car diagnostic tool

Today i wanna share how to use the xhorse vvdi mb bag tool, i take these problems as an example: 

steps on W221 W204 all key lost, change W204 ESL and get a new ESL for W204

If W221 all key lost

You have used/second handed EIS with working key, you can do like this for W221 all key lost

  1. Read all key lost EIS data-> save EIS data
  2. read used EIS data enter password, get erase password->renew used EIS.
  3. Load step1 EIS data to renewed EIS with password->write EIS data
  4. Load EIS data (with key password)->prepare key file
  5. Input new key to device IR reader->load key file->write
  6. Insert new key to EIS->EIS will learn the new key->key learn success

By the way, if your all key lost W221 is Motorola EIS, not need to change EIS, remove eis get eeprom by programmer (VVDI PROG).

Then load eeprom to VVDI MB TOOL prepare key file.
