now i have a used FEM without key , but its takes 315 mhz , is there anyway i can change the frequency inside FEM from 315mhz to 4343mhz
yes you can change frequency of used fem from cas replacement --.advanced once its unlocked.
Replacing FEM/BDC with used when no communication with original
1.Unlock and reset mileage for used FEM/BDC in Autohex
• if got working key unlock using it
OR
•Use option 3
2.Read ISN from original DME
3.write DME ISN to FEM from ISN manager option 4
4.change VIN for FEM/BDC(Cas replacement-->Advanced)
5.Program key if needed
6.connect FEM/BDC to car
7.Restore FA from FA manager
8.Go out to main menu and come inside coding/programming
9.Program GW and BODY from indiv programming (note it will do only coding because fem already updated)
10.Finish
Did you checked original fem on bench with autohex?
