As for Mercedes-Benz key programming, which one should you take? Ak500 key programmer or Ak500 pro key machine?
| Products | AK500+ key programmer | AK500 Pro key programmer |
| Figure |
|
|
| Read & write EIS | Yes, no issues on HC705/HC908/HC912/9S12 | Yes, no issues on HC705/HC908/HC912/9S12 |
| MB original factory key calculator | No | Yes |
| Remove ESL/ESM/ECU | Yes, it needs to remove ESL/ESM/ECU to synchronize data | No need to remove ESL/ESM/ECU
Support calculating key only need EIS data |
| Write old model big keys | No, it doesn’t support infrared write old model big key (Motorola CPU) |
Yes, it supports infrared write old model big key (Motorola CPU) |
| Program infrared keys | Yes, it program infrared keys for Mercedes Benz from1998 to 2005 | Yes, it program infrared keys for all Mercedes from 1998 to 2011 |
| Program W203 W211 keys | No | Yes, it supports MB W203/W211 key programming with ECU flash 29F400 and 29F800 |
| Read & write “Key-less go” Key | No | Yes, it supports reading and writing “Key-less go” key |
| Reset SBC computer | Yes, but not via OBD to read and write SBC EEPROM | Yes, it can read and write SBC EEPROM via OBD. |
| Support EGS | No, it doesn’t support EGS which is 722.9 type of gearbox computer |
Yes, it supports EGS which is 722.9 type of gearbox computer |
| Need database | Yes, it needs 320G database to support ESL fast unlocks | No need database and supports ESL fast unlocks |
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.
