How to replace the battery of a Toyota 4Runner key?

Model: Toyota 4runner N280 - Years 2010-2024
Part: Key

To replace the battery of a Toyota 4Runner key, start by separating the two halves of the key using a small screwdriver or a coin to pry open the slot. Once the key is open, you will find the battery inside. Take note of the type of battery (usually a CR2032) and carefully remove it. Insert the new battery into the same slot, making sure the polarity is correct, with the positive side facing up. After replacing the battery, close the key by aligning the two halves. Verify the correct functioning of the key by testing it on the vehicle.
