How To Fix A Window Lock In 10 Steps
It’s scary when a lock breaks on a window because intruders can very easily use that as a way to enter your home, whether you’re there or not. Nobody wants that, so we’re here to help you fix that window lock ASAP.
When a window lock is worn, damaged, or loose, it’s best to completely replace it. 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 repair can sound like a daunting task, but it’s not terribly difficult if you have some basic tools and follow our handy step-by-step guide. Let’s dive into what you need and what to do.
First of all, this guide assumes that your lock broke while the window is in the open position. If your window lock has broken in a way that’s jammed the window shut, skip down to the section below on fixing jammed windows.
Before we get started, you’ll need to measure your window lock to ensure you get a suitably compatible replacement lock.
To Measure Your Window Lock:
Measure from the outer edge of the lock to the center of the handle to get your backset size. Common backset sizes are 20 mm (millimeters) and 22 mm.
Measure from one end of the window lock faceplate to the other side to get your lock length. Common sizes include 400 mm, 600 mm, and 1000 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 quite a bit more laborious because you’ll have to fiddle with your window seals. Doing so will void any warranties on the window, and you risk damaging it. We would recommend hiring a professional to do this if you’re not absolutely confident in your DIY skills.
If you’d rather do it yourself, we understand. You’ll need a few tools to aid the task.
