Are your keys still hanging unprotected on a board on the wall? Anyone can steal or take them? We strongly advise against this and recommend that you purchase a key cassette. A key cassette is made of robust steel. They are locked using a cylinder key lock.
The key cassettes can be easily mounted on the wall with 2 screws, so no witchcraft and yet your keys are now safely stored.
Of course, Rottner Security offers key cassettes in different sizes and helps you with the selection. Just contact us!
