I used Advanced Lock & Security recently for a second time. In both cases, the service was really good! They were changing and re-keying locks in our home for us because we had lost the key to the original locks, which they had also put in for us. These were professional-grade locks, so it was more than your average job. Their professionalism was great! One thing I would note is that there was one item that the guy had said he would follow up on, but I have yet to hear from him. Other than that, from the onset the service was excellent, and the timeliness was great. I was very happy, and I would definitely recommend them to anyone, and I don't say that a lot!
