Security is the most important parameter for apartment entrance doors. An issue that also affects the mental health of the family. Therefore, the apartment door fittings should automatically lock the door while being beautiful and functional when closing to prevent financial and life damage. A lock that meets the necessary security standards and has passed various performance tests to prevent theft. Cylinders resistant to picking, resistant to drilling and balling, lock tabs resistant to dilema and lock body resistant to acid, are among the security components of Japanese locks with more than 100 years of lock production history. Also, fully closing the door automatically and using a hidden latch that is not visible on the door can help with this issue. The use of new technologies such as automatic seals that prevent energy loss and the entry of dust into the building are also among the other features of entrance doors.
