Many modern-day German marques utilize 128-bit or 256-bit AES encryption, making it virtually impossible to bypass without the initial maker's software application hooks.

2. The Immobilizer System (ECU/CAS/EIS)

In high-end cars, the key must be "presented" to multiple control modules. For example, in a Mercedes-Benz, the Electronic Ignition Switch (EIS) must recognize the key before it permits the Electronic Steering Lock (ESL) to disengage and the Engine Control Unit (ECU) to fire the injectors.

2. Security Data Extraction: The expert need to "check out" the security information from the car's computer system. In some luxury lorries, this requires getting rid of the module (like the BMW FEM or Mercedes EIS) and reading the data directly from the EEPROM or MCU chip.
3. Key Preparation: A "blank" key that matches the frequency and FCC ID of the car is prepared. For some brands, the key must be pre-coded with the VIN.
4. Synchronization: The new key is introduced to the car's immobilizer system. This includes composing the new key's unique ID into the car's "enabled" list and synchronized the rolling code series.
5. Practical Testing: The service technician evaluates all functions, including remote locking, distance Keyless Entry Programming, push-to-start, and emergency mechanical blade performance.
