How to program Mercedes ML350 05 remote key

Here is the instruction on Mercedes Benz ML350 2005 year remote Key Programmer. Though the car is old, still some asked how to program the remote.

29-1

Old Mercedes ML350 immobilizer system= Key +AAM/EAM+ DEM

Procedure:

29-2

Dissemble AAM computer which located under the left side of the dashboard. The ML350 AAM contains two computer board, one bigger size and another small size. Each board contains MC68HC705X32 Motorola ECU with 0G47V.
29-3

    Read CPU data

We only need to read the 0G47V data on the small AAM CPU board. Do not need to read data from bigger AAM board. This is very important.

29-4

Which ECU Programmer is better to read MC68HC705X32(0G47V)chip data. We recommend Digimaster III(D3) or Xprog M, it is up to you, but it must be stable. For example, if you use Digimaster 3, solder the cpu to D3 adapter.

29-5

    Read and write key

You can use Tango, TM100, VVDI MB BGA Tool to write key, i.e in TM100,we select Generate Key->Mercedes Benz->ML->AAM(7935)
29-6

Update load data just read by Digimaster 3. Select proper key position and insert brand new 7935 chip into TM100 key programmer’s adapter. Follow system prompts to generate ignition key, do not need to re-write key data to 0G47V.  It is difficult to add remote key for old Mercedes. You can buy folding flip Remote Key Shell Case for Benz like picture below.

29-7
Insert the adapter to one end of the original ML350 AAM computer and plug the another end  into the key shell case adapter. The two folding remote key can be used to replace original remote control function.

Then we insert the 7935 chip generated above to folding remote key, a new remote key has been generated.

How to use Tango Key Programmer to make a new key

First, start up the Tango transponder key programmer, connect it to your computer and find “read information” in the “Info” window. Watch memory chip showed in the Data location field. Find out the chip inside of the immobilizer and read it. Save the read data (dump).

Click the “Open Immobilizer File” button and upload the dump.

Tango system will analyze the dump automatically.

If the dump you saved is correct, the “WRITE” button will be actived and the “Keys” window will display the range of key numbers that can be created.

Check the allowed transponder field, and make sure you use a right transponder.

Put the transponder into the coil (the square hole on the tool).

Choose the key bites you want create in the “Keys” window.

Click the “WRITE” button.

The Obd2 Key Programmer transponder will then be written automatically, with data stored.

Save a new immobilizer dump after a new transponder is made.

Save the file after a standard File Save dialog pops up.
