Frequently Asked Questions (FAQs)

1. What are the safest window locks?

Keyed locks are considered the safest window locks. They are more robust than latch locks and are often used in combination with latch locks for added security. Keyed locks are typically found on the side of the window and can be used on single and double hung windows, as well as sliding windows.

2. Can window locks be replaced?

Yes, window locks can be replaced. To replace them, you need to remove the old sash locks by drilling out the rivets that hold the locking mechanism in place. In most cases, you don't need to remove the keeper unless it is also broken. Then, you can set the new locking mechanism in place on the sash and secure it with pop rivets.

3. Are window locks effective?

Yes, window locks are highly effective in providing security. Keyed locks, in particular, are extremely secure as they require a key to unlock them. They are typically installed on the bottom of the window and secured to the frame. Keyed locks serve as an excellent deterrent since they are difficult to break through.

4. Do window locks stop burglars?

Window locks can help prevent burglars from gaining entry. They not only provide security but also act as a deterrent. Additionally, some window locks can also prevent children from opening windows from the inside, ensuring their safety and keeping intruders out.

5. Can you fix a broken window latch?

Fixing a broken or non-functioning window latch is relatively simple. All you need is a replacement latch keeper (preferably from the same window manufacturer), a putty knife or similar tool, a screwdriver, a hammer, and some patience. By following the proper steps, you can easily replace a broken window latch and restore its functionality.
