It’s a Mercedes Benz W220 older model with K-line. All keys have lost. w220 (k) kline you cannot read it by IR or by OBD unless you have a working key.
Some of them are different and you can make key only by removing MCU. It has a 2 big square processor chips.
The older w220’s are one of the hardest EIS’s to program a key too. Most tools will not read the info to calculate the password and will require the removal of the EIS and the removal of the MCU to be able to get the info needed to calculate the password.
For this old of EIS you have to take out EIS and desolder the MCU and read dump directly to get password. This is the only good way to do it.
Autel IM508/IM608 with XP400 Pro can also do this.
Remove the EIS, remove the MCU on the EIS, solder the MCU chip to the Autel’s APB128 adapter. Read MCU info to calculate the password and program key.
