the experts at Keyfobx.com will walk you through each step of a Toyota Key Fob Battery replacement, and also cover what to do if you need a complete Toyota key fob replacement.
Step-by-Step Toyota Key Fob Battery Replacement
Changing your Toyota key fob battery is easier than you might think. You won’t need any special tools, and the whole process should only take a few minutes. Here’s how to do it:
-
Remove the Mechanical Key: Locate the small release button on your key fob. This button is usually a small metal or plastic catch situated near the key ring loop or above the physical key itself. Press and hold this button while gently pulling the mechanical key out of the fob. This key is a backup to manually unlock your car door.
-
Open the Key Fob Casing: Once the key is removed, you’ll see a small slot or seam where the key was inserted. This is where you’ll carefully split open the fob. Use a small flathead screwdriver or a similar thin, flat object (like a guitar pick or even a butter knife) to gently pry open the fob. Insert the flat tool into the slot and twist gently. The fob casing is usually made of two pieces that snap together, so you should feel it begin to separate. Be careful not to apply excessive force to avoid damaging the plastic casing.
-
Access the Circuit Board and Battery: With the fob open, you’ll see the internal components, including a green circuit board. Carefully lift or remove the circuit board to access the battery underneath. Sometimes the battery is directly visible once the fob is open, depending on the model. Handle the circuit board with care to avoid damaging any small components.
-
Identify and Replace the Battery: Take a look at the battery currently in place. You’ll likely see a small code printed on it, indicating the battery type. The most common Toyota key fob battery is a CR2032 3V lithium battery. You can confirm the correct battery type in your Toyota owner’s manual if needed. You can purchase a replacement CR2032 battery at most drugstores, supermarkets, electronics stores, and online retailers. Remove the old battery and insert the new one, making sure the positive (+) side is facing the correct direction (usually upwards).
-
Reassemble the Key Fob: Carefully place the circuit board back into its position within the fob casing. Align the two halves of the fob casing and press them firmly together until they snap securely back into place. Ensure there are no gaps and the casing is fully closed. Finally, slide the mechanical key back into the key fob until it clicks into its locked position.
When Do You Need a Complete Toyota Key Fob Replacement?
While a dead battery is the most frequent issue, sometimes a Toyota key fob replacement is necessary. Here are a few scenarios where you might need to replace the entire fob:
- Lost Key Fob: If you’ve lost your key fob, replacement is essential to maintain your vehicle’s security.
- Damaged Key Fob: If your key fob has been severely damaged – for example, dropped in water, crushed, or physically broken – it might not be repairable, even with a new battery.
- Malfunctioning Fob (Beyond Battery): In rare cases, the key fob itself may malfunction due to internal electronic issues unrelated to the battery. If a new battery doesn’t solve the problem, the fob itself might be faulty.
