Prime-Line U 11441 Door Reinforcement Lock – Add Extra, High Security to your Home and Prevent Unauthorized Entry – 3” Stop, Aluminum Construction, Red Bronze (Single Pack)

I recommend this lock to everyone. There are many ways to make your home more secure without spending much money and this is one of my favorite. It's extremely well made and even looks kind of elegant. It is quite easy to use, but honestly it could be easier. I wish they had added a grip or loop of some kind to make it easier to unlock. My concern is that someone unfamiliar with it would be trapped inside during a fire. Occasionally it will get bumped out of position when it's unlocked, so when we try to shut the door, the lock is in the way and the door bounces off of it which is startling (and could feasibly damage the door).For installation, you do need self-drilling screws and a powerful driver of some kind, which could be expensive if you don't have the driver already, or you can use a less powerful drill with a very long drill bit, and those bits can be expensive and hard to find. This type of hardware kit should always come with a drill bit.If you have a door that doesn't fit well in the frame, you may have trouble placing this lock. The bottom half of our door has a huge gap, and this lock doesn't have a ton of overlap even on doors that are hung correctly. There are a lot of YouTube videos showing how to fix the gap in a door. Usually you just need to bend or shim the hinge.Most burglaries happen due to people leaving windows and doors unlocked. The burglar just walks right in. Beyond that, they kick in doors, or use the items in your yard (ladder, trellis, large rock, hide-a-key, etc.) to break into your house. Most front doors on most houses and apartments are installed with very short screws that only go into the door trim, not the heavy frame. If your door is kicked in, it's not usually the door or the lock that fails; the strikeplate just gets blown right out of the door trim. So almost anyone can kick your front door in--it doesn't take a lot of strength or skill. If you replace the screws in your strike plate and hinges with 3-inch or longer screws, the door will be attached to the studs in the wall and will be vastly more difficult to kick in. It will take so long and be so loud that the burglar will likely move on, not wanting to attract any attention. This kind of lock adds another layer to that, and gives you more time to react. Even if someone bumps your locks, they won't be able to open the door. This also keeps out uninvited landlords and maintenance workers. :)Summary of some simple/affordable security actions and ideas:* if someone wants in, they'll probably get in; the goal with security tools is to slow them down and get your attention, so you have enough warning to call for help and hide or prepare to defend yourself, or more ideally, to make breaking in so time-consuming and noisy that a potential burglar has to give up and move on* burglars may use anything around your home to break or climb in, so try to minimize the tools you give them* replace door screws with 3"+ screws* replace strikeplate with security strikeplate* add door reinforcers (metal plates that protect doorknob and deadbolt from kick-ins)* put battery-powered alarms on your windows and doors (you can even get alarms that detect your window being broken)* add screw-on locks or put a charlie bar/1" doweling in your sliding door and window tracks* if your sliding windows and sliding doors can be lifted up and out while they're closed, drive a screw into the upper track to prevent it (google this if you aren't sure)* don't leave boxes for things like giant flatscreen TVs in your curbside recycling, and don't leave your address on similar attention-getting packaging that you're dropping off at a recycling center* don't keep desirable-to-burglars possessions where they're visible to passersby* have some means of protecting yourself in case someone does get in (gel pepper spray is a good place to start looking)I don't believe in being paranoid or lowering your quality of life for "security," especially since the risk of a home invasion is so relatively low. However, we moved into a place that had already had both doors kicked in and I needed to take action to avoid anxiety about it, without going overboard or spending a ton of money. I think these tips are a good compromise, especially since they require so little money. Since I know anyone breaking in will have to make a lot of noise (and if they get in, I'll be waiting), I feel less anxious. I used to worry that someone could already be in the house and I wouldn't even know it. Now I have a bunch of passive systems in place, and a big dog :), so I feel a lot better.

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.

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!
