i got my chrome key online....before MBUSA put the stop to online Smartkey ordering.
they also updated their Theft Relevant policy and made it clear to dealers that they cannot
do this anymore, and asked owners to bring their car to the dealer with proof of ownership.
they made one exception which was that if the car could not be driven or towed in, that
the dealer could send out an MB qualified locksmith to the location.
