Does AK500PRO Support Mercedes Benz W204 After 2008?
Answer: so far AK500PRO doesn't support NEC eeprom key programming, but support AK500pro NEC eeprom key calculation.
W204 is with NEC eeprom, therefore AK500pro neither supports W204 nor supports the following Mercedes Benz models: w204/w207/w221/w218 and W164 after 2008 year which EIS model CPU is NEC.

Important Notice on KEYLESS GO Function

If you want to use KEYLESS GO function: the key used to make key must be new and blank key, it can't be used key. New key must be as the same type and frequency as the original keyless go key. Otherwise it will cannot support keyless go function.
AK500 do ESL: read out original ESL data, generate new key data, write new data .binw back to ESL( now must use that 32GB hard disk database then can renew ESL)
When you deal W203 ECU, if your ECU is simens, it do not have eeprom. Resolution: Read flash of ecu, then make renew. Then use MB STAR to do doing.
AK500PRO can write keyless go key. But you must wirte via IR( Your keyless go key must be completely new or blank. If your key is old, it can read out date, then it can not be write again, you must renew it then can write).
