Lost your keys? Not as bad as you think!
Daughter, son, neighbour, cleaning lady - with every person who has a key to your apartment, the risk of loss increases. What do you do if you are not sure whether a key has actually been lost, or if you have lost track of who actually still has a key. Do you really want to replace the whole lock straight away? DOM has a significantly more convenient solution in the program: the 2 in 1 system.
