Rated 4.8 out of 5 by 30 reviewers.
Rated 5.0 out of 5.0 by Can Prevent toddlers from exiting home to your Pool Yard This product is installed into the throat/frame of the door and when the latch is pulled across the door (& assuming it's installed at 5'-6" to the bottom of the latch--at least high enough so little ones can't reach), the device prevents the door from opening. This is especially good to prevent toddlers and others who cannot swim, from entering pool yards or even from just walking into the front yard and into traffic. It works much better than a slide lock or a chain b/c it's in the door frame and not the casing, so it more stable structurally as well. I've only found it at Home Depot and through Locksmiths February 10, 2013
Rated 5.0 out of 5.0 by Stealthy Security I love these locks. We are moving into a new home and I decided I wanted to up the ante with security in our new home. To make matters worse, our back door has a large glass pane and our front door has a thin window that runs the length of the door in the wall on the locking side. I figure it would be relatively easy to smash the front window and reach in and unlock the deadbolt. (If you've ever wondered how easy it is to kick in a standard door, google it. You will run out to the hardware store before the first video you watch is over. Standard locks and screws just don't cut it. No really, google it.) Pros include: A.) they are very sturdy B.) according to reading I've done, they can withstand up to 800 lbs of force C.) rubber bumper to protect door D.) THEY ARE NOT VISIBLE FROM THE OUTSIDE That last one is huge. If someone came up and broke the glass by the front door, they wouldn't have any way of knowing that I have one of these further up the door and one opposing the bottom hinge. That means they could turn the knob and the deadbolt and still have a whale of a time kicking my door but it still wouldn't open ----and they wouldn't be able to see why!---- That. Is. Awesome. There is simply no way to open these from the outside. It's as simple as that. It makes me feel much safer knowing we can barricade ourselves in. Many, many people talk about these as a method of child-proofing (which is indeed true) but the security aspect really needs to be emphasized here as well, if not more. I have at least one of these on every door that connects to the outside (including between the house and garage). In general the mounting plate is thin enough that out of 4 installed, I only had to mortise one (cut a little notch in the wood to fit the plate to keep it from bumping the door too much). The mounting portion is perhaps 2 credit cards thick of hardened steel. It is thin enough to be versatile yet clearly beefy enough to put up a good fight. A few suggestions when it comes to door security all around: A.) Replace the stock screws in your door hinges (to both the wall and to the door) & mounting / locking plates with longer screws. If you've never looked before, you will be utterly shocked and dismayed by the tiny 1" screws in your wall. They barely pierce the trim around your door. They do not pierce the 2x4's that actually hold the door up. In stead of the stock screws, get a minimum of #8 (pref #10/12) 2.5-3" screws (pref 3"). These will be longer and pierce through the trimming around your door into the actual 2x4's that make up the actual structural integrity of the door. To back up my point, these locks come with 3" screws. You will likely need to pre-drill holes to help lead the screws since they are so much more substantial. B.) For security reasons, DO NOT MOUNT THESE RIGHT NEXT TO YOUR DEADBOLT. From both a security and STRUCTURAL point of view, it makes sense to spread it some distance (a ruler's length at least) from the deadbolt/handle of the door. That is why your hinges are spaced out the way they are. The spread the load out and also evenly distribute force to the door frame. As a result, if you really are hankering for security, consider mounting them opposing your hinges. Besides, if someone ever tried to reach in and undo your deadbolt/handle, they couldn't then feel this lock unless you put it right there for them. It just doesn't make any sense to do it that way. In terms of installation, you should see if these will fit in the gap of your door prior to installing. It's as simple as trying to slide the thin bit in-between the door and the frame. You may find you don't need a mortise at all and you may also find that it may fit a little more smoothly just a few inches up or down from where you first tried it no fuss. You may also find that it just plain wont fit if your door is fitted really tightly. That means it would require a mortise (cutting a bit of wood away in the frame to accommodate a space for it.) That may suit your ability, it may not. When installing, you use the central screw first since it allows some measure of adjustment. Mount that screw first, close the door and see if it needs to slide in or out or be angled just a hair. Once you see how it needs to sit in relation to your door and frame, you can then open the door and install the longer screws. The first screw will serve to hold the plate up while you then drive in the longer structural screws. Very easy and intuitive. All in all, I'm very pleased. The singular issue I can foresee with these locks is that when you have them on all your doors, if the door you choose as your access point is inaccessible for any reason (think, you always enter in through the garage but the garage door motor broke and you're stuck outside) then you cant get in your other doors. An exceptional issue I'm sure. Would definitely buy again and will surely install these wherever we live now. June 1, 2015
Rated 5.0 out of 5.0 by Good Door Kick In/Break In Prevention Alternative Item is well made and appeals to the eye. It appears that it will deter or limit success in attempts at kicking in doors. Hopefully we won't have to put it to the test. Does afford a sense of security and peace of mind in the evening. I have them installed on all exterior doors and garage inner door. February 20, 2013
Rated 5.0 out of 5.0 by great value So easy to install & utilize. Very well made and extremely sturdy. Would strongly recommend as an additional lock to all your doors leading outside. January 27, 2015
Rated 5.0 out of 5.0 by simple security easy to install, simple to operate. coupled with a good solid door, nobody is getting in. January 27, 2015
Rated 4.0 out of 5.0 by Quality Product Very solid good quality, easy to follow instructions December 30, 2014
Rated 4.0 out of 5.0 by works well, easy to install, high quality Check out youtube for the installation video. The instructions that came with the product isn't the best. It's also known as the door guardian. There are 2 versions of this product out there, a 4 screw installation and a 3 screw. It's easier to use a impact driver to drive in the 4 inch screws.

Rated 5.0 out of 5.0 by secured door Great way to secure doors from the inside of your home with no lock or key. Ideal for bedroom doors, basement doors or house door to garage. Plus if you're renting, you can remove the long screws provided and take it with you to your next home. A simple supplement to add to your home's security arsenal. This is also great for keeping the very young, and the elderly from opening the doors from the inside. It requires finger strength and dexterity, so it's good for that purpose. October 7, 2014
