Step-by-Step Guide to Replacing Your Toyota Key Fob Battery
Replacing the battery in your Toyota key fob is a simple task that usually takes just a few minutes. Follow these steps to get your key fob working like new again:
-
Locate and Remove the Mechanical Key: Most Toyota key fobs come with a physical key hidden inside. Look for a small release button, usually a metallic or black button located on the fob. Press and hold this button while simultaneously pulling out the mechanical key. Set the key aside in a safe place.
-
Open the Key Fob Casing: Once the mechanical key is removed, you’ll see a small slot or notch where the key was located. This is where you’ll need to gently pry open the key fob. Use a small flathead screwdriver or a thin plastic prying tool. Insert the tool into the slot and carefully twist or gently pry to separate the two halves of the key fob casing. Be patient and avoid using excessive force to prevent damage to the plastic.
-
Access the 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, coin-shaped battery. In many Toyota key fobs, the circuit board might be held in place by small plastic clips. Gently lift the circuit board to access the battery underneath. Handle the circuit board with care to avoid damaging any of the electronic components.
-
Identify the Old Battery Type: Before removing the old battery, take note of the battery type and orientation. Most Toyota key fobs use a CR2032 3V lithium battery. The battery type is usually printed directly on the battery itself. Make sure to note which side is facing up (+) and which is facing down (-). This is crucial for installing the new battery correctly.
-
Remove the Old Battery and Install the New One: Carefully remove the old battery. You might be able to pry it out with your fingertip or the small screwdriver. Once the old battery is out, take your new replacement battery for toyota key fob (CR2032 or the type specified for your model) and install it in the same orientation as the old one. Ensure the positive (+) side is facing the correct direction as you noted earlier. The battery should snap or fit snugly into place.
-
Reassemble the Key Fob: Carefully place the circuit board back into its position, ensuring it’s properly aligned. Then, align the two halves of the key fob casing and press them firmly together until they snap back into place. Make sure the casing is completely closed with no gaps.
-
Test Your Key Fob: Insert the mechanical key back into the fob until it clicks into place. Now, test your Toyota key fob by trying to lock and unlock your car remotely. If it works, congratulations! You’ve successfully completed your Toyota key fob battery replacement. If it doesn’t work, double-check that you installed the battery correctly and that the battery type is correct.
When You Might Need a Full Toyota Key Fob Replacement
While a battery replacement solves most key fob issues, there are times when you might need a complete Toyota key fob replacement. This includes situations such as:
- Lost or Stolen Key Fob: If you’ve lost your key fob or it has been stolen, a replacement is necessary for security reasons.
- Damaged Key Fob: If your key fob is physically damaged, cracked, or water-damaged to the point where it’s no longer functional, replacement is often the best option.
- Malfunctioning Key Fob (Beyond Battery): In some cases, the key fob itself may malfunction due to internal electronic issues that are not related to the battery. If a new battery doesn’t solve the problem, a replacement fob might be needed.
If you find yourself needing a full Toyota key fob replacement, it’s best to contact your local Toyota dealership’s parts department.
