How to Use Interior Door Locks

Interior door locks are simple locks that are not meant to be used for home security, but rather to keep out unwelcome guests from a bedroom or bathroom while you are using it. These locks are not meant to withstand a lot of pressure, and will break if pushed on hard enough. You should only use this type of lock on the interior of your home where privacy is needed.




  1. Purchase the type of interior door lock that you wish to use in your home. There are different types to choose from such as locks that open with a key, small twist locks that are located in the center of the door knob, or interior locks that have a small button that needs to be depressed in order to lock the door. Choose the style that suites your needs and preferences.

  2. Install this interior lock onto the doors in your home where you want privacy such as a bedroom, bathroom or office. You will simply need to remove the old door handle using a standard screwdriver, and then follow the manufacturer’s directions for installing the new interior door locks that you have purchased.

  3. Be aware that some styles of locks do not have a way to get into them once you have closed the door and it is locked on the other side. If this is a concern for you, you should choose a key lock, or the style that has a small hole on the middle of the door handle on the outside of the door. You can insert a thin metal object into this hole to disengage the locking mechanism.

  4. Keep a spare key handy if you have interior doors that require a key to enter. You never know when you may become locked out of a room, and need the key to enter. It is best to keep an extra key in the house just in case.
