The single button ones exist, I bought one just dig around a bit. A complete unit from MB is ~ $ 150 ( can't get the housing ) you will need to provide title / owners card and your picture ID. Some MB dealers need to see the car also through I don't think this is MB policy.

I try to buy non China but they seem to be the only ones willing to put an effort forth to make key programmers , key housings and the like. I won't buy china bearings or something I can get in the US.

My parts counter manager who I deal with (wholesale account) tells me as of the past couple of months this has become MB policy. Some dealers asked for it before, but now MB wants the dealers to program the new key. Eliminate any lost keys off of the cars key program, and send back a form to Mercedes showing they deactivated any lost keys and show what keys remain active. That's only for the key in like my E55 and my CDI. Obviously the W124 keys he still just hands me over the counter.

Could be apocryphal. But that is what he told me.

There's lots of confusion regarding MB replacement key policy. Yes, ownership must be proved, ID verified, and the key pre-paid by the OWNER of the vehicle. The only surrogates allowed are indie service providers. In any case, an authorized dealership employee MUST verify that the key works. My dealership has authorized the parts dept. delivery drivers to make things simple. De-programming lost/stolen keys is NOT required by MB but the client can choose to do this at their expense. Hope this clears things up.......
