4. Key Programming: This password is programmed onto a new, unassigned Mercedes-Benz compatible chip key.
5. Emergency Situation Blade Cutting: The specialist utilizes a CNC laser-cutting maker to cut the small mechanical blade hidden inside the fob, ensuring the driver can still get in the vehicle if the battery dies.
