New Mercedes-Benz E200-CDI key battery replacement steps are as follows: 1. Remove the mechanical key and locate the open indicator at the bottom of the key. 2. Use a screwdriver to rotate the key housing 90 degrees at the bottom position. 3. Once the old battery inside the key is visible, remove it. 4. After inserting the new battery, first insert the top of the housing and then press firmly on the other end. 5. Finally, reattach the mechanical key to complete the process. Here are some behaviors that can easily damage the car key: (1) Dropping from a height, as the internal circuitry of the key has relatively weak impact resistance and can be easily damaged by severe collisions. (2) Water exposure, if water seeps inside and damages the circuitry, it can also cause the remote control to malfunction.
