CGDI MB Unlock Mercedes EIS Key Position
This Mercedes EIS has 4 positions already in used, but we only have one car key in hand now.
So I will delete the other three key positions by CGDI MB Benz Key Programmer.
Step-by-step to unlock EIS key position:
Step 1: Get the erase password
We have calculated the EIS password, next step is to get the erase password now.
Save EIS data with password
After saving the file successfully, go to get the erase password.
Connect CGDI Prog MB to internet
Erase password calculated successfully
Use the simulation key when we erase the EIS.
I have connected analog key (simulation key)
Step 2: Wipe the EIS
Follow the prompt to insert the simulation key into EIS
Done, and it shows erase succeed, click OK
Then read the EIS data again
It’s empty EIS now. The personalized and activated options are not marked now.
Then load the EIS file which has password info inside.
Step 3: Write VIN &EIS data
Write the VIN first, then write the EIS data
Parts of the EIS only allows write VIN once, go to continue
Write the VIN successfully, and go to write the EIS file
Insert the simulation key into the EIS in 30 seconds
Write the EIS successfully
Step 4: Activate the original key
Remove the simulator key and insert the original key into the EIS to start the car
Restart again, it works fine!
Also test the remote
The remote is good too.
Finally, read the EIS data again
Now there’s only one key position left, the other key positions have been cleared.
