How to use the Benz IR NEC Key Programmer
Exampel for W210 /W202 /W208/W220
All type under year 2000 need only to modify (EIS and ESL for 210) and(EIS and ESM for W220)
First we have to read 2 mcu from EIS / ESL or ESM and save both as BIN file
choose EIS type
1- load EIS mcu1 load ESL ESL1 or ESM chip93c56
SSID and Pass appear
choose key to generate we choose as example key 5/6/7/8
Files Have Been Save message appear to inform that Mcu1 and ESL1 had modify and save in same folder and key 5/6/7/8 had generate and save in same folder
2- load EIS mcu2 and ESL2 choose key 5/6/7/8 thin press Process
Files Have Been Save message appear to inform that Mcu2 and ESL2 had modify and save in same folder
Write all modify dumps to chip and mcu Now we have end from modify dumps and generate keys .
How to program MCU with NEC Programmer
NEC_Prog dialoge appear select COM port as USB convert statu
Message ( Hardware OK ) must appear . if no’t check USB cable or you have select error port .
Press (load,BIN ) then load BIN key file from folder .
After we insert MCU in ZIF socket press programming
