How to Install Chain Lock on Metal Door

A chain lock is a security device used to secure doors, windows, or other openings. It consists of a chain attached to a door or window frame and a lock mounted on the door or window. Many people use chain locks in conjunction with other security devices such as deadbolts and padlocks. Therefore, it is crucial to choose a chain lock made of high-quality materials and designed for the specific type of door or window that you are securing.

This is the most basic type of chain lock, and it usually has a simple design. It is typically made from steel or brass, and it has a small chain that attaches to the door handle.

2. Heavy Duty Chain Lock:

As the name suggests, this type of lock is much heavier and more durable than a standard chain lock. It is typically made from stainless steel, and it has a thicker chain that is designed to withstand more force.

3. Keyed Chain Lock:

This type of chain lock has a keyed cylinder used to lock and unlock the chain. This is a more secure option, but it can be more challenging.

4. Combination Chain Lock:

This type of lock allows you to set your combination, making it much more difficult for someone to guess. This is an excellent option if you want extra security, but it can be tricky to remember the combination.

A Stepwise Guide on How to Install Chain Lock on Metal Door

Step 1: Determine What Type of Door You Have

There are two types of metal doors- the flush type and the recessed type. The former has a door surface that is even with the frame, while the latter has a door surface that is set back or recessed into the frame. For this project, we will be focusing on how to install a chain lock on a metal door that is flush with the frame.

Step 2: Choosing the Right Size and Type of Chain Lock

Now that you know what type of door you have, it’s time to select the right size and type of chain lock. To do this, measure the width of your door and add 1-2 inches to allow for movement. Next, decide what type of chain lock you would like. There are two main types- a surface mounted chain lock and a mortise chain lock. Surface-mounted locks are easy to install but not as secure as mortised ones. On the other hand, mortise locks are more challenging to install but provide more security.

For this project, we will be using a surface-mounted chain lock.

Step 3: Preparing the Door for Installation

Before installing the chain lock, you need to prepare the door. First, use a marker or pen to mark the location of the holes for the lock. It’s essential to ensure that these holes are level, so we recommend using a level. Once the holes are marked, use a drill to create pilot holes. Be sure to use the correct size drill bit for your screws.

If you use a jigsaw, you will also need to cut out a rectangular hole for the chain lock. This hole should be big enough so that the chain can move freely when the door is open.

Step 4: Installing the Chain Lock

Now it’s time to install the chain lock. First, insert the screws into the pilot holes and hand-tighten them. Next, insert the chain lock into the rectangular hole and secure it with the screws. Be sure not to overtighten the screws, as this could damage the door.

Step 5: Testing the Lock

Once the lock is installed, it’s time to test it out. First, close the door and engage the lock. Then, try to open the door from the outside. The door should not open. If it does, check to ensure that the screws are tight and that the chain is securely engaged.

Installing a chain lock is a quick and easy way to add an extra layer of security to your home. With just a few tools and some basic knowledge, you can have a new lock installed!

Tips and Tricks:

  • When installing a chain lock on a metal door, it is essential to make sure that the chain is positioned correctly. The chain should be positioned so that it is not loose and does not rub against the door.
  • It is also essential to ensure that the screws are correctly tightened. If the screws are not tightened properly, the chain could come loose and cause the door to open.
  • If you have a deadbolt lock, it is essential to make sure that the chain is positioned so that it does not interfere with the operation of the deadbolt.
  • It is also essential to ensure that the chain is not too long. If the chain is too long, it could get caught on the door and cause the door to open.
  • If you are not sure how to install a chain lock on a metal door, it is best to consult with a professional. A professional will be able to help you position the chain correctly and make sure that the screws are perfectly tightened.

Where Should a Door Chain Be Placed?

A door chain is a security measure that can increase the safety of a home or business. The chain is installed on the doorframe and allows the door to be opened for a limited amount, allowing the person inside to verify the person’s identity outside before opening the door fully.

Testing the Lock

While door chains are available in various sizes and styles, they should always be placed at a height that is within reach of the person inside. In addition, the chain should be positioned so that it cannot be reached through an open window or door. By following these simple guidelines, homeowners and businesses can help to ensure that their property is as secure as possible.

Why Won’t My Drill Bit Go Through Metal?

If you’re having trouble drilling through metal, it’s likely because your drill bit isn’t made for that purpose. Metal is a lot harder than wood, so you’ll need a different type of drill bit to get the job done. Various drill bits can be used on metal, including titanium-coated, carbide-tipped, and cobalt drill bits. With the correct type of drill bit, you should be able to drill through metal quickly.

Titanium-coated drill bits are one of the most popular drill bits for metal. They’re designed to stay sharp longer than other drill bits to handle repeated use. Titanium-coated drill bits are also less likely to overheat, so you can use them for extended periods without worrying about them getting too hot.

Carbide-tipped drill bits are another excellent option for drilling through metal. They’re made with a more complex material than titanium-coated drill bits so that they can withstand even more wear and tear. Carbide-tipped drill bits are also less likely to break or chip, making them a good choice for use on more rigid metals.

Cobalt drill bits are one of the best choices for drilling through metal. They’re made with a cobalt alloy that makes them highly durable. Cobalt drill bits can handle high temperatures and stay sharp longer than other drill bits. If you’re going to be doing a lot of drilling, cobalt drill bits are an excellent option.

How Do You Know if a Drill Bit Is for Metal?

There are different types of drill bits for other materials. If you’re not sure which kind of bit to use, there are a few ways to tell. First, check the packaging. Most drill bits will be labeled with the type of material they’re meant for. However, if you can’t find this information, there are a few other ways to tell.

Installing the Chain Lock

Metal drill bits typically have a shorter and more blunt tip than those meant for wood or plastic. They also tend to be more complex materials, such as carbide or titanium. In addition, metal drill bits typically have a smaller diameter and thicker walls than those intended for other materials. By keeping these things in mind, you can ensure that you choose the right type of drill bit for your project.


While a chain lock is not as strong as a deadbolt, it can still provide some security for your home. By following the steps we outlined in this article on how to install chain lock on metal door, you can install a chain lock on your metal door in no time. However, remember always to use caution when using any lock and keep your home safe and secure.
