2. Information Extraction: The professional uses a specific diagnostic tool to check out data from the lorry's Electronic Ignition Switch (EIS/EZS). This module serves as the "gatekeeper" for the car.
3. Key Calculation: For FBS3 systems, the professional should "calculate" the password of the EIS. This includes taking the encrypted data from the car and utilizing high-powered software application to find the digital key required to configure a brand-new chip.
4. Writing the Key: Once the password is discovered, the service technician "writes" this information onto a blank Mercedes-compatible SmartKey utilizing an infrared key developer.
5. Synchronization: The new key is inserted into the ignition. The automobile acknowledges the brand-new code, and the key "marries" to that specific slot in the automobile's memory.

• Key De-synchronization: In unusual cases, a drop or direct exposure to water can trigger the key's internal memory to corrupt, needing it to be wiped and reprogrammed.
