David was very knowledgeable and informative, he and was in an out within ab hour, he rekeyed 5 doors at our office and charged us the same price as their job estimate they’ve sent us, he also offered to repair our back door doorknob and installed a metal reinforcement plate on the door which was a big help as well. David was very kind and it was  a pleasure working with him, we would absolutely continue working with these guys.
