We needed to rekey all doors at our office after a minor security breach, and also needed a master key that unlock them all, Adam was the our technician and he absolutely amazing, super responsive and easy to talk to, he quoted a very affordable price upfront, was very punctual and worked promptly to finish the job as quickly as possible, he did a fantastic job, made sure everything was done to our fully satisfaction, and was absolutely fun to work with, highly recommend Adam and Baltimore Door & Lock!
