Q: I own Mercedes-Benz VVDI MB BGA Tool key programmer.
I bought EIS W221 lock with a key from the lock from one machine.
I have read the PSW. I will make a complete loss of W221 key in the future?
A:You have used/2nd-hand EIS with working key, you can do like this for W221 all key lost
Read all key lost EIS data-> save EIS data
read used EIS data enter password, get erase password->renew used EIS.
Load step1 EIS data to renewed EIS with password->write EIS data
Load EIS data (with key password)->prepare key file
Input new key to device IR reader->load key file->write
Insert new key to EIS->EIS will learn the new key->key learn success
By the way, if your all key lost W221 is Motorola EIS, not need to change EIS, remove eis get eeprom by programmer (VVDI PROG)
Then load eeprom to VVDI MB TOOL prepare key file.
