In sum,

 

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.
