So having only had 1 key since Feb and the previous owner not replying decided to bite bullet and contact a dealer - 1st try MB dealer no joy tried Chrysler dealer locally again no joy, then rang dealer that said he could supply 6 months ago - he is also definite that cannot get me a key! when is a Chrysler dealer not a Chrysler dealer. That's the bad news but there maybe a solution (sell car did I hear) I spoke to an auto locksmith who says he can supply me a non remote transponder key to open door & start car - waiting on quote will keep you all updated
