Home security is an essential part of the house. It’s useful for elderly and child safety and the protection of your properties.
These simple locks might be the only thing preventing burglars from coming to your home.
Whether you’re always out or always in…
You need locks. We can attest to that, being the outdoorsy people that we are.
So when we decided to install them, we tried different brands and products to find exactly what would appease our worries.
We tested each lock by measuring them, throwing them down and pounding on them, then installing them and trying to break into our own homes. And we didn’t just try them on sliding windows. We also tested them on sliding glass doors.

1 - Best Quality Window Security Lock - Editor’s Choice Award
Maxdot Adjustable Sliding Window Locks
- Manufacturer: Maxdot
- Material: Aluminum alloy and plastic
- Dimension: 5.83 x 4.33 x 1.38 inches
- Lock Type: Double lock; key lock
- No. of Pieces: 4
Bottom Line: No burglar can break in with this super-secure and sturdy double lock from Maxdot.
Pros
- Relatively affordable
- Durable material
- Rust-resistant
- Screws are tight
- Keys fit well
Cons
- Requires specific window specs
SUMMARY:
To use this lock, your window track height should be at least 1.5 cm, and the thickness is at most 1.6 cm. This product can’t accommodate beyond those numbers.
So lucky you if your window tracks are of the above-mentioned size!
Overall…
This lock’s quality exceeds other brands of the same price. It’s even better than some of the more expensive ones.
Once installed properly on your window frame – a very easy thing to do – it’s going to hold tight. The screws won’t loosen up as other locks do. And the keys are well-made too.
Both the lock itself and the key won’t rust quickly even when exposed to rain and sunlight. That’s our Editor’s Choice for you!
Moreover…
You’ll have four of these locks for a very affordable price.
We think that one lock is enough for the sliding windows. But for sliding doors, you might want to put two because they’re heavier.
But if you want to use more, why not? After all, you can’t compromise on home security.

2 - Best Budget Window Security Lock - Best Value Award
Defender Security U 9819 Sliding Window Security Lock
- Manufacturer: Prime-Line Products (Home Improvement)
- Material: Aluminum
- Dimension: 0.88 x 1 x 0.43 inches
- Lock Type: Keyed lock
- No. of Pieces: 1
Bottom Line: The U-9819 from Prime-Line proves that a high-quality secondary window lock doesn’t have to be expensive.
Pros
- Very affordable
- Great quality
- Durable build
- Rust-resistant
- Consistent size
- Keys fit properly
Cons
- Fits only a thin window frame
- Tends to damage your window
SUMMARY:
Even at first glance, you can see that this lock is durable. The material used for it is surprisingly high-quality, considering how cheap it is.
It won our Best Value award not because it’s the least expensive of all the locks we’ve tried. But it exceeded our expectations and even impressed us more than others.
Why so?
It’s a well-made lock in terms of cut and design.
We ordered a bunch of them and received locks of consistent sizes. The keys all fit properly too. However, you need to make sure that your window tracks are at most ⅛ of an inch thick.
But most importantly, we tried prying our sliding windows open and found that this lock would hold tight.
At first…
We thought that it could damage the window track.
But to install it properly, you’ll have to puncture your window frame – like fixed window locks. If you don’t mind doing that, then you won’t have any complaints at all.
And don’t worry about rain and shine because this lock won’t rust easily.

3 - Best Window Security Lock For Children - Top Pick Award
Lion Locks Sliding Window and Door Locks
- Manufacturer: Shop Square
- Material: Aluminum and vinyl
- Dimension: 7.01 x 5.31 x 1.85 inches
- Lock Type: Keyed
- No. of Pieces: 10
Bottom Line: This sliding door lock will keep your kids safe without hurting them.
Pros
- Very affordable
- Screws are vinyl-lined
- Child-proof
- Secure and durable
- Rust-resistant
- Can fit thick tracks
Cons
- Some screws are loose
- Creates noise
SUMMARY:
We didn’t realize how affordable this product was until we found ten high quality locks in the package.
But that’s not why it’s our Top Pick.
Why, indeed?
Since the screws have a vinyl lining, it’s safe for both the window track and the kids. It won’t damage anything or anyone while it provides a better grip on your frame.
So, even though it creates a bit of noise when in use, it’s a small price to pay.
Another thing we noticed was the inconsistency with the size. Generally, these locks would fit a 3/16-inch window track – even a ⅜-inch one if you don’t put the window seal in. But some locks are smaller than others.
However…
We didn’t mind it that much. As long as it secures your sliding window, all you’ll ever notice is its durability and sturdiness.
This aluminum lock is rust-resistant, even after exposure to window condensation and other elements. So overall, this lock is a steal!

