Mercedes Benz AK500+ Key Programmer Tech Support
The main difference between AK500+ with SKC calculator and old AK500 pro(sk86):
1) AK500+ with SKC (SK110) has no 8PIN EEPROM adapter holder, because AK500+ with SKC only needs to read out EIS data and send the data to SKC calculator to calculate, then complete key matching;
The old version AK500 has 8PIN EEPROM adapter holder to help read and write ESM data, because AK500+ needs to de-solder EIS, ESM and ESL ECU when it makes Mercedes Benz key.
2) AK500+ with SKC (SK110) support more car models than old version AK500.
3) AK500+ pro can't make key if without SKC calculator; while old version AK500 pro can make key.
4) AK500+ pro with SKC calculator doesn't contain external EEPROM (M95xxx), so it does not need to deal with M95xxx, because AK500+ pro contains SKC calculator, after ak500+ read out EIS data and send it to SKC calculator to calculate, the key data is acquired; The old version AK500 key Pro contains 95XXX, AK500 need to remove chip 95XXX and weld it on the 95XXX adapter.
