I went to Advanced Lock & Security recently to have a lock and keypad installed at my building, and was quite happy with how the work had gone. The people that came out were very thorough in explaining exactly how the equipment functions, and very competent while installing the lock and keypad. Overall I thought the work was done very well, and the keypad and lock have been working without any issues. I would definitely use them again if needed, and I highly recommend their services.
