your region determine the frequency- if you in europe- will be 433mhz, if you in usa will be 315mhz.

look at the dashboard if in MILES it means 315 if its in KM its 433 EASY


in benz u can program any keys on the car if its 315 or 433 and it will run the car , and its easy to change frequency of keys from 315 to 433 and vise versa
