MB Smart key RF: is it coded in EZS?

[kanzus]

I just programmed EZS and keys on QFP 80 9S12 MCU: part number 209 545 09 08, Start engine OK, but open OK only with infrared, RF (Radio Frequency) does not work.
I tryed with onother EZS ank Key, it opens both IF and RF.
Car is european, keys also : w203.607 coup? C220 CDI engine 611.962.

I know the European and US radio frequency key are different 315 MHz and 400 MHz.

Do you think that RF radio Frequency is coded in the EZS file ?? So if I use US EZS file into European EZS, i should use US keys ??

Please help !

do you have something to actually read the frequency???if its infrared more likely its the wrong remote..use frequency tester is the best...if not use..mb keyexpert...

frequence difference . but you change a Xtal 13.560 (now mabey 9.860 inside)and move two capacital the frequence is 434.2