4 - Best Adjustable Window Security Lock
2 Pack Sliding Window Security Locks with Keys
- Manufacturer: ALLWIN INC.
- Material: Aluminum alloy and silicon
- Dimension: 7.01 x 5.31 x 1.85 inches
- Lock Type: Keyed, wedge lock
- No. of Pieces: 2
Bottom Line: This adjustable lock will surely fit your window, no matter the size and thickness.
Pros
- It will fit most window sizes
- Excellent design
- Excellent grip
- Relatively affordable
Cons
- Inconsistent durability
- Has installation issues
SUMMARY:
We’re assuming we all know that not all windows are the same. Some have thick frames and tracks, while others have thin ones.
With this ALLWIN lock, that’s not a problem at all!
ALLWIN locks are adjustable.
You can use it on 0.39 to 2.36-inch sliding window tracks. So even if you’re unsure about your track size, no worries! This lock has got you covered.
And it’s even strong enough to secure sliding doors. It won’t rust, bend, or break easily. There are inconsistencies, though. If you compare the keys from the locks, you’ll find them less durable.
But in terms of securing the windows closed – or slightly ajar – there are no issues.
Moreover…
Its posh design makes it look classy. It would go with a minimalist and modern interior.
You’ll just need to double or triple-check that it’s installed properly. One of my friends complained that their kid could pry one out when they weren’t looking.
But once you get around that, this affordable lock will serve you well!
5 - Best Durable Window Security Lock
1 X Lot of 4 Pcs Sliding Window Lock
- Manufacturer: Momentum Brands
- Material: Aluminum alloy
- Dimension: 7 x 6 x 1.7 inches
- Lock Type: Keyed lock
- No. of Pieces: 12
Bottom Line: Burglars will give up on your sliding windows with this durable lock from Momentum Brands.
Pros
- Very affordable
- Sturdy and durable when installed
- Strong overall build
- Rust-resistant
- Easily installed
Cons
- Fits thin tracks and frames only
- Inconsistent size
SUMMARY:
Compared to other locks in the same price range, this isn’t the toughest and strongest one. But still, it’s a durable product that can keep you worry-free at night.
Once installed…
This lock won’t budge. It’s durable enough to hold both vertical and horizontal sliding windows. Plus, it has a tight grip.
It also helps that the lock is easily installed. It’s no rocket science, and if you have kids, they’d have the hardest time taking these locks out.
Although…
There are a few inconsistencies about the size. There are 12 locks in one pack, and sadly, some are smaller than the others.
It was a bummer because, in the first place, you could only use these locks with thin tracks. Now, we had a bunch of even smaller locks. We could’ve locked patio doors with them because they’re strong enough. But none of them fit.
Still, it’s a great buy.
This is a very affordable deal, and it did what locks are supposed to do. Moreover, it’s not going to rust in a long time.
6 - Best Material Window Security Lock
Window Locks, 4 Sets Premium Sliding Window Locks Security
- Manufacturer: MOTYYA
- Material: Aluminum alloy and plastic
- Dimension: 7 x 5 x 1.2 inches
- Lock Type: Keyed lock
- No. of Pieces: 4
Bottom Line: You can’t go wrong with a sliding window lock made of high-quality aluminum alloy.
Pros
- Affordable
- Rustproof
- Can accommodate thick tracks
- Safe for tracks
- Strong and tough material
- Durable and grips tightly
Cons
- Installation needs double-checking
- Not for the middle track
SUMMARY:
There’s a lot to love about this lock.
There’s the plastic gasket that keeps the screws from causing damage to the tracks. And the gasket helps keep the grip tight.
It’s also big enough to fit at least a 0.6-inch high and at the most 0.63-inch thick track. However, you can’t use it at the middle track because it’s a keyed lock.
Speaking of the keys…
This particular product uses a hex key, something that looks classy and isn’t too common. So that adds a little bit of security, knowing that there’s less chance that a burglar has another hex key to turn your lock.
And it’s very durable too. Not just the key but the whole lock. It’s made of high-quality, durable aluminum alloy, after all.
So it’s both strong and rust-resistant and will surely last long.
Only…
Be careful with the installation. Make sure to double or triple check it because the screws loosen up when not properly placed.
But once you get the hang of it, your sliding windows will have nothing to complain about.
7 - Best Window Security Lock For Family Protection
Reliancer 4 Pack Sliding Window Locks Sets
- Manufacturer: Reliancer
- Material: Stainless steel
- Dimension: 5.16 x 4.53 x 2.28 inches
- Lock Type: Keyed lock
- No. of Pieces: 4
Bottom Line: Let your whole household sleep better with these durable Reliancer locks keeping you safe.
Pros
- Adjustable
- Can accommodate thick tracks
- Great for child safety
- Firm and tight once installed
- Durable and sturdy material
- Uncommon keys
Cons
- Relatively expensive
- Slightly loose
- Slight difficulty in installation
SUMMARY:
We had high expectations from this lock because it’s a bit more expensive than others that impressed us. And we weren’t disappointed!
First…
Right off the package, these locks don’t look cheap at all. They even look more expensive than the actual price. It’s probably because of the smooth finish.
But it’s not all about the looks.
These locks are as strong as they look. Once we were able to install it properly, they didn’t budge at all. And we even let the little ones try to pry it out of place, but it didn’t move.
