Yanhua CK100 and BGA Adapter program Mercedes Benz W204

Yanhua CK100 is able to program Mercedes Benz W204 by working with one additional BGA Adapter, this news was back to the end of 2016 year, it is not new but some users are not noticed and would like to share here.

  1. Firstly please ensure you have Yanhua CK100 in Black with full adapters (shown as below), for the Yanhua tool the tokens are unlimited and can update online.
  1. Get one BGA Adapter.

BGA Adapter should be used with CKM100, it can’t work alone.

With this adapter, you can perform: 

  1. Read EIS data via OBD (for CAN BUS type)
  2. Read BE key code and write BE key data via infrared
  3. Remove NEC-KEY II chip for reading key code
  4. Original NEC key data collection via infrared and calculate key code (including BGA sealed key)
