Replaced my FOB key. I had a keyless entry FOB key and lost the whole set of keys. I was mostly concerned about the FOB because all the other keys were pretty easy to replace. He was able to do it from his van. It didn’t take too long, but it was a bit pricey, though for a Benz, I expected it to be a lot more actually. Give him max rating for speed and service. Great locksmith.
