Securing Your Sliding Glass Door from the Outside: Comprehensive Guide

Ensuring the security of your home is a top priority, especially when it comes to sliding glass doors. Commonly found with a handle only inside, these doors often present a challenge when you need to secure them from the outside. This guide explores various methods to lock or close a sliding glass door from an external position.

Understanding the Problem

Sliding glass doors are popular for their ease of use and modern aesthetic. However, their operability from one side only can be a security concern. If you find yourself in this situation, fear not, as there are effective solutions to secure your sliding glass door from the outside.

Sliding Door Locking Mechanism

Some sliding doors are equipped with a built-in locking mechanism designed to engage from the inside. This system typically requires the door to be closed fully before it can be locked securely. If your door has this feature, you’re one step closer to securing your entry point.

Additional Locking Solutions

In the absence of a built-in locking mechanism, you can consider adding external locking devices, such as:

Security Bar

A security bar is a simple yet effective solution. It slides into the track of the sliding door and prevents it from opening. This method is widely used and provides peace of mind without requiring significant installation work. However, ensure that the bar is properly aligned and secured to prevent unauthorized removal.

Surface-Mounted Lock

For a more permanent solution, you can install a surface-mounted lock on the frame of the door that can be accessed from the outside. This option requires drilling into the frame, which may necessitate professional installation. The surface-mount lock provides a secure way to lock the door while maintaining the sleek appearance of the sliding door.

Keyed Lock

Another option is to fit a keyed lock that allows you to lock the door from the outside. This can be particularly useful for adding an extra layer of security, especially if you frequently leave the door open for convenience. Professional installation may be required, and you may need to consult a locksmith to ensure the lock functions correctly.

Temporary Solutions

For a quick and easy solution, you can use a wedge or block to secure the sliding door temporarily. This method involves placing a wedge in the track to prevent the door from sliding open. While this is a temporary fix, it can be particularly useful in emergency situations or when you need a quick solution. However, it is not a suitable long-term security measure.

Security Film

Although it does not lock the door, applying security film to the glass can significantly enhance the door’s security. Security film is designed to make the glass harder to break, providing an additional layer of protection. This solution is cost-effective and easy to install, and it can keep potential intruders at bay.

Considerations and Compliance

When making modifications to your sliding glass door, ensure that any changes comply with local building codes. Additionally, check if the modifications void any existing warranties. It is wise to consult a professional to ensure that the installation is done correctly and meets all safety standards.

Purchasing Latch Locks for External Securing

To install a latch lock on the outside of the frame, look for a latch lock that hooks into the frame. Ensure that the lock can be accessed from the outside to provide security when the door is closed. There are also lock mechanisms that can be used in conjunction with the inside thumb lock for added security.

Locking from the Inside When No Handle Exists

If your door lacks a handle that can be locked from the inside, you have several options. One effective solution is to buy or improvise a Charlie Bar, a simple yet effective locking mechanism. A Charlie Bar is a bar that can be placed in the track to prevent the door from opening, offering a quick and easy solution.

Consulting a Locksmith

When all else fails, consult a local locksmith. They can modify your existing lock to allow you to lock the door from the outside. As a locksmith myself, I can assure you that it is a straightforward process that can be completed within a few hours. Bring a photo of the door’s current locking mechanism to your local locksmith, and they can provide you with the best solution for your specific needs.

Securing your sliding glass door from the outside is crucial for maintaining the safety of your home. By understanding the options available and taking appropriate measures, you can ensure that your sliding glass door is as secure as possible.
