How to install the indoor door lock

The installation of door locks is often seen in the decoration of new houses, especially the installation of indoor door locks is especially common. In order to let everyone better understand the installation method of indoor door locks, the following Signstek blog will introduce the installation methods of the indoor door locks in detail.

Determine the direction of opening the door

Before installing the door lock, we cannot ignore the direction of opening the door. The direction of opening the door determines which side we will install the lock on when we install the door lock.
So how do you determine the direction to open the door? It's very simple. Open the door and see where the hinge is. Generally, the side where the hinge is on is the direction of the door.
Therefore, installing a door lock on the side of the door where the hinge is not installed can ensure that the direction of the door lock is correct.
Simply put, it means that the locked side is indoors, and the side where the key is inserted is outdoors. If you get it in the wrong direction, it will not be able to protect it.

After confirming the correct direction of the door, you can install the door lock. Don't underestimate the installation of door locks, this is also a very important part of indoor installation.
