Why You Should Consider a Door Chain Lock?

After going through the door chain lock reviews, we are pretty sure that you know door chains can keep your house safe to some extent. However, is that all that door locks have to offer? Not really!

Burglar Proof

The chain makes the door burglarproof. It will ensure that even if you keep the door open for some reason, no one can get inside that easily. You will also find a door chain lock with alarm options out there. Those will provide an additional layer of security to your door.


The door chains can even play an essential role in terms of child-proofing specific rooms of your house. Even if you install the chain on the front door, it will do a proper job of keeping your child inside the house when the door lock is unlocked.

Door Locks Usually Have a Long Lifespan

Most of the alternatives will not be capable of providing an extended overall service. In comparison, the best door chain locks will usually feature the construction of high-quality materials. Some of them are rust-proof as well. With those, you can expect to get security for an extended amount of time.

Blends Well with the Door

There are plenty of options available that will enhance the overall outlook of the door. They will make the interior side of the door look more welcoming while providing an additional layer of security. Now, that is something other locking alternatives for the door cannot provide.

How to Install a Chain Lock?

Even if you get an excellent chain lock formetal or wooden doors, it will not be of any use if you do not know how to install it. However, you will not have to worry because the installation process is not as hard as many make them seem to be. Do not believe us? Go through these steps:

Step 1: Gather the Needed Materials

Before you work with the lock or the door, you need to ensure that you have suitable materials. Check the packing to be sure of what screwdriver you would need.

No matter the type of door chain lock, no screws included with it will require a special screwdriver. And, in most cases, the lock would need a simple Philips head screwdriver. Also, check the size of the drills bits that you will require for installing the chain. Do get masking tape and a pencil for measurement purposes.

Step 2: Take the Measurements

Once you got everything required to install the chain, get into taking measurements. First, you need to tape up the template of the lock plate. The template of the lock would be the one that does not have the chain with it. You would want to position it about three to six inches above the deadbolt of the door.

However, you might not have a deadbolt lock with the door. In that case, place the lock template about three to six inches above the handle of the door.

Next, you should mark the points of the lock template using a pencil. Do you not know where to mark? Check the instructions that came with the lock. It should describe the points of the lock template that needs marking. After you are done marking the points, you can take the template down.

Step 3: Get into Drilling the Points

It would be time to handle the drilling machine. But where? The marks that you just made! Use a correct drill bit, or else you might have holes all over the door frame. For a clean finish, you should try to drill the holes in one go.

Step 4: Install the Lock Plate

At this point, the lock plate should be ready for installation. Place the lock template in place and tighten the screws in. If the screws that came with the lock feel a bit cheap, which would be for most of the lock, our recommendation would be to use a separate set of screws.

Step 5: Work on the Chain Mount

So, you have got the lock template in place, right? Now, it would be time to work with the chain mount. And for most cases, the chain mount would have a separate template. However, you should work with the position first. Place it just outside of the frame and ensure that it lines up correctly with the plate of the lock.

Step 6: Mark the Template of the Chain Mount

You would need to follow the same process as the template of the lock. Position it properly and mark the holes using your pencil. Then, use the drill again to predrill the holes of the chain mount. Again, follow the same process as before.

Step 7: Finishing Touches

Lastly, screw the chain mount using the correct screws. Ensure that you do not over-tighten the screws, or else they might strip. Test the lock. Make sure it can adequately secure the door, and no one from the outside can unchain the lock.

For most cases, the lock would make the door open just an inch. The broader the opening the lock leaves, the higher the chances of someone from the outside unchaining the lock. So, keep that factor in mind when you are testing things out.

Things to Consider Before Purchasing a Chain Lock for Doors

We know that our review section has made things a bit straightforward for you. However, things can get much more manageable! Let us walk you through the things that need to be in your mind before you make a purchase decision.


The first thing that you would want to consider is durability. And that would depend on the construction material of the lock. Usually, most manufactures will utilize regular quality brass or stainless steel. However, those locks would not have an excellent overall build quality.

Instead, what you want to look for is high-quality stainless steel or die-cast materials. Those will make the lock sturdy and allow it to handle a good amount of stress. And even if a burglar or intruder pushes on the door with heavy force, the lock will not break that easily.

Build Quality

Just the durability will not cut it when it comes to a chain lock. It needs to have an excellent overall build as well. When the quality is not up to the level, you will notice sharp corners. And that would make it hard to use the lock.

Furthermore, a good build also makes the lock look good, which will make it blend well with the door.


The front door is the first place where the eyes of your guest will be when you bid them goodbye. So, if you get a lock that looks out of place, the last impression will not be that good.

Considering that, get something that will blend well with the door. Opt for the lock with a modern style if the other ones do not blend that well.

Finish Options

More options in the case of finish is always a good thing. Also, there are some brands that will offer exquisite finish options. And those would make the door look unique by adding an aesthetic touch to them.

Setup Process

Another thing that you need to consider before making a purchase is the setup process. And it will highly depend on whether the lock comes with all of the required hardware or not. If it does not, you would need to go through the hassle of getting the hardware separately.

Secondly, ensure that the overall design is simple to work with when it comes to installation. If it requires special screwdrivers and tools, the setup process can be a bit difficult.


The chain is the thing that will hold the locking frames together and add a layer of security to the door. And the length of the chain matters a lot in this case. If it is too short, you will not be capable of viewing the outside. And if it is too long, there will be a high chance of the people from the outside being able to unchain the lock.

So, the chain needs to be the right length. And for this, consider the measurement and the type of your door.

Rust Proofing

Most of these locks will be made of metal. And metal has a tendency to react with moisture and oxidize, which causes rusting. However, some manufacturers will go one step ahead and coat the exterior with a rust-proof coating. We would recommend getting those as they will enhance the lifespan even further.
