What Types of Locks Are Best for French Doors?

French doors add elegance and natural light to your home, but security should always be a priority. Let’s delve into the details of the different lock types and explore how you can enhance the security of your French doors.

Types of Locks for French Doors

Here are some types of locks for French doors:

1. Deadbolt Locks

Deadbolt locks are a popular choice for French doors due to their robust security features. They provide a strong bolt that extends into the door frame, making it challenging for intruders to force the door open. 

Opt for a double-cylinder deadbolt that requires a key from both sides for added security. These locks are particularly effective when combined with other security measures.

2. Point Locking Systems

Multi-point locking systems offer enhanced security by locking the door at multiple points along the frame. This mechanism distributes the force applied during a break-in attempt, making it significantly more difficult to pry the door open. 

With the turn of a single key or lever, you engage multiple locking points, ensuring comprehensive protection.

3. Flush Bolts

Flush bolts are often used in pairs on the inactive door of French doors. They are discreetly installed on the top and bottom of the door and slide into corresponding holes in the door frame. 

Flush bolts are easy to operate and provide an additional layer of security, preventing the door from being forced open when not in use.

4. Keyed Locksets

Keyed locksets offer convenience and security. They come with a knob or lever on one side and a key-operated lock on the other. 

Choose a lockset with a hardened steel bolt and a secure strike plate for optimal protection. These locks are suitable for both active and inactive doors.

5. Patio Door Locks

If your French doors lead to a patio or garden, consider installing patio door locks.

These locks are designed specifically for sliding doors and offer secure locking mechanisms to prevent unauthorized access. Choose from various styles, including foot-operated locks and handle locks.

Factors to Consider When Choosing Locks

Selecting the right locks for your French doors requires careful consideration of several factors.

1. Security Level

The primary purpose of locks is to ensure the security of your home. Choose locks that are known for their durability and resistance to tampering. Multi-point locking systems and deadbolts are excellent options for achieving a high level of security.

2. Aesthetics and Design

While security is crucial, you also want locks that complement the design of your French doors. Look for locks that seamlessly integrate with the door’s aesthetics, whether you prefer modern, traditional, or vintage styles.

3. Ease of Use

Locks should be user-friendly for both residents and guests. Opt for locks that are easy to operate, especially in emergency situations. Keyless entry systems and smart locks can provide convenience without compromising security.

4. Durability

French door locks are exposed to the elements, so durability is key. Choose locks made from high-quality materials that can withstand changing weather conditions. Stainless steel and brass locks are known for their longevity.

5. Budget

Locks come in a range of price points. While it’s important not to compromise on security, there are options available to suit different budgets. Consider the long-term value and benefits of investing in high-quality locks.

Enhancing French Door Security

Apart from selecting the right locks, there are additional measures you can take to enhance the security of your French doors.

1. Security Bars or Grilles

Security bars or grilles provide an extra layer of protection by preventing the door from being kicked in or forced open. They can be installed on the inside or outside of the door and are available in various designs to match your aesthetic preferences.

2. Window Films

Reinforce the glass panels of your French doors with security window films. These films are designed to hold shattered glass in place, making it difficult for intruders to gain access. 

Additionally, window films offer privacy benefits and can help regulate indoor temperatures.

3. Motion Sensor Lights

Installing motion sensor lights near your French doors can deter potential intruders. These lights are activated by movement, illuminating the area and alerting you to any suspicious activity. They provide an added layer of security, especially during nighttime hours.

4. Lock Maintenance and Care

To ensure the longevity and effectiveness of your chosen locks, proper maintenance is essential. Regularly lubricate the moving parts of the locks to prevent friction and ensure smooth operation. 

Keep the lock mechanism clean and free from debris. If you encounter any issues, address them promptly to avoid compromising your home’s security.


Choosing the best locks for your French doors involves a balance between security, aesthetics, and functionality. 

By understanding the various lock types available and considering factors such as security level, design, and ease of use, you can make an informed decision to protect your home and loved ones. 

Remember to explore additional security measures and practice proper lock maintenance to ensure your French doors remain a secure and stylish feature of your home.
