Which Is The Best Window Locks For Wooden Windows?

Adding a lock to your wooden window adds an extra layer of security. It may not stop a determined burglar but it will deter most of them.

The best window lock depends mostly on the level of security you need. A barn window will do with a cheap lock while your house windows require stronger locks.

If you are looking for a restrictor lock to keep your kids and pets safe, there are several good ones to choose from including child safety locks and window stay locks.

In this buying guide, we recommend the top five window locks for wooden windows. These locks work on all types of wood frame and timber casement windows.

Key Considerations

Here’s what to consider when choosing the best window locks for your wooden windows.

A. Type of Lock

Not all window locks work on wooden windows. So check that the lock you are about to buy can be installed on a wood casement window.

The most common type of lock for wooden windows is a pin lock or a screw lock. It consists of two parts, one that’s installed on the window frame and the other that is installed on the window itself. When you close the window and turn the key, a pin or screw locking mechanism secures the window.

Another type of window lock is called a stay lock. A window stay lock locks the window open. It allows you to open your window and lock it at a specific position.

You can keep a window open but not wide enough for a burglar to get in. This is handy if you want to let some air in at night or in case you forget to close the windows when you go out.

It’s also helpful if you are using a vented appliance such as a portable air conditioner or a tumble dryer. You can pass the vent hose through the window without giving a burglar easy access to your home.

A window stay lock replaces the standard stay pin on your window frame. You can then use the included key to open or lock the pin.

Another lock option for wooden windows is a child safety lock, sometimes called a window restrictor. A child safety lock has nothing to do with security; rather, it protects kids from falling out of the window.

The lock prevents the window from opening more than a few inches, ensuring kids don’t climb out of the window. This is especially handy for windows on upper floors.

A window restrictor can also ensure kids don’t throw large objects out of the window and potentially injure someone below.

B. Quality and Materials

A stainless steel window lock will cost you more but it’s one of the most secure type of lock you can get. Not only is it resistant to cutting, it also withstands moist environments without rusting.

Cheaper window locks are made from weaker materials like brass or zinc alloy. These are ideal for low-security situations such as a barn or greenhouse window.

As for child safety locks, most of them are made from plastic since they are not used for security.

C. Fit and Ease of Installation

Check the window size requirements for the lock before you order. Most manufacturers will specify a minimum window frame width for successful lock installation.

As you check the size requirements, also check if the window lock is designed for DIY installation. Most window locks are, which saves you money since you don’t need to hire a pro.

Most locks require basic tools including a drill and pencil. Everything else, including the screws, is typically included with the lock.

Best Window Locks for Wooden Windows: Reviews

1. Yale V-8K101-4-BR Pivoted Window Lock, Pack of 4

The Yale V-8K101-4-BR window lock is the best choice for situations that require a high level of security. They are ideal for house windows.

The package includes four set of locks, each with its own key. So you can install locks on four windows or, if you want more security, install multiple locks on each window (e.g. two locks per window).

The Yale locks are easy to install. Use the lock itself to drill holes in the right places then use the included screws to secure the two parts of the lock onto the window and the window frame.

These locks are not just good for security; they also make your home more energy efficient. When you close the window and turn the lock, it draws the window even tighter against the frame.

This prevents cold draughts from getting in and reduces heat loss.

What we like about it:

  • Pack of 4 – ideal for multiple windows.
  • Improves home security.
  • Easy DIY installation.
  • Improves home energy efficiency.

2. Yale P-2P113-WE-2 Security Lock, Pack of 2

The Yale P-2P113-WE-2 lock is another good choice for securing windows from the inside. It works pretty much the same way as the Yale V-8K101-4-BR lock above.

Each lock consists of two parts. The lock goes on the window and the strike plate goes on the window frame. Once you close the window, you just turn the key. A screw turns and attaches the two metal parts securely, preventing the window from being easily forced open.

The Yale P-2P113-WE-2 lock is made with steel so it’s ideal for use inside your home. You can also use it to lock barn, shed or greenhouse windows.

The package includes two locks and two keys.

What we like about it:

  • Secure.
  • Easy to install.
  • Adds an extra layer of security.
  • Beautiful white finishing.

3. BeeGo Window Restrictor Child Safety Lock

BeeGo Window Restrictor Child Safety Locks

If you have young kids around, we recommend a window restrictor. This one by BeeGo is super easy to install. It doesn’t require any drilling or screws. Instead, it attaches to the frame and window using strong adhesive.

And when you need to remove it, it doesn’t leave any damage behind. This makes BeeGo ideal for all homes including rentals.

The BeeGo window restrictor consists of two parts: a locking plate that you attach to the window frame and the sliding lock that attaches to the bottom of the window. You can also install the lock and plate at the top of the window if you want it out of reach of kids.

The adhesive at the back of these two parts is strong. It can withstand a weight of up to 30kg, so don’t worry that your kids will pry it open.

Once you install the restrictor, open the window until the lock clicks into place. The window will stay in that position until you close it.

With the lock in use, you won’t be able to open the window all the way, which is the point. But if you’d like more fresh air, it’s easy to disengage the lock and open the window wider.

By the way, installing the BeeGo window restrictor doesn’t mean you cannot use a traditional window lock. If you are worried about your kids falling out as well as burglars getting in, you can install both the restrictor and one of the Yale window locks.

What we like about it:

  • Easy to install – no drilling required.
  • Strong adhesive.
  • Can be unlocked to allow full window opening.

4. Merriway BH03441 Security Window Stay Lock

A window stay lock is a good alternative to a window restrictor if you already have a window stay. It does the same thing as a restrictor – restricting the window from opening beyond a few inches.

A window stay lock works like a normal window stay pin, with the difference being that it’s lockable. So once you set the stay where you want, no one can move it. Kids or burglars can’t force the window open wider.

The Merriway BH03441 is the best choice for anyone looking for a good quality window stay lock. It’s a pack of two, so you can install them on two windows.

It’s easy to install though you’ll need a drill. Remove one of the existing stay pins on your window frame and install this pin in its place.

To lock the window stay, first set the window to your preferred opening size and secure the stay with the pin. Put the lock over the pin and lock it with the included key.

Do not leave the key in the lock, otherwise it’ll defeat the purpose of the stay lock.

What we like about it:

  • Easy to install.
  • Ideal for keeping kids safe and burglars out.
  • Low price.

5. Sterling LWL101 Hinged Wooden Window Lock

If the two Yale locks above are not what you are looking for, the Sterling LWL101 is a good alternative. It’s designed specifically for use on hinged wooden windows and comes with the screws you need to install it.

Similar to the Yale Locks, the Sterling LWL101 is not just good for securing your windows; it also improves energy efficiency by keeping out cold draughts and preventing heat loss.

What we like about it:

  • Improves home security.
  • Reduces heat loss.
  • Easy to install.
