We had a laugh when he flipped it over and it worked. He could have screwed me over for $200 and I wouldn't have known the difference. Instead he sent me on my way at a cost of $0 and a laugh. I wouldn't hesitate to use him in the future. Thank you Lu!

He quickly diagnosed the problem, called his supplier for the part and said he could be back to the next day to do the install. He said he would call with an ETA, which he did (it's amazing how often contractors SAY they will do something and don't), arrived right on time and quickly made the fix, with a really nice attention to detail to make sure everything was perfect. I really appreciate Mike's professionalism and attention to detail - makes me wish I had more problem locks!

Finally it was time to do something. I was sitting at a car dealership waiting for my car to be serviced and I had Yelp find me a locksmith. Within a just a few minutes I had responses from two locksmiths. Star Locksmiths, Bulent, was reasonably priced and at my home the next morning. The install was quick and he rekeyed the lock to match our existing keys. He even adjusted the handle for the regular lock (below) so the cold air wouldn't come through between the door and the door frame. We were really pleased and will use Star Locksmiths again.
