I've called 5 locksmiths to duplicate a transponder key for my Mercedes Benz they declined.
I received a call from Heritage locksmith and they came out within a few hours and did the job within an hour and a half. He told me at first it'll be done within half an hour but I kind of figured it would be longer than that.
I was not upset. it was kind of pricey but glad they were able to do it
