What are the different types of window locks?

All windows come with some kind of lock, and there are different types of locks depending on your window location and structure. Your windows may already have some of these locks, but adding more keeps your home secure from burglars or intruders.

Folding lock

Folding locks are the locks found embedded in the frames of casement windows. They are the standard lock that comes with casement windows when they are first purchased.

These locks keep window sashes locked when they are turned down. The window is unlocked when the lock is turned up.

Window wedge

There are several varieties of window wedge locks. Some are attached to windows using velcro and can be adjusted, while others can slide up and down to fit the window.

Window wedges are a good option to stop windows from opening more than you want. If you decide you want the window opened more than you originally thought, you can adjust the window wedge from the inside.

Sliding window locks

If you’re looking for affordable locks, sliding window locks are an inexpensive DIY option available at most hardware stores. They are movable metal pins that screw into the sliding tracks of windows.

Sliding window locks also prevent windows from opening any more than you want them to. They can be easily moved from window to window if you need to switch them out.

Keyed locks

The name gives it away—keyed locks require a key to lock and release. They are typically found on the sides of windows, and they work best on single-hung, double-hung, and sliding windows.

These locks are sturdier than latch locks, another common window lock. Keyed locks are often paired with latches for more security.

Window pin locks

If your home has casement windows, window pin locks are another one of your options. They act like mini door chain locks for your windows.

One part of the lock is attached to the window frame, the other is attached to the sash, and they are connected by a chain or cable that keeps the window from opening too wide. Window pin locks are easy to install, but you will need a drill for both attachment sites.

Latches

Latches are simple, standard locks found on single- and double-hung windows. It connects both of the window’s sashes to stop them from moving.

The sashes are held in place and “locked” with latches, but this is not the strongest lock. It’s recommended to add additional locks to windows that only have latches.

Key Takeaway Window locks secure your windows against intruders, and you can add more than one to each window for added security.

What is the safest kind of window lock?

The American National Standard Institute (ANSI) has established lock grades to compare the security of locks. When you’re deciding on what locks you want for your home, watch for these rankings:

Grade 1: highly secure locks, some of the best on the market

Grade 2: intermediate

Grade 3: basic, least secure locks

Keep in mind that the lower the lock grade, the higher the price. All things considered, the safest lock is a lock that properly fits and functions with your window.

FAQs

Why are window locks important?

Window locks secure your windows to keep you, your family, and your property safe from intruders. Aftermarket locks can help give you extra peace of mind.

What type of lock is used on a typical window?

Windows are not one size fits all—so not all locks will work on all kinds of windows. “Typical” windows can often have more than one type of lock too. The locks you use will depend on the kinds of windows you have in your home and what locks will fit them.
