Attempting to break a door knob without proper technique can lead to injury or further damage to the door.

What You Need

Required Tools To Break A Door Knob With A Hammer

Breaking a door knob with a hammer is not as complicated as it sounds. You don’t need highly specialized tools. All you need are basic tools that most people have in their homes. The required tools are:

  • A hammer: You can use any hammer type, but the most common and suitable one is the claw hammer. Make sure you select the right weight of hammer that you can handle easily.
  • Pliers: You will use them to remove the remaining pieces of the broken knob.
  • Screwdrivers: These are necessary if you need to remove any parts of the door or knob before breaking it with the hammer.
  • Safety glasses: You will need to protect your eyes from debris flying off the knob when you hit it with the hammer.

Tips For Choosing The Right Hammer

Selecting the right type of hammer for the job is crucial. Here are some tips to keep in mind when choosing a hammer for breaking a door knob:

  • Weight: The weight of the hammer that you choose should be something that you feel comfortable with. If it’s too heavy, it will be challenging to control, causing more damage than required, and if the hammer is too light, it may not generate the required force to break the knob.
  • Material: The hammer material determines its durability and weight. A high-quality steel or titanium hammer is better than other alloys since it can withstand repetitive impacts and is less likely to break or warp over time.
  • Claw: A hammer with a claw allows you to use it as a lever to remove the broken pieces of the knob. It would help if you looked for a hammer with a claw as it makes the job much more comfortable.

Safety Precautions

Breaking a door knob with a hammer may sound adventurous, but it comes with inherent risks. Here are some safety measures to consider before starting the process:

  • Wear safety glasses: Wearing protective goggles is essential to protect your eyes from flying debris, dust or debris that may come during the process
  • Ensure your surroundings are safe: Ensure that the area around the door is clear of debris, and there is nothing that could trip you up or cause an accident.
  • Check for electricity wires and natural gas pipes: If you have a suspicion that the door is close to any of these, do not proceed with the method. Instead, seek professional assistance.
  • Be prepared for loud noises: Breaking a door knob with a hammer will create some loud noises. Ensure that you use earplugs to prevent any hearing damage.

Alternative Methods

Other Methods To Break A Door Knob

Although using a hammer is the most common method for breaking a door knob, there are other methods that you can use if you don’t have a hammer or other breaking tools. Here are some of the alternative methods that may work for you:

  • Using a screwdriver: You can use a screwdriver to force the locking mechanism inside the knob. Insert the screwdriver into the keyhole, and then turn it in the same direction as the key would turn. With enough force, the locking mechanism should break, and you can open the door.
  • Using a wrench: If you have a wrench with you, you can use it to twist the knob until it breaks. Insert the wrench into the knob, and then turn it until you hear a snap. With the right amount of force, the knob should break, allowing you to open the door.
