Description
Curious kids try to explore everywhere, but the Safety 1st OutSmart Lever Handle Lock helps you keep them safer with the first ever decoy button. Your child will think the decoy button will let them open the door, but pushing it has no effect. You’ll know that the surface on the sides hides the actual secret to opening the door. The Lever Lock is a clever way to prevent your little explorer from accessing off-limit rooms. It installs easily and can be operated by an adult with a squeeze on the hidden buttons built into the hinge. The decoy button won’t do anything when pushed, but adults in the know can easily open the door. In side by side comparisons with leading competitors using real life toddlers, the Safety 1st OutSmart Lever Handle Lock was strong enough to keep even the cleverest of toddlers out. Even in lab testing using state of the art mechanical pull force equipment, Safety 1st outperformed the competition.

I actually bought this item not as a childproof lock, but as a "fake" door lock, and it worked perfectly! To clarify, I went on a long-term vacation and had a pet sitter (who I hadn't worked with before) visiting my place every other day to take care of my pets, and I wanted a deterrent to put on my bedroom door (lots of valuables in my closet and I didn't want to think about it) on the off chance that this person was shady in any way. This was a great option that didn't involve actual locking, but at least gave off the image that the room was not accessible. The fact that it has a decoy "button" that doesn't work is a plus so it can be at least a little confusing even for adults. **IMPORTANT NOTES: Do NOT leave the lock even slightly engaged (in the locked position) if you are on the other side of the door (AKA the opposite side/room of where the lock is placed). You'd be putting yourself at risk for accidentally locking yourself in a room (because the door handle will not be able to turn all the way on the way out, effectively making the door nearly impossible to open), and if you live alone and happen to lock yourself in without your phone and in a room without windows... you're kind of screwed unless someone comes to find you lol. It's something I realized as I was going in and out of the door this was installed on, so PLEASE take care not to do that. The biggest caveat here is that removal is a little bit of a pain, and because of it, the lock isn't necessarily reusable without some kind of reapplication of adhesive. Because the adhesive is so strong (which is what makes this lock appealing in the first place), you have to heat up the bottom of the lock with a hair dryer and then use either a butter knife (so you don't scratch your door; anything sharper would be risky) or a long, strong piece of dental floss to pull it off the door. I was able to get it off without issue (no damage or significant residue), but it did take a decent amount of effort and muscle to get it off, probably 15-20 mins altogether. All in all, the locking mechanism is really great and does its job perfectly, but be aware that removal will not be extremely easy.

“5-stars? Really? Why?” I’m going to get into that in a moment. I honestly held off offering these things for a hot minute because of what Amazon reviewers were saying about this product and was also mulling over the cheaper lever lock too. First, let me say this: The design of this product was very carefully thought out and executed. Most of the problems that exist in these reviews have to do with the construction and operation of the lever handles themselves and not the child safety lock. Specifically, if the latch is engaged, people on the other side of the door may not be able to get the out as many door handles work in unison from both sides (eg: cranking the lever on one side also cranks on the other). So owning and using these requires a very attentive and alert authority figure to ensure no one gets locked in a room. Another thing I’ve read is how people wished that Safety 1st would more easily allow the lock to engage again after closing a door. For that, let me refer anyone reading the last point I made of someone being locked in a room. Let me give an example: If you, the authority figure, are doing some chores around the house and enter a room while the little one is running around, imagine the child shut the door and push up on the lever lock to engage it WITHOUT pressing the release buttons. If a lock engaged itself like that so easily, a parent, grandparent, or sitter would be locked inside of a room. So it’s just as essential to press the release buttons to engage the lock as it is to disengage. That’s just one example I can think of. For that, I commend Safety 1st for carefully thinking that through. Now back to the real world stuff. Installation was super simple. This product comes as one unit, no assembly required. The adhesive strip is already affixed to the back of the lock. So all the installer has to do is peel the strip and press the latch to the door. Just remember to survey the spot on the door first because that adhesive is strong. Once applied, the latch works beautifully, preventing a child from going in or anyone from getting out. Just remember to be super attentive with this lock on. I use it to keep my LO out of the bedrooms where I’d lose sight of him, allowing him to still somewhat roam free while I can do some basic tasks around the house keeping him in my field of vision. This is in no way a tool to substitute for the watchful eye of a parent, by no means.

