[MacElliana]

Ford Focus car key battery replacement steps are as follows: 1. Turn the car remote key to the back, and you will see the back cover divided into two parts, with the battery located under the back cover. 2. Look for the gap on the key, usually near the key ring or on the side of the key, but the back cover cannot be removed by hand. 3. Use a flathead screwdriver to insert into the gap, apply slight upward force to lift a part of the back cover, as force is applied at one point, the entire back cover cannot be removed at once. 4. Move the screwdriver along the gap to both sides to gradually widen the gap. The entire back cover can then be lifted. 6. Use your hand to pull the back cover towards the closed end to remove it, revealing the battery inside. 7. On one side of the battery, you will see a protruding clip. Press the clip to remove the battery. 8. Insert the new battery into the car remote key in the opposite direction of removal. Pay attention to the positive and negative poles, and do not install the battery backwards.
