[VanBrody]

The method to replace the battery in an old Toyota car key is as follows: 1. There is a round button on the side of the car key. Press this button with one hand while pulling out the mechanical key with the other hand; 2. Hold the key with one hand and a flat-head screwdriver with the other. Locate the gap in the middle of the top of the key, insert the screwdriver, and gently pry the key open until a gap appears; 3. Remove the key circuit board, gently push the battery out from one side with your finger, and take out the old battery. Place the new battery with the positive side facing up into the battery slot, and gently push it until it is fully secured; 4. Cover the key circuit board back onto the key, align the two separated halves of the key, and press both sides of the key with your hands until the upper and lower parts are completely joined. Then, insert the mechanical key back into the key gap, and the battery replacement is complete.
