Special door lock
Posted on 2016-10-30
I need a door lock for front door, entrance in house, which can be locked/unlocked with keys from both sides, but from inside to have a special feature. I would need to be in such way that the key could never be forgotten inside or if it is forgotten, then to still be able to unlock it from outside.
It is a metal door at my parents’ house and I would like to prevent an unpleasant situation that happened when the key was forgotten inside, the door locked, the doorbell was ringing, but could not be heard or did not work properly...
