If the codes match, the guiding lock is released, and the car can start.

4. Key Programming: This password is set onto a new, unassigned Mercedes-Benz compatible chip key.
5. Emergency Situation Blade Cutting: The expert uses a CNC laser-cutting device to cut the little mechanical blade concealed inside the fob, making sure the chauffeur can still go into the vehicle if the battery dies.
6. Testing: The new key is checked for ignition, remote entry, and Keyless-Go performance.
