Window Locks: Which Are the Safest?

Learn about the differences in window locks, including traditional window latches seen here.

When selecting the hardware for your home windows, you must consider which locks you prefer. Your window locks are more than merely decorative or convenient for closing up windows on chilly days. Locks also play a role in keeping your family safe from intruders. While not every window needs a high-safety lock – second-story windows with no outside access point will need less security – some windows need extra protection. For example, any basement, first-floor, and large windows that someone can fit through should have high-quality and secure locks. 


A window latch is the standard lock found on double and single-hung windows. The simple mechanism connects the two sashes of the window and prevents either side from moving. Latches hold the sashes in place, “locking” the windows, but the sashes themselves are not a robust window lock. This should not be the only on your windows at home if you are concerned about preventing break-ins. 

Folding Lock

Folding locks are found in casement window frames. When turned down, the folding locks keep the sashes locked. When turned up, the lock is released. 

Window Pin Lock

Window pin locks are akin to chain locks on doors. One part of the lock attaches to the sash, while the other is attached to the frame. The parts are connected by a cable or chain that prevents the window from opening wide. These locks are easy to install but require a drill to attach the two ends. They are one of a few locks that can be used on casement windows.

Window Wedge

Window wedges come in various forms. Some slide up and down, others are attached with Velcro and can be adjusted. Wedges are put into place to prevent the window from opening more than you desire. If the window must be opened more, you can adjust from the inside. 

Keyed Locks

These window locks require a key to open and close the window. These are more secure than latch locks alone and are often paired with latch locks to offer maximum protection. Keyed locks are placed on the side of the window and work on sliding windows and single and double-hung windows. 

Sliding Window Locks

Sliding window locks consist of movable pins that screw into the sliding window track. This stops the window from opening more than the desired amount. These inexpensive locks are easy to use and can be moved from one window to another as needed.
