The method for replacing the key battery of a Bestune B70 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 use a flat-head screwdriver with the other hand. Locate the gap in the middle of the top of the key, insert the flat-head screwdriver, and gently pry the key up and down until a gap is created. 3. Remove the key circuit board, gently push one side of the battery 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. Reassemble the key cover in reverse order.
