If you have Mercedes w169 to add new key with VVDI MB BGA tool, I am sure following questions and answers will help you much.
Question:
I have w169 and I need add one more key. so i need read acquisition data from key and calculate password. But what about working key after read password he stops working?
Reply from senior locksmith:
So if I want add key no need read password from working key? Can you explain i new with this tool.
Thanks, if I good understand i need chose read by IR not OBD. I will try.
Question:
For W169 you have the following options:
– calculate the pass with a TOKEN
– get pass from working key if it is v51/v57
– get pass by EEPROM method from EIS
You CANNOT get pass by IR on that car. IR method works only on old(before year 2004) K-line cars and not on all of them.
Question:
Yes I am understand, but question after calculation password from working key token method, original key works or i need renew and program one more time?
because car is far away so i want to be sure.
