Door Guardian Reinforced Security Lock for Household Doors

Bought two of these to keep my 3 yr old from opening the doors. They came without the clam shell which I'm glad of. Quality of these are heavy duty, very sturdy. Lock mechanism snaps close smoothly and easily. Installation is a matter of screwing in three screws. Package comes with two 3" screws and three 1" screws. The 3" screws are for wooden doors, and you use one of the 1" ones as a place holder. If you have steel doors, then you'd use all three 1" screws; there's special threading on them.Installation tip:If you don't have an impact driver, then pre-drill the holes for the 3" screws.

If you want safety and you want it done right the first time then buy this. I had spent money on safety features to keep our front door, back and garage doors from getting opened by our little one. Well I stumbled across this and figured I would give it a try since little man figured out all the other safety ones out there. My husband placed it on the doors with his drill at closer to the top and it worked. It has worked so well when we moved I bought more for this house. It is like a magnet but you have to swing it out and around so harder for little ones to figure out. I bought when my son was 2 and he is now eight. He can close it now but would have to stand on a chair and have me show him how to open it. I have to show all guest one time so they know. It is the best safety door closer I have ever used. Family and friends order them once they see it. They also have different colors last house I needed gold this house is white.

We purchased two to put on back and front door to make sure that our toddler doesn't accidently let herself out. They are very sturdy. We have inadvertently tried to open the door while the deadbolt was down and we could not open it and it didn't break. While the end product is very good, the installation was a little frustrating. The provided self-tapping screw was difficult to install. So hubby drilled his own pilot hole instead of letting it "self tap." Once he abandoned the self-tapping screw and opted for his power tools, it took him about 10 minutes to install each.

Based upon the recommendations here, I bought this deadbolt for a new exterior door I installed. In less than three weeks the mechanism that allows it to open and close was broken - the lock was used only at night. Either it was defective, or maybe all those five star ratings came from the seller.

okay so I was mixed on getting these or not because of other reviewers saying that they had to chisel the door away. Well I took a chance and it fit perfectly! I order 4 more for the other doors. my moulding does pop out a good 1/2 an inch and no sweat. The problem has nothing to do with moulding but how close your door closes up to the fixed side moulding. If you have a gap install is super quick. If the gap is tight when on the inside moulding where the plate will be installed you will have to use a chisel and hammer and shave a bit out. This is easy and is covered with the installed plate so dont sweat it. Nice looking and really just blend into the door moulding. Very easy to use. Cons are the crap screws they give you so just throw those out and install with a couple of good 2" wood screws. With the "good" screws the install takes 30 seconds! Very secure and quality built.

Anybody with a special needs child knows how hard it is to keep them from escaping or getting into things they shouldn't be! This Door Guardian Lock is an easy but effective way to keep them secure! Or an extra way to keep thieves out!! Simple to install and very easy to use as well. Once locked, it makes your house a fortress! We use one on the front door and one on the back. They come in different colors to match any trim, and they even make a lock for sliding doors too!

I mean, it works really well, but I use it to keep my kids from running out of the house. I should have just installed a deadbolt up high, because my husband can't get in the house even with a key when this is latched, which is the majority of the time.

My wife and I are caring for her 99 year old mother who has severe dementia. She constantly walks out of the house and wanders off. I tried the Addalock on all doors, but she soon figured out how to slip the locks and escaped several times. I found her once two blocks from our house wandering around trying to find her parents who passed away 50 years ago.I put one of these on each of four exit doors. Installation is quick and easy. On all but one door, I was able to install the lock high enough on the door that she can't reach it. She's only 4'5" tall.It's been a week now, and she is unable to figure out how to slip the lock and open the door. We can all sleep through the night around here now without fearing another "Great Escape"!
