7 Popular Types of Window Locks for Homes

You may think, “What’s the point of knowing the types of window locks? If intruders really want entrance inside our house, can’t they just break the window or go through the front door?”

We’re all concerned about the security of our home. Remember, intruders will want to get inside your home and then out as quietly as possible, without anyone knowing. Breaking a window (or even worse, going through the front door) will alert you, your neighbours, and thereby the police.

Knowing the different types of window locks and choosing the best lock for your home can help you prepare for anything. Your goal should be to make the intruders’ entry as difficult as possible.

Types of Window Locks

Window locks aren’t just about security. They act as a multi-layered defence that safeguards your home from intruders and harsh weather and even keep curious little ones safely indoors.  

Pair these essential safeguards with durable windows and doors, and you basically have a fortress of comfort and peace of mind.

Sash Locks

Sash locks combine both a latch and a locking mechanism, making them ideal for single-hung and double-hung windows where panels slide up and down. These locks connect one sash to another, securing them in place. One type is a swivel action lock with a nib that locks in place when turned from left to right.

They’re best suited for windows made from wood or vinyl, as they can be easily mounted without damaging the frame. Metal windows can accommodate window sash locks as well, though they may require special screws or fittings for a secure installation.

Sliding Window Locks

Sliding window locks are designed to secure windows that slide horizontally or vertically. These locks anchor the moving part of the window to the frame, preventing it from being opened from the outside. 

These locks are typically small and unobtrusive. They have a latch mechanism that clamps onto the window track after the window pane and a thumb screw that secures it in place when tightened.

Keyed Locks

A keyed lock adds an extra layer of security by requiring a key to open or close the window. This lock typically features a locking mechanism that engages with a key, much like traditional door locks. To operate, you simply insert the key, turn it to lock or unlock, and remove the key to keep the window secure.

Keyed locks are versatile and can be used on any window type, including double-hung, sliding, and casement windows. They are particularly useful for windows on the ground level and the basement — areas in your home vulnerable to intruders and need extra security.

Window Pin Locks

Window pin locks are like chain locks for doors — one side is drilled and locked into the window frame while the loose end (the “pin”) can be inserted into the window sash. Inserting the pin into the window sash locks the two window parts together, making it inoperable from the outside. The pin is typically made of metal and can be easily removed and stored when not in use.

A window pin lock is particularly effective on sliding and double-hung windows where the sash moves vertically or horizontally. For sliding windows, the pin goes through the frame and the sliding part to prevent it from moving. In double-hung windows, the pin locks the lower sash into the upper one to make it unopenable.

Casement Locks

Window locks for casement windows and awning windows are called casement locks that are integrated into the window frame. They consist of a lever or handle that, when turned, activates a metal hook mechanism that engages with the frame and locks the window securely in place.

Casement locks are ideal for windows placed in areas with high wind pressures because the lock’s design ensures that the window is securely shut and will not swing open.

Hinged Wedge Locks

Hinged wedge locks are designed to limit how far a hung or sliding window can open. It’s made of a wedge that has a hinged mechanism screwed to the window frame. When swung in, it blocks windows from opening further. When swung out, it allows them to open fully. 

Hinged wedge locks are particularly useful for maintaining ventilation while ensuring safety, as they allow the window to remain partially open yet secure. This type of lock is user-friendly — operating the lock is as simple as flipping the wedge into position.

Child Safety Window Locks

Child safety locks are specifically designed to keep young children safe by preventing windows from opening beyond a preset limit. These locks typically involve a mechanism that attaches to the window frame or the rail, which allows the window to open only up to four inches — enough for air circulation but not enough for a child to climb.

Child safety latches are versatile and can be used on any window type. They’re often used in upper-story rooms where open windows pose a significant risk.

Do All Rooms Need Window Locks?

Ideally, all rooms in a house should have window latches. However, we recommend that ground-level and basement window locks be sturdier than the other locks in your home since these can be entry points for intruders. Windows large enough for a person to fit through as well as children’s rooms should also have solid window locks for solid security. You can mix one or more of these locks for additional protection.
