  4. Lost Key replacement

    General E46 Forum
    Hello good people, I lost one key and would like to fix the replacement. Any tips on where to buy OEM one? I saw somebody selling a single used key on ebay - isn't the key "cut" unique? Could one possibly buy a used key and reprogram it? I looked up the part number; 01104444444, it's discontinued.