DO NOT READ ANY OTHER REVIEWS!! GET THE FACTS HERE!! Before I comment on the pros and cons of this device please understand that 90%+ of the 1-2 star reviews reference a MAJOR DESIGN FLAW of the device that is potentially very dangerous. This is not true and 100% user error! DO NOT let those comments prevent you from purchasing this product. Their basic gripe is that in the "unlocked" position a child can push the lever up into the lock position and lock the door. Meaning if you enter the pantry and your little one closes the door and pushes the handle up, you are now locked in the pantry with no way to get out. #1 - The device clearly states that you must push the lever ALL THE WAY DOWN when in the unlocked position. When the lever is all the way down, it clicks in place can only be moved by pressing the side buttons. HOWEVER, if do not push it all the way down until it locks, it will not lock and yes a child can push it up into handle locking position. I don't consider this a design flaw. This is complete user error. Now of course, you have to be the judge of weather you feel you can handle the responsibility of ensuring the lever is completely locked. #2 - There are users saying they had to kick their door down or kick holes in their door to escape once they were locked in (and posting pictures to prove it) This thing is strong. Don't get me wrong. It is stuck on there pretty good using the 3M tape. Certainly enough so that a toddler will not be able to pull it off the wall. However, I imagine it should be fairly easy to forcefully turn the handle in order to either break the device or snap it off the door. I mean I can't imagine giving this thing a downward kick with your heel and it not breaking from the door. The lesson is this, If you can kick a hole in your hollow-core door, you have enough force to use the handle to pop this thing off the wall. And if you are the one kicking down your door, you need to sit down and seriously re-evaluate your decision making abilities. So with that out of the way... Pros: This thing is so much better than other locks which require you to drill holes in your wall or door. And if they don't require that, they make it so that someone cannot enter from the other side of the door when the lock is in use. My wife and I use this on our front door. It is great because the outside handle of our door is a thumb push to open and the inside uses a lever push. This means that even when this child lock is in position (locked or unlocked) someone can still enter from the outside. PERFECTION! Also, it is incredibly ease to use and not frustrating. It is solidly built and doesn't rattle like some other devices we've tried. My 2 year old is a strong one who gets into all kind of mischief and after 4 months, he is yet to figure this thing out or make a dent. We have gatherings at out house regularly and every parent who has come over asks about the lock and is amazed at how well it works and looks on the door. A few bought some themselves. Cons: It only comes in one color. Our door was white so this was not a problem for us, but I imagine if you have a dark colored door you would want something like black or stainless looking. Ok, ok, I will be FAIR. As much as I dogged the parents complaining about a major design flaw. It would be a safety improvement to require the side buttons to be pressed at ALL positions when locking. This way there would be zero chance of being locked in. Again, this is not an issue for me, but I am sure the makers are kicking themselves for that one issue. Bottom Line: For $9 this is the best you can get. Works great. If you can remember to push the lever all the way down, you will have zero issues and you won't have to damage your door or wall. Buy it.

Our toddler likes to scape so this was an amazing solution to our problems. It’s easy to install and easy to press the 2 side buttons for an adult but difficult to figure it out for a kid 10/10

We have a 5 y/o boy with autism for whom bed time is a big struggle. No matter what we do we just can't get him to stay put once we put him to bed. Recently we moved into a house with this kind of door knob so the round childproof ones we used in our other house wouldn't work. This was the perfect solution! I applied it on the outside of my sons door and we lock it when we need to, only until he falls asleep. This kid is like the Hulk in terms of his strength and he has not been able to open it even when putting his full weight into it! HOORAY! He quickly gave up trying and fell asleep on the floor. Once he learns he can't get out we probably won't even need it anymore. My only complaint was that it was nearly impossible to peel the backing off to stick it on. I had to use a pin and tweezers to pry it off. This is a solid plastic lock that works exactly as advertised and doesn't look like a giant eyesore like some child proofing devices. I'm a huge fan! Highly recommend this product. Hope this helps! I did NOT receive this for free or at a discount.

First, a warning: If you have levers that are synchronized (as in, you turn the inside lever and the outside one turns as well) I really would not recommend getting this particular kind of lock. Other reviewers have mentioned that you can force the lock closed without using the buttons. Mine, when unlocked all the way, snap into place and don't move without pushing the buttons. If they're only partially unlocked you can easily just lift the piece that locks them. There is a very faint yellow mark that, when visible, indicates that the lock is fully open, but this may be a newer feature. That being said, if you have levers that function independently (you can turn either one and the other stays in place) then these are a parent's kid-proofing dream come true. I have 7 of these locks in use in my house right now (4 on bedrooms, 2 on bathrooms and one on the door to the basement). Thus far they have successfully foiled the mess-making schemes of my 3-year-old twins and my 4-year-old for about 3 months, which is longer than any other baby/toddler proofing item has managed. The twins generally figure out latches and locks in about a week and then they're useless. My older boys (6, 12 and 14) have no problems using the locks. The 4-year-old knows how to unlock them, but he's lacking both the finger strength needed to push both buttons at the same time and the coordination to do that while moving the locking part down, so it won't be long before he manages to use them (which is fine, we got them to keep the twins out of trouble). The decoy button is a brilliant feature, as well. I've caught the twins trying to use it to get doors to unlock on several occasions. They poke at it a few times, pull on the locking part, frown in frustration and then wander off to more interesting things. My only complaint would be that these do not also come in a darker color. Our levers are all oil rubbed bronze, and the doors are a darker wood, so the stark white of the locks stands out quite a bit and makes them very noticeable. I have not yet tried to remove one, and it will likely be a year or so before I do, but (if I remember) I'll post an update about the removal process.

This has been a really practical addition to our childproofing setup. We installed the Safety 1st OutSmart Door Lock on a couple of interior doors, and it’s been effective at keeping my toddler from getting into rooms they shouldn’t be in while still being easy enough for adults to use quickly. What I like most is the “hidden” locking mechanism. Unlike traditional baby locks that are obvious or require awkward sliding pieces on the outside, this one is tucked away so it’s not immediately visible or tempting for little hands. Once you get used to how it works, it’s very intuitive for adults. Installation was straightforward with basic tools, and it feels secure once mounted. It doesn’t feel flimsy or like it will pop off with repeated use, which is something I’ve had issues with in cheaper childproofing products. The only minor downside is that it can take a day or two to build the muscle memory for opening it smoothly, especially if you’re juggling bags, a toddler, or laundry. But once you adjust, it becomes second nature. Overall, a smart, low-profile childproofing solution that actually blends into the home better than most traditional safety locks while still doing its job well.

I really liked it, especially that I flipped it upside down and now I can open the door with the handle pulled up, no fear that the baby will open the door!
