Window locks come in a variety of forms. They can be as simple as latches or bolts attached to the window frame to more complex systems that latch onto the sash and lock from inside the window. Some manufacturers even offer technology like anti-pry bars and keyed locks for optimal security, but does this mean that all window locks are impervious to break-ins?

1. How Secure Is This Window Latch?

Today we’re looking at an essential latch that screws can attach to the window frame. The only difference between this window lock and a regular hinged door is that the window lock can’t be opened from the outside, so break-ins are impossible. All you have to do is screw your new lock into place, and you’ll be secure as long as there’s no one trying to take your stuff.

It is important to note that the latch in our example is rated for ten pounds, which makes it ideal for use with older windows that might have a little less spring power. For best results, we recommend using this type of window lock on top of an external steel frame, which will provide the rigidity needed to keep your window from opening.

2. How Secure Is A Window Bolt Lock?

Another simple form of window security is the window bolt lock. It’s a giant screw that you can add to the top of your window frame and then tighten down until it’s completely locked in place. You can get different types of window bolts that offer various levels of security, but all in all, this is another simple product that should be a staple for every home or business owner.

3. How secure is this window lock?

This is a simple keyed lock that can be found in the window of many homes and businesses, although it’s seen less often than the two types of locks we looked at above. A keyed window lock can offer excellent security if you need to be able to lock your window from the inside, but it still relies on a locking mechanism that someone could break through.

It doesn’t sound like the best option for many consumers, which is probably why it’s not quite as popular as the other types of window locks we looked at. Still, if you want something that offers good security and can still be opened from the inside if you need to get in and out quickly, check out some of these keyed locks.

So, with all of that said, are all window locks safe from break-ins? We’re not sure how many people will be breaking into windows to prove us wrong, but we’re confident they can. There are certainly a few more break-in-proof locks out there for the truly paranoid, but the three examples we looked at today are entirely workable for most people.
