Privacy locks are most frequently produced for interior implementation to be used in bathrooms and the like. They are composed of a central button on the interior-facing side that can be used to lock the door, as well as a small slot, or opening, on the opposite side that can be used to unlock the door in emergency situations. The advantage of utilizing privacy locks is that their installation is extremely simple, their capacity to restrict entry in privacy-related situations, and their cost-efficiency. However, given that they are designed for interior applications, they can be picked or opened with force. For this reason, privacy locks should not be installed on exterior property such as the door between the garage and the house, as doing so can abate the safety of your home.
