Is your Toyota key fob failing to unlock your doors reliably, or perhaps the range has diminished significantly? The most likely culprit is a dying battery. Fortunately, replacing the battery in your Toyota key fob is a straightforward process you can easily handle yourself, saving you time and a trip to the dealership for a minor issue. This guide will walk you through each step of Toyota key fob battery replacement, ensuring you get your key fob working like new again.
Step-by-Step Toyota Key Fob Battery Replacement
Changing the battery in your Toyota key fob is a simple DIY task. Follow these easy steps to restore your key fob’s functionality:
-
Remove the Mechanical Key: Locate the small button on your key fob, typically a metal or plastic release catch situated near the key ring. Press and hold this button while gently pulling out the physical key blade from the fob. This key is a backup to manually unlock your car door and needs to be removed to access the key fob casing.
-
Open the Key Fob Casing: After removing the key, you’ll find a small slot or seam where the key blade was housed. This is where you’ll open the key fob. Insert a small flathead screwdriver or a thin, sturdy object like a credit card or plastic pry tool into this slot. Carefully twist or gently pry to split the key fob casing open. Avoid using excessive force to prevent damage to the plastic.
-
Access and Remove the Circuit Board: Once the casing is open, you will see the internal components, including a green circuit board. Gently lift or maneuver the circuit board to access the battery compartment underneath. Be careful when handling the circuit board to avoid touching or damaging any sensitive electronic components.
-
Identify and Replace the Old Battery: The battery is usually a small, round, silver disc battery. Take note of the battery type printed on it. Most Toyota key fobs use a CR2032 3V lithium battery. You can find replacement CR2032 batteries at most drugstores, supermarkets, electronics stores, and online retailers. Carefully remove the old battery and insert the new CR2032 battery, ensuring the positive (+) side is facing upwards, as indicated by markings in the battery compartment.
-
Reassemble Your Key Fob: With the new battery in place, carefully put the circuit board back into its position within the key fob casing. Align the two halves of the key 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 and locks into position.
When You Might Need a Full Toyota Key Fob Replacement
While battery replacement solves most key fob issues, sometimes a full Toyota key fob replacement is necessary. This might be the case if your key fob is lost, severely damaged, or malfunctioning even after a battery change.
If you require a complete Toyota key fob replacement, contacting your local Toyota dealership’s parts department is the best course of action. They can provide you with a genuine Toyota key fob programmed specifically for your vehicle. Remember to inquire about any parts specials that might be available to save on your replacement. Furthermore, if you only need a replacement physical key blade without the fob, the dealership can also assist with cutting a new key for you.
