How To Fix A Window Lock In 10 Steps
It’s scary when a lock breaks on a window because intruders can easily use it to enter your home, whether you’re there or not. Nobody wants that, so we’re here to help you fix your window lock ASAP. When a window lock is worn, damaged, or loose, it’s best to replace it entirely.
Not doing so will increase your risk of not just break-ins but also humidity, which can lead to mold. Properly sealed windows are vital to keeping your home well-ventilated. Home repairs can seem daunting, but they’re not difficult if you have the tools and follow our handy step-by-step guide.
First of all, this guide assumes that your lock broke while the window is in the open position. If your window lock has been broken in a way that’s jammed the window shut, skip to the section below on fixing jammed windows.
Before we start, you’ll need to measure your window lock to ensure you get a compatible replacement lock.
4 Steps To Measure Your Window Lock:
Measure from the outer edge of the lock to the center of the handle to get your backset size. Standard backset sizes are 20 mm (millimeters) and 22 mm.
Measure from one end of the window lock faceplate to the other side to get the length. Common sizes include 400 mm, 600 mm, and 1,000 mm.
Alternatively, look on the lock faceplate for a manufacturer name and code. Letters in the code vary, but the numbers are typically the size of the lock.
Finally, measure the width of the lock. The most common size is 16 mm, but you will want one slightly wider if you have a metal or vinyl window frame.

What If The Window Lock Is Jammed?
If your window lock is broken in a way that has jammed your window shut, the process is much more laborious because you’ll have to replace the window seals. Doing so will void any warranties on the window, and you’ll risk damaging it. We recommend hiring a professional to do this if you’re not confident in your DIY skills.
If you’d rather do it yourself, we understand. You’ll need a few tools for the task.

Repairing a window lock secures your home from intruders, prevents air from escaping, and keeps your utility bills reasonable. In most cases, you can repair your window lock without paying a professional, but you must ensure your window’s manufacturer does not limit the types of repairs. Some window makers only honor warranties when their technicians repair their products.
