We had to rekey all the office doors after a security breach, so we called Minneapolis Door & Lock, full disclosure: We have been working with them for over two years and their team came over quickly to help us out. These guys are very professional and efficient, got everything done quickly including cutting 2 keys for each door, 2 new grand master keys and 6 sub master keys. As always they are very easy to deal with and great pleasure to work with and we recommend them to every business, big or small.
