Types of Home Window Locks
When we think of keeping our homes safe, we think of strong front doors and deadbolts, alarm systems, cameras, and security lights. But windows? They don’t always get the same level of attention, even though they can also be the easiest way for someone unwanted to get in.
That’s where good window locks come in.
At Hawkeye Windows, we’ve seen that windows are not just for seeing outside or letting in light, they’re also a big part of your home’s safety. A strong frame and good glass matter, but it always feels better knowing your windows are locked up tight.
So, let’s talk look at the different window locks out there, what makes them different, and how to choose the best ones for your home.
1. Sash Locks

Sash locks might not look fancy, but they do their job well. A sash lock is a small mechanism usually found at the meeting rails of double-hung or sash windows. When you turn the latch, it pulls the two sashes tightly together, helping to keep the window closed and secure.
They’re great because they don’t stand out too much, but they still help keep warm air in during winter, cool air in during summer, and unwanted guests out all year round. You can find them in different finishes — like brushed nickel, black, or brass — so you can pick one that actually looks nice on your window.
It’s a small thing, but sometimes those small things make a big difference.
2. Keyed Locks

These need an actual key to open. Even if someone manages to slide your window open from the outside, they’re not getting far.
They’re especially handy for ground-floor windows or basement windows, where someone might be more tempted to try their luck. They’re also great if you’re going to be away for long trips, just for that extra bit of reassurance.
They’re simple, affordable, and tough. You can’t really go wrong with that combo.
3. Vent Locks
Vent locks let you crack your window open just a few inches without fully unlocking it. These are awesome if you like a bit of air circulation without sacrificing safety.
They’re small, smart, and super convenient.
4. Sliding Window Locks
Sliding windows are gorgeous and modern, but they can be a little more vulnerable when it comes to security. That’s where sliding window locks come in.
These sit right in the track of your window and prevent it from sliding open past a certain point, or at all, depending on the style. Some use a pin, others use a clamp-style design that’s easy to move or remove when needed.
If you’re renting, these are perfect — no drilling, no permanent marks, just a quick fix for peace of mind.
We often recommend them for homes with wide glass panels or patio-style windows. They’re subtle, effective, and don’t mess with your window’s appearance.
5. Latch Locks
You’ll find latch locks on a ton of standard windows — single-hung, double-hung, casement, you name it. They’re the little levers that click into place, keeping your window sealed shut.
They’re easy to use, they last a long time, and they don’t cost much. If you combine them with another type of lock (like a keyed lock), you’ve got yourself a pretty strong setup.
6. Folding Locks (Also Called Hinged Wedge Locks)
These are a favorite for people with double-hung windows. Folding locks (or hinged wedge locks) sit on the window sash and can be folded in or out depending on how much you want your window to open.
Fold it out, and the window can only move a few inches. Fold it back in, and it opens like normal.
They’re perfect if you’ve got kids or pets at home and want a little extra safety without giving up fresh air.
7. Smart Window Locks
If you’re into smart home tech, this one’s for you. Smart window locks are a newer option that’s becoming really popular.
They connect to your home’s Wi-Fi or security system, so you can check if your windows are locked from your phone, get alerts if one is opened unexpectedly — which is especially great when you’re away from home.
They’re more expensive than regular locks, but if you like convenience and peace of mind, they’re worth it.
Which Type of Window Lock Do You Need?
The “right” lock really depends on your home and your lifestyle.
If your windows are on the ground floor, go for something strong — keyed or sliding locks.
If you like fresh air but want security, vent or folding locks are perfect.
If you’re all about tech, you’ll love smart locks.
And if you just want something simple yet also classic? Then, sash or latch locks get the job done.
At Hawkeye Windows, we can help you figure out which ones work best in your home, based on how you use your windows every day. There’s no one-size-fits-all answer — and that’s kind of the point.
Why Window Locks Matter (More Than You Think)
It’s easy to overlook window locks until you really need them. Break-ins don’t just happen through front doors or smashed glass. They happen through unlocked or weakly locked windows.
