84 300d sedan: lost key (not orig)

I am a locksmith and this would be no problem for me. I suggest what you say when you call is that you need a key impressioned for your ignition, and another locksmith suggested that it takes the X83 blank.

You are lucky that you have the 300D, if you had the 300SD that uses the sidewinder key and is much more expensive to have a key fit.

thanks for the help!

i just ordered a key from mercedes with my vin #.

it was $16 so i figured why not try it. the last guy didn't know s*it.

thanks for the advice though. i hope i don't have to use it but it's great to know!

In your original post you said

If the original ignition was replaced, the key you get from the dealer is going to work the locks that were not replaced.

When you were driving the car did you have one key or was there a separate key for the ignition?

yeah. they are different.

does that mean this factory key prob won't work?

It will work in the locks that were original but not the replaced locks just like what an earlier post said.

That is correct. The factory only knows what was in the car when it left. But like I suggested before, a reasonably competent locksmith can impression a key to fit the new ignition, so not to worry. Just call around and ask with the information that I gave you the first time.
