Best Way to Secure a Door From the Inside

Ensuring the safety and security of our homes is paramount, and one of the primary areas that require attention is securing our doors from the inside. Whether you want to reinforce your door against potential break-ins or provide additional privacy, implementing effective measures is crucial.

In this comprehensive guide, we will explore the best ways to secure a door from the inside, covering important strategies and techniques that will give you peace of mind.

Best Way to Secure a Door From the Inside

Reinforce the Door Frame

Install a door frame reinforcement plate: Strengthen the door frame by installing a reinforcement plate that adds an extra layer of protection against forced entry. These plates are typically made of metal and are installed around the strike plate area.

Upgrade the Door Lock

  • Install a deadbolt lock: Deadbolt locks are essential for securing doors. Opt for a Grade 1 or Grade 2 deadbolt lock, as they offer higher levels of security compared to Grade 3. Ensure the deadbolt has at least a one-inch throw, and use long screws that penetrate into the door frame for added strength.
  • Consider a smart lock: Smart locks provide convenience and advanced security features. They can be controlled remotely, offer keyless entry options, and often have additional security features like activity monitoring and tamper alerts.

Reinforce Hinges

  • Use hinge pins or security studs: Replace standard hinge pins with security studs or pins that cannot be easily removed when the door is closed. These prevent intruders from removing the hinge and gaining entry.
  • Install hinge-side security pins: These pins add an extra barrier against door removal by preventing the door from being lifted off its hinges.

Install Door Chains or Latches

  • Install a door chain lock: A door chain lock allows you to open the door partially while keeping it secure. This provides an extra layer of protection and allows for controlled interaction with visitors.
  • Use a door viewer (peephole): Install a door viewer at eye level to identify visitors before opening the door. Choose a wide-angle viewer for better visibility.

Reinforce Door Panels

  • Use security film: Apply security film to glass door panels to reinforce them and prevent them from shattering easily. Security film makes it more difficult for intruders to break through the glass.
  • Add a security screen: Install a security screen door or grille to provide an extra physical barrier and prevent unauthorized access.

Implement Additional Security Measures

  • Install a door alarm system: Door alarms emit a loud sound when the door is opened, alerting you and deterring potential intruders.
  • Use door jammers: Door jammers, also known as door security bars, are adjustable bars placed at the base of the door to prevent forced entry. They provide an extra layer of physical resistance.
  • ┬áConsider a door barricade device: Door barricade devices are portable systems that reinforce the door and prevent it from being forced open. They can be easily installed and removed as needed.


Securing your door from the inside requires a multi-faceted approach to ensure optimal protection and peace of mind. By reinforcing the door frame, upgrading the lock, reinforcing hinges, installing door chains or latches, reinforcing door panels, and implementing additional security measures, you can significantly enhance your home’s security.

Remember to choose high-quality products, follow installation instructions carefully, and regularly assess and maintain the security measures you have implemented. With these strategies in place, you can safeguard your home and loved ones against potential intruders and enjoy a greater sense of security within your living space.
