    Default BMW F Series key programming CAS4 ? FEM ?

    Hi all,
    I have a request for a spare key to a BMW 420d, i have experience on doing eeprom work on all BMW's not had an F series yet though, am i right in thinking that there is a Cas4 unit and a FEM unit? Which one should i use to do the eeprom? What are the benefits of either?

    i have Zed Full but have not yet purchased the FEM kit for it and also have VVDI Prog.

    Thanks

    Its FEM. Not cas4. All other info is in Google.

    Ok thanks, its just that on my Zed full eeprom list under cas 4 it lists F series BMW's, on Advanced Keys IQ vehicle database it lists it as a cas4 as well and also on VVDI Prog there is a cas 4 listed for eeprom but it does not give any vehicle details, why would this be?

    FEM based cars, you can do only with a couple of tools...
    like vvdi2, cgdi bmw, explorer, etc.
    need obd connection and eeprom reading/writing...
    just use google...
