How to Replace the Battery in a Lavida Car Key?

[VanRobert]

The steps to replace the battery in a Lavida car key are: 1. Prepare the necessary tools for battery replacement: a flat-head screwdriver, the car key that needs a new battery, and a new battery; 2. There is a round button on the side of the car key. Press the button with one hand and pull out the mechanical key with the other hand; 3. Hold the key with one hand and the flat-head screwdriver with the other. Locate the gap in the middle of the top of the key, insert the flat-head screwdriver, and gently pry the key open until a gap appears; 4. Take out the key circuit board, push the battery out from one side with your finger, remove the old battery, place the new battery with the positive side facing up into the battery slot, and push the battery until it is fully secured; 5. Cover the key circuit board back onto the key, align the two halves of the key properly, press both sides of the key with your hands until the two halves are completely joined, and then insert the mechanical key back into the key gap.
