    Default Renew Chinese Mercedes Smart Keys Help...

    Hi Guys,

    I would like to know how to renew incorrectly programmed chinese Mercedes Smart keys, they have a NEC F9234 IC inside. I don't want to have to throw them away and when I ordered them I 'assumed' that by having a NEC IC I would be able to renew them, how wrong was I?

    If I have to replace the IC inside the key, what IC do I use as there appear to be many different F9234 IC's. Any help would be appreciated!

    Thanks!

    Benz chinese key had fault NEC chip. It can programme ONE time and i rmember need write by IR. You need buy new IC and remplace the old and programme.

    Chinese Benz key with F9234 program by IR not on adaptor.

    Calculate key with SKC, convert file with utility and write direct via IR.

    with this cheapest programmer can be BE keys programmed only once... there is not any renew function
    with VVDI MB BGA tool can be through IR programmed....renewed how many times you want...
    by the keys, where was described "programmed only ONCE" too can be renewed how many times you want...
    i self buy this BE keys( programmed only ONCE) before more then Year and no any problem with repeated renewing....
    many thanks to friend kevfield
