How do you secure a French door when open? French doors add an elegant touch to your home, allowing natural light to flood in while providing a seamless connection between indoor and outdoor spaces. 

However, their aesthetic appeal should not overshadow the importance of security. Keeping your French doors secure when open is crucial to prevent unauthorized access and maintain the safety of your home. 

In this article, we’ll explore effective ways to enhance the security of your French doors while they’re open.

How Do You Secure a French Door When Open?

Securing a French door when open requires a combination of smart strategies and modern security solutions. 

By implementing these measures, you can enjoy the fresh air and the beauty of your surroundings without compromising your home’s safety.

1. Choose Reinforced Hardware

When your French doors are open, they become potential entry points for intruders. Reinforce your doors with heavy-duty locks, hinges, and handles that are designed to withstand tampering. 

Opt for multipoint locking systems that secure the door at multiple points, making it much harder for anyone to force it open.

2. Install Security Screens

Security screens act as a protective barrier against insects, debris, and unauthorized access. 

These screens are designed to be robust and difficult to breach, providing an additional layer of security when your French doors are open.

3. Utilize Door Sensors

Modern home security systems offer door sensors that trigger an alert whenever the door is opened. 

Connect these sensors to your home security system to receive real-time notifications on your phone or other devices, helping you stay vigilant even when you’re not at home.

4. Add Window Film

Consider applying shatter-resistant window film to the glass panels of your French doors. This film holds the glass together even if it’s shattered, making it much more difficult for intruders to gain access.

5. Use Security Bars or Grilles

Security bars or grilles provide an effective physical barrier against forced entry. They can be easily installed and act as a strong deterrent, discouraging potential intruders from targeting your home.

6. Place Security Cameras Strategically

Strategically place security cameras around your French doors to monitor any suspicious activity. Visible cameras can discourage wrongdoers, while hidden cameras can capture valuable evidence if needed.

7. Trim Landscaping Near the Doors

Overgrown bushes and trees near your French doors can provide cover for intruders. Regularly trim your landscaping to eliminate potential hiding spots and ensure a clear line of sight.

8. Use Timers for Indoor Lights

When your French doors are open in the evening, it’s important to maintain a well-lit indoor space. Use timers to automatically turn on lights, creating the illusion that someone is at home even when you’re enjoying the outdoors.

9. Secure Valuables Out of Sight

If your French doors are open, make sure valuable items are not easily visible from the outside. This prevents temptation for potential thieves who might be scouting for easy targets.

10. Keep Valuables Away from the Doors

Avoid placing valuable items close to the French doors, even when they’re closed. This prevents someone from breaking the glass and quickly grabbing items within arm’s reach.

11. Implement Smart Locks

Smart locks allow you to remotely control and monitor your French doors. You can lock or unlock them using your smartphone, receive activity alerts, and even grant temporary access to guests.

12. Create a Secure Perimeter

Consider installing motion-sensor lights around the perimeter of your home. These lights will illuminate whenever someone approaches, deterring potential intruders from getting too close.

13. Educate Household Members

Ensure that everyone in your household is aware of the importance of security. Teach them to lock doors and windows when they’re open, even if they’re only stepping away momentarily.

14. Lock the Non-Active Door

If your French doors have one active and one inactive panel, always keep the inactive panel locked. This reduces the number of entry points and makes it more challenging for intruders.

15. Use a Security Bar or Dowel

Placing a security bar or dowel in the track of the sliding French door prevents it from being opened from the outside, adding an extra layer of security.

16. Invest in a Monitored Security System

Consider investing in a professionally monitored security system. These systems provide round-the-clock monitoring and can dispatch authorities in case of an emergency.

17. Opt for Impact-Resistant Glass

If you’re installing new French doors, consider using impact-resistant glass. This type of glass is designed to withstand strong impacts, making it much harder for intruders to break.

18. Secure Patio Furniture

Keep patio furniture and other objects away from the French doors. These items could be used by intruders to gain access to your home.

19. Regular Maintenance

Regularly inspect and maintain your French doors’ hardware, locks, and security features. Address any issues promptly to ensure they remain effective.

20. Neighborhood Watch

Participate in or establish a neighborhood watch program. Community vigilance can deter criminals and create a safer environment for everyone.


How do you secure a French door when open? Securing your French doors when open is essential for maintaining a safe and secure home environment. 

By implementing a combination of modern security solutions, smart practices, and awareness, you can enjoy the beauty of your surroundings without compromising your peace of mind.
