Windows might not be the first thing that comes to mind when you think of home security, but they’re one of the most common entry points for burglars. In fact, approximately 23% of break-ins occur through first-floor windows—often because they’re left unlocked or outfitted with inadequate locks. While many homeowners prioritize securing doors, ensuring your windows are properly protected is just as crucial to prevent unauthorized access.

Whether you live in a ground-floor apartment, a suburban home, or a high-rise condo, the right window lock can make all the difference in safeguarding your family and possessions. In this article, we’ll walk you through the best window lock options to help you choose the most effective solution for protecting your home.

Keyed Window Locks

Keyed window locks are one of the most secure and reliable options, especially for ground-level windows. As their name suggests, these locks require a key to operate, ensuring that only authorized individuals can open the window. This added layer of protection makes it nearly impossible for an intruder to force the window open without breaking the glass.

Ground-floor windows are the most vulnerable to break-ins, as they are easily accessible from the outside. Even if you live in an upper-level apartment, ground-level windows that open onto fire escapes or balconies can still be prime targets for burglars. Keyed locks provide a physical barrier that must be overcome, which is often enough to deter opportunistic criminals.

How Do Keyed Window Locks Work?

Keyed window locks typically consist of a lock mechanism installed on the window frame or sash, with a corresponding keyhole. The lock can be engaged and disengaged with the turn of a key, making it incredibly secure. Many homeowners use keyed locks as secondary security measures, in addition to the window’s built-in locking mechanism.

Keyed locks come in a variety of designs and materials, ranging from basic brass or stainless steel locks to more decorative options that blend seamlessly with the window’s aesthetic. They can be installed on nearly any type of window, including sliding, casement, and double-hung windows.

Advantages and Drawbacks

Advantages:

  • Provides excellent security, especially for ground-level windows.
  • Works well as an additional lock for added security.
  • Difficult for burglars to bypass without breaking the glass.

Drawbacks:

  • You need to keep track of the keys, which can be inconvenient.
  • If a fire or emergency occurs, searching for the key could delay escape.

Best for: Homeowners looking to secure ground-level windows or windows that provide easy access to fire escapes or balconies.

Sliding Window Locks

Sliding windows are popular in many homes due to their sleek design and easy operation. However, they are also more vulnerable to forced entry compared to other types of windows. Sliding windows move along a horizontal track, and if not properly secured, they can be lifted or forced off the track by determined intruders. This is where sliding window locks come in.

Sliding window locks are specifically designed to prevent the window from moving along the track, stopping burglars from gaining access. These locks are an excellent solution for homes with large sliding glass windows or doors, such as those leading to patios or balconies.

How Sliding Window Locks Work

Sliding window locks generally work by clamping onto the track, preventing the window from being opened or closed beyond a certain point. Some models are adjustable, allowing you to control how far the window can be opened for ventilation while still providing security.

Many sliding window locks are incredibly simple to install, making them a favorite among DIYers. You can find sliding window locks made of durable materials such as stainless steel or heavy-duty plastic, ensuring they can withstand repeated use and attempts at forced entry.

Pros and Cons of Sliding Window Locks

Advantages:

  • Effective at securing sliding windows and doors.
  • Allows for partial opening of windows for ventilation.
  • Easy to install and adjust as needed.

Drawbacks:

  • Can restrict how far the window can be opened for airflow.
  • May not be effective for preventing the window from being lifted off the track in all cases.

Best for: Homes with sliding glass windows or patio doors that need both security and ventilation.

Sash Locks

Sash locks are commonly used on traditional windows, particularly double-hung sash windows, where the top and bottom sections of the window slide up and down. These locks are typically installed on the meeting rail where the two sashes meet, securing both sections of the window in place.

Older window designs, particularly in historic homes, often have weaker or outdated locks. Sash locks provide an affordable and easy way to reinforce security without compromising the look or function of the window. While these locks may not offer the highest level of security available, they are still a strong deterrent for burglars.

How Sash Locks Work

Sash locks are installed directly onto the window frame and are usually engaged by turning a latch or rotating a lever. Once in place, the lock prevents both the upper and lower sashes from moving, ensuring the window remains closed. Sash locks can be combined with other forms of window security, such as window pin locks, for added protection.

