VVDI MB Tool support read key password online,and each time cost 1 token,if all key lost will cost 2 tokens.
And we received feedback from customer that when read key pass,it got the error
And the Cars doesnt start anymore
No key working anymore and elv is loked
Suggestion from engineer:
remove the EIS read the eeprom by soldering with VVDI PROG, prepare key file by eeprom and make new keys
