In some extreme "all keys lost" circumstances for brand names like Audi or Mercedes, the professional might require to remove the security module (EEPROM) and read the information directly from the chip.
Phase 3: Clearing Old Data
If a key has actually been lost or stolen, it is vital to "de-program" the old key. The service technician accesses the lorry's immobilizer memory and erases the lost key's digital footprint, ensuring it can no longer be used to begin or go into the car.
Stage 4: Programming the New Transponder
The new key is placed in a special programming slot or held near the induction coil. The software then uploads the distinct encrypted ID to the car's ECU (Engine Control Unit). This procedure might take anywhere from 15 minutes to over an hour, depending upon the intricacy of the car's firewall program.
Stage 5: Functional Testing
A detailed test is carried out. This includes:
