The new Mercedes device is working with smart key (old and new) used since 1997 up to 2005 (without
 Key Less Go system). You can program new key (ore used one) in car and program own key if it can not work more. You read and program eeprom of CPU from Steering blocking module via diagnostic connector (38 pins). Desolder and read in programming tool two CPU from Electronic Ignition Control Module. Load these eeproms to program. Desolder NEC CPU from the key. Solder it on the device , select the No of key and program it. Solder all CPUs on their places and start the car.
You can program new keys without the car - only with EIS and steering blocking modules. You can read these CPUs with help programming tool (for ex. ETL) for Motorolla CPU 68HC705X16(32).

Current features:
Easy and convenient generator of microprocessor software dumps
Support of keys based on the NEC controller. Such as 0x28, 0x35, 0x40, 0x51, 0x57, 0x61, 0x71, 0x81, 0x229.
Ability to check status and proper operation of Electronic Steering Lock (ESL)
Ability to program ESL right on a car (No need to replace it)
