How to Secure a Window With a Broken Lock ?

Window bars/grillesThe simplest and most effective security option for windows are tough metal bars/grilles. People sometimes avoid them due to appearance, but there are obviously some very nice choices like the ones shown in the photo above.
Unless the criminal is able to pull the bars off or cut through them, it will be impossible to even reach the window, let alone check if the lock is working or not. Which makes having or not having a lock pretty much irrelevant with a good set of metal grilles on top.
However, in case the bars get removed or cut through you'll still want some other locking mechanism in place, like a window barricade.
Window barricades (for sliding windows)There are many ways to lock a window without a standard lock. The easiest option is to barricade it from the inside. This is a really effective solution for sliding windows, especially horizontally sliding ones. But it can also work with some vertically sliding windows, depending on the design.
You can use a simple window/door security bar to block the sliding window panel from moving.
Or you can use the Burglar Bar which is super affordable and works in the same way. Both are simple and effective options that require no installation. They're also great travel companions that you can use to secure any sliding window.
