The advent of door lock has greatly enhanced our home security. It helps us turn away intruders and also lets people into our room.

How Do We Lock Door From Inside？

Most door locks work with a bolt: when you want to lock the door, slide the bolt from the door into the doorframe; to unlock the door, remove the bolt from the doorframe.

You just have to learn how to slide and remove the bolt.

For most mechanical locks, there is a push-lock or twist-lock button on the inner doorknob.

Push-lock button

You can find a small, cylindrical button protruding from the center of the knob. When your door is closed, you can push the button to lock the door.
Now, people can’t open the door without the key.
If you want to unlock the door, just simply turn the knob from the inside.

Twist-lock button

There should be a circular button with a ridge down the center.
To lock the door from the inside, you can pinch the ridge and twist the button clockwise as far as it will go (likely a 90-degree quarter-turn) with the door closed.
Simply twist the button counter-clockwise to the place where it was before locking it from the inside.

With the rise of high technology, our life is becoming more and more convenient than ever before.

In the domain of home security, various products have been made to translate our lives into better ones. The keyless door lock is one of the most remarkable inventions.

The traditional door lock is replaced with the keyless door lock, such as electronic keypad door lock, fingerprint lock, and smart door lock with Wi-fi or Bluetooth.

You no longer have to keep a set of keys in your carry-on bag or your pocket and worry about your keys being stolen one day.

Keypad door locks are designed to be opened with codes.

By default, only by entering the right codes can you open the door, and knowing the codes means that you already get the permission of the host.

So, most keypad door locks have no lock from inside function.

However, double insurance can strengthen your security.