However…
It’s a bit difficult to fit the locks. They’re big, which is an advantage. And adjustable too. They can accommodate at least 0.48-inch high and at most 0.63-inch thick tracks.
The downside is that they loosen up when used with a thin and small window and door tracks.
But once you get the right lock placing…
You can worry less because it grips firmly and tightly. And it won’t rust that easily even when exposed to the elements.
It’s a plus too that the keys are unique.
8 - Best Easy Install Window Security Lock
Boao Set of 15 Siding Window Locks Door Locks
- Manufacturer: Boao
- Material: Aluminum alloy
- Dimension: 0.94 x 0.79 x 0.55 inches
- Lock Type: Keyed lock
- No. of Pieces: 15
Bottom Line: These Boao window locks made securing your sliding window easy and affordable.
Pros
- Very affordable
- Easy to install
- Rust-resistant
- Tight grip
- Safe for tracks
Cons
- Slightly less durable
- Fits only thin tracks
SUMMARY:
We found another super affordable yet good quality product. Boao will give you 15 durable and rust-resistant locks in one cheap package.
But the best thing about it…
Is that it’s so easy to install. It’s a no-brainer at all. You won’t need to use any tool except for the keys, and you’ll probably get it on the first try – we did. We think that it’s because it’s a small lock, so it grips tightly.
But the size can be a disadvantage too. You can’t use this lock if your tracks are thicker than 6mm or 0.23 inches. That’s too small for our taste.
Not to mention…
We were looking forward to installing these locks on our sliding windows. They’re slightly weaker than other products we tried, but they’re durable enough.
They still didn’t budge when we tested them. And they even proved to be safe for the tracks. There were no damages or punctures, even with our vinyl windows.
So we still recommend this lock for keeping your window at your desired opening.
9 - Best Window Security Lock For Horizontal & Vertical Windows
PRIME-LINE F 2588 Sash Lock
- Manufacturer: Prime-Line Products
- Material: Diecast zinc and baked-on enamel
- Dimension: 1.12 x 2.6 x 0.87 inches
- Lock Type: Latch
- No. of Pieces: 1
Bottom Line: This lock from Prime-Line Products is the best treat for your double-hung window.
Pros
- Fits most frames
- Suitable for aluminum, wood, or vinyl frame
- Strong and secure
- Good for different types of windows
- Safe for frames and tracks
Cons
- Relatively expensive
- Difficult to install
- Slightly loose grip
SUMMARY:
This lock isn’t the break-the-bank kind of expensive, but it costs more than most on this list. But for the best reasons, anyway.
It’s a fixed lock, so prepare to take out your tools. You’ll need some experience with screws and screwdrivers to install this lock properly.
But once that’s out of the way…
You can stop worrying about keeping your window completely closed. Don’t worry if your windows are wood, vinyl, or aluminum-framed. This lock won’t cause damage to anything.
Also, unlike track locks, this sash or latch lock isn’t just for sliding windows or doors. Prime Line’s F2588 will keep any type of window closed.
And it will hold strong enough.
When we tested the lock, it didn’t budge nor break. But after a few weeks, we noticed a bit of rust. And the screws loosened up because they were too small (the holes weren’t big enough.)
If you’re alright with replacing the screws every so often, then this lock is for you. It’s sturdy, generally strong and tough, and worth your money.
10 - Best Smooth Finish Window Security Lock
JEACENT A/C Security Window Lock Bar
- Manufacturer: Jaecent Innovations
- Material: Steel
- Dimension: 7.76 x 2.83 x 1.3 inches
- Lock Type: Hinged wedge lock
- No. of Pieces: 1
Bottom Line: This window lock would complete your interior design with its smooth and long-lasting finish.
Pros
- Adjustable length
- Smooth finish
- Durable and sturdy
- Strong material
- Rust-resistant
- Secure and tight
Cons
- Very expensive
- For wide tracks only
- Complicated installation
SUMMARY:
As far as window wedge locks go, this one from Jaecent is strong and tight. It’s made of steel that doesn’t rust, bend, or break easily.
We didn’t expect less since it’s one expensive lock.
Besides that…
It took us a moment to install the lock. Good thing it comes with instructions. But still, it’s not as easy as track locks or the likes.
And it’s about an inch thick. That means your track should be just as wide as that.
But once it’s installed…
This lock performs well enough.
It didn’t budge when we tried burglary on our own house, and since it’s a little different than our other locks, the kids didn’t even bother guessing how to untangle it.
It’s also a plus that it’s adjustable, so it would fit 10 to 17.5 inches window lengths.
And the best thing…
Is that it looks minimalistic and modern. It would go well with modern house interiors. Since the coating prevents rust, too, it’s both pretty and functional.

- Swivel action locks – makes use of a self-locking snib or a catch to secure the window.
- Window latches – usually used with single and double-hung windows, these locks make use of lever-like latches to lock the windows open or closed.
- Bar lock – often attached with a chain, the pin goes through one window sash to another to lock it close.
- Smart locks – electronic devices that use motion sensors, codes, and alarms to keep the house secure.
Features to look out for:
- The best locks are not just durable but also corrosion-resistant.
- If a lock is durable enough to secure patio doors, then all the more with windows.
