Review: High quality lock that is easy to install - This is a good looking, very sturdy metal door-stopping lock that works well and is available at a good price. The video provided on the product listing was a helpful, step by step tutorial, and made it easy for me to set up, once I found my drill and the appropriate bits. One thing I will say is if you have a tight fitting door, you may need to chisel away some of the molding to get the lock into the narrow space between the door and the frame. I didn’t have to, thankfully, and the door closes easily with it on, but keep that in mind. The metal material is thick, and after locking it, I was unable to open the door, no matter how hard I tried, which is a nice sense of security to have. It also looks nicer than the ball-and-chain type locks you see in hotels, which I was considering getting until I decided on this one. I’m about to get another one for my garage door as well. Very satisfied!
Review: Use a longer drill bit if using the longer screws for strength - Our children had reached the age where they can open child-lock doors, and after discovering my 2 year old daughter has an exploratory vibe and had gone downstairs into the basement unnoticed, I decided to try one of these door locks. Note that this is interior to the house, so it's not so much to prevent break-in, just control access. Note that it's important to always have an egress path from where they are installed in a locked position in case of emergency. I would prefer a different design that has egress options on both sides of a door if you're trying to train a child to stay in their bedroom. I went with this model because the finish matched the rubbed oil bronze finish of the door hinges and door knob. After installation, the door security lock fits nicely with the decor. The door security kit comes with short screws that go into the door jamb that provide less strength, and longer 3" screws that should anchor to the stud frame around doors. There is more potential for stripping the screws if you only use the short ones that go into the door frame instead to the jamb. This is because the short screws would only anchor to the door frame that is often a type of decorative molding that doesn't have the structural strength of 2x4" studs (it doesn't take much force to deform the material). I decided that even if installed indoors, I wanted the door lock to be secure so I decided to use the longer 3" screws. The installation was easy but not without incident. Note in the picture with the drill bit and screw side by side that they are about the same length. When you put the drill bit in the drill, you have to sacrifice some length because the shaft sits in the drill chuck. The common drill bit length that you get in a normal drill bit set will not pre-drill the entire length of the longer 3” screw. So I pre-drilled as much as the shaft would allow me to drill, and used the lowest setting on the impact driver to push the screw into the hole. I had less than 1/2" remaining and it would not progress any further on the impact driver’s lower settings. I didn't have a longer drill bit length so what did I decide to do? I cranked the impact driver to 3 and after about half the distance I snapped the screw head clean off. Kraggle! Now I had a headless screw that was majorly stuck and the remaining screw was only protruding about 1/4" from the door frame. To remedy this, I used IRWIN Visegrip Quick Adjusting GrooveLock 10-in Electrical V-jaw Pliers to pinch the small remaining exposed screw length and spent about 15 minutes de-threading the screw from the door jamb. I needed the longer pliers length to get the torque to unscrew the threads, but when the pliers are that big, I still ended up deforming the door frame molding a little bit. I went to Lowe's and looked for a DEWALT 1/8-in 6-in Black and Gold Coated Hss Twist Drill Bit. Lowe’s was out of stock, but they had a 12 inch length drill bit in stock so I just decided to go with that. I would have preferred the smaller drill bit length but the door opening width still gives enough room with the 12 inch long drill bit to pre-drill the holes straight on. To ensure I didn't over drill the screw length, I placed a wrap of painters tape at the length on the drill bit to mark the screw length so I'd have no risk of over committing the hole and drilling through drywall just a few inches beyond the door jamb. Once I pre-drilled the correct length, I was able to use the impact driver on the lowest setting to drive the screws all the way into the door frame and jamb. Note with philips head screws, try to use the "fattest" impact driver bit that will still fit in the screw head. It's the best way to help prevent deforming the screw head from the bit slipping. In the end I had to borrow one 3" screw from a second kit that I had bought, though I could have gotten away with using two 3" screws on top and bottom and one small screw in the middle. Hopefully you read this making the same mistake! To open the door, you just have to pull out away from the door frame and then rotate to open. To close, you can simply rotate it back and it will snap into place, or you can pull out a little bit and you won't get the small "snap". All in all, I'm very happy with the end result, as now we have control of access to the basement to keep our little ones safe (and help keep the wife sane). It's easy to use and the wife loves it, so it's a win-win. Highly recommend if you want something to fit the house decor even though some people may consider it a little bit overkill.

### ⭐⭐⭐⭐⭐ Great Lock For Added Protection
*by B***N on July 29, 2020*

I live in a neighborhood where home invasions are frequent so i needed to think about what am i going to do to keep my family safe. I am a security conscious person. The first thing i think about is security in any situation i am in. This reinforced door lock is not only a simple device it's easy to install. I've seen a lot of people put this lock on the top part of their door and I can tell you putting it on top doesn't offer much security if an intruder tries to kick down your door. The middle of the door is the center of where force is met when someone kicks in your door. If you put this lock on top of your door the pressure from the blows to the door will put more pressure to the top area and snap the bottom portion of your door. The force of the blow is in the middle and that's where the lock should be to take the blows. How do i know? because I experimented on two doors using this lock. I placed one on top of my door were I see people putting it and i put one in the middle of the door. I found that the lock adsorbed the blows when the reinforced lock was put in the middle. We kicked the door down as hard as we could, we hit it with a sludge hammer, and also used a crow bar and it did not budge. When we put the lock on top we found that the door frame broke off and the door snapped because the pressure of the kicks and sludge hammer had snapped the door in half breaking the bottom part of the door. It all has to do with physics. This lock is well constructed and easy to open and close. I will say this. It's good to oil up the lock hinge from time to time to avoid friction which will occur over time. Also use concrete screws when drilling these onto the door frame. The screws that come with this are cheap and will break off if anyone dares to kick your door down. Overall this is an easy to install lock and well worth the money. I feel safe at night knowing nobody can break down my door even if they tried. This if placed right will withstand 500 and more lbs of pressure. SIDE NOTE: For extra added protection you should combine this with a metal door strike plate (as seen in photo). This makes it harder for people to break down your door and reinforces your door frame. Overall great solid buy and a must have to secure your home.
