Due to the design flaws of a few OEM shells, pressing the button forcefully may cause a short circuit on the circuit board, resulting in  battery leakage.
To avoid this problem, it is recommended to put insulating tape on the area shown in the figure below.

  2. Generate semi-smart key: v51 version is deputy & non-smart key, v41 version is smart key.



  1. Manually modify key frequency(default 315HMz, remove circuit board resistance to be 433HMz;
  2. Infrared switch in VVDI MB Tool;
  3. Supported BGA keys including 212, 221, 204, 216, 207, etc. (Generally 2010+ FBS3 vehicles, not supported FBS4);
  4. Upgrade smart key version with VVDI MB;
  5. Infrared ease key repeatedly.
