Types of Window Locks
Keyed Window locks
These are often used to secure double-hung windows. They are installed on the side of your window and will secure it to its frame. It is important to keep the key that these locks require secured at a place and not lose it.
Window latches for additional security.
These are often seen on locks for single and double-hung windows that are not made of standard UPVC. With window latches, you can expect to be installed on the top of a window sash. As well as providing a layer of security, they can also stop heat from escaping from your windows and create a seal to keep the cold out.
Child safety window latches
These only open at a certain degree, preventing windows from being fully open. This is great to keep your home ventilated without the risk of your children accidentally falling out.
Sliding window lock
As the name indicates, this type of lock is for sliding windows. The lock, which can come in a bar, a sash, or a wedge, is installed on the track to prevent the window from being opened.
Window Push-lock
A push-lock is a kind of lock installed on sliding, awning, and double-hung windows. A locking bolt can be pushed to lock and opened with a key.
Window pin lock
A window pin lock is a type of lock that uses two separate parts; one installed on the window itself and one on the window frame.
Smart Window Lock Sensors
Instead of a key, Smart locks require a code, or you can also open them using your smartphone. While you will most often find smart locks on front and back doors, sensors exist for windows. Sensors can tell you if your window is locked or unlocked, closed or open, allowing you to monitor the safety of your home.
Ventilating Window Locks
A ventilating lock is installed above the sash on the window frame. It has a moveable pin that prevents it from opening all the way when placed above the window. If the pin is pushed aside, the window can open fully.
Hinged Wedge Window Locks
A hinged wedge lock prevents a double-hung window from opening. If installed directly above the sash, it can keep a closed window from opening until you push the lock inward to allow the window to open fully. If placed higher on the window frame, the window can be opened partially but without the ability to open it further unless the lock is pushed inward.

Common Questions About The Different Types of Window Locks
What are window pin locks?
Pin Locks are large pins that fit in a window frame to hold it closed. They work with single-hung, double-hung, and slider-type windows. All you need to install a pin lock is a drill and some screws.
How do you stop a window from opening all the way?
You can achieve this by installing a chain lock (the same type used on doors) to limit the distance the window will open. For maximum security, fasten it to the sash and frame with the longest screws that the window will accommodate. For additional protection, install a keyed lock along the sash rail.
Can uPVC window locks be replaced?
It is sometimes possible to replace the malfunctioning handle and lock with an exact match, so it’s always best to have the old one with you when looking for a replacement. The lock and handle must be removed first, so make sure the window is closed and the handle should lift off.
How do I open windows with sidelocks?
- Find out if the window is open and push it with your hands. If this doesn’t work, place a prybar between the window and the windowsill. Jiggle the window a little, and it will move and be able to slide or come off. But this procedure might not work if you are latched.
- Put the blade of a thin hacksaw in the window close to the latch. But this method only works if you put the blade between the window sashes and flip the lock.
- Another way to open a locked sliding window is to break the lock. This process may sound extreme, but that is a great way to go, except you don’t want to damage your window. You can choose to use a prybar on the latch and force the window open.
Why are window locks important?
Window locks are an important safety feature. Their main job is to help keep intruders from entering your home.
These become even more relevant if young children live in your home; windows must always be locked. The right window locks will also make you eligible for home insurance.
Do all windows need locks?
It’s totally up to you; you may decide that windows in second-story bedrooms do not need a lock; however, certain areas need window locks without a doubt. Your basement, front windows, and any windows on the first level that aren’t protected by a fence should definitely have window locks. Otherwise, these become easy targets for burglars.