These locks are often made of metal, providing a durable and long-lasting solution for securing your windows. Some modern sash locks feature enhanced designs that make it more difficult for intruders to tamper with them from the outside.

Advantages and Drawbacks

Advantages:

  • Simple, effective way to secure double-hung sash windows.
  • Easy to install and operate.
  • Maintains the traditional aesthetic of older windows.

Drawbacks:

  • May not offer the same level of security as modern locks.
  • Not suitable for windows that require partial opening for ventilation.

Best for: Homeowners with older, traditional windows who need to reinforce security without a complete window replacement.

Window Pin Locks

Window pin locks are among the simplest and most affordable security options available. They consist of a metal or plastic pin that can be inserted into a hole drilled into the window frame, preventing the window from being opened beyond a certain point.

Despite their simplicity, window pin locks are highly effective at securing both sliding and double-hung windows. They are a popular choice for homeowners looking for a cost-effective way to improve home security without investing in expensive lock systems.

How Window Pin Locks Work

To install a window pin lock, a small hole is drilled through the window frame and into the sash or sliding track. The pin is then inserted into the hole, preventing the window from moving. Many pin locks are adjustable, allowing you to choose how far the window can open for ventilation.

Window pin locks are typically made of metal and are easy to remove when you need to fully open the window. However, they provide a secure barrier that makes it difficult for burglars to force the window open.

Pros and Cons of Window Pin Locks

Advantages:

  • Highly affordable and simple to install.
  • Effective for securing both sliding and double-hung windows.
  • Allows for partial opening for ventilation.

Drawbacks:

  • Requires drilling into the window frame, which may not be suitable for all homeowners.
  • Not as convenient as other types of locks, since the pin must be manually inserted and removed.

Best for: Homeowners on a budget looking for a simple yet effective way to secure their windows.

Hinged Wedge Locks

Hinged wedge locks are a versatile option for homeowners who want to keep their windows open for ventilation while still maintaining security. These locks are designed to allow the window to open a few inches for airflow but prevent it from being opened wide enough for someone to enter.

This makes hinged wedge locks an excellent choice for homes in areas where fresh air is important, such as kitchens or bedrooms, without sacrificing safety. They work particularly well on double-hung windows but can also be used on sliding windows with the right setup.

How Hinged Wedge Locks Work

Hinged wedge locks are installed on the window frame, usually on the upper or lower sash. When engaged, the wedge blocks the window from moving past a certain point. However, it can be easily disengaged when you need to fully open the window.

These locks are often adjustable, allowing you to control how far the window opens. They are typically made of metal or durable plastic, ensuring they can withstand regular use without compromising security.

Pros and Cons of Hinged Wedge Locks

Advantages:

  • Provides both ventilation and security.
  • Easy to install and adjust as needed.
  • Ideal for homes where fresh air is a priority without sacrificing safety.

Drawbacks:

  • Not suitable for windows that need to open fully.
  • May not be as secure as keyed or pin locks in certain situations.

Best for: Homeowners looking for a balance between ventilation and security, especially in bedrooms and kitchens.

Smart Window Locks

Smart window locks represent the cutting edge of home security technology. These high-tech locks can be monitored and controlled remotely via smartphone apps, providing real-time updates on the status of your windows. They often integrate with broader home security systems, giving you full control over your home’s access points from anywhere.

In addition to remote control capabilities, many smart window locks are equipped with sensors that alert you if the window is tampered with or left open. This makes them ideal for homeowners who want the

convenience of modern technology combined with robust security.

How Smart Window Locks Work

Smart window locks are battery-operated devices that connect to your home’s Wi-Fi network. Once installed, you can lock or unlock your windows remotely through an app on your phone. Many models also include geofencing features, automatically locking your windows when you leave the house.

These locks are designed to be compatible with various types of windows, including casement, sliding, and double-hung windows. Installation is generally straightforward, but some systems may require professional setup, particularly if they are integrated with a home automation system.

Pros and Cons of Smart Window Locks

Advantages:

  • Allows remote control and monitoring via smartphone.
  • Provides real-time alerts if the window is tampered with.
  • Can be integrated with other smart home devices and security systems.

Drawbacks:

  • More expensive than traditional window locks.
  • Requires a reliable Wi-Fi connection and may need regular battery replacements.
