Xhorse VVDI PROG + MB BGA Tool Program Benz W209 EIS AKL

Today we've got a Mercedes Benz W209 ignition switch with all keys lost. When I open it up, it's written W211, ST12 on the board. So next I'm gonna use Xhorse VVDI PROG + VVDI MB BGA Tool to program a key for the Mercedes.

It may save time if I had the solder-free Xhorse EZS Adapters, only to insert ST12 adapter into the board. Unfortunately, I don't have one. I should hook them up with the wires soldered.

Step 1. Read & Save EEPROM

Now we're ready to get the eeprom info with VVDI PROG.

Select:

Type: 4-IMMOBILIZER, Brand: BENZ, Chip: EIZ-W211(ST12)

Click "Read", then save the file.

Step 2. Save EIS File

Take all wires off the board, then connect to MB BGA Tool.

After loading EIS data/ Motorola EEPROM dump from step1, it gives me all the key password and FBS data.

Save EIS data >> press OK to save HC05 format file

Step 3. Prepare Key File

Prepare key file >> Load EIS file >> Select key position: Key3 >> Prepare key file

Wait for a few seconds, finished.

Step 4. Program Key

Let's put together the key to program it. Plug the key into MB Tool slot.

Read write key >> Identification key.

It comes up as a BE Key.

Load key file in step3>> Write.

Okay, it's written and completed.

Take out the key for a test, remember to put a battery inside.

It does turn on.

That's all done!
