Types of Door Locks Ranked by Level of Security

If you have experienced a break-in, you know how it feels to have your personal space violated. Nobody wants to arrive home and find that their house has been broken into and precious items stolen. Worse yet, for your house to be invaded while you or your children are there.

It’s vitally important to make sure that your entrance doors are secure.

There are many types of door locks for sale and adding a robust lock to your front door doesn’t mean that you have to sacrifice style or aesthetic appeal for high security. In fact, there are so many different types of locks on offer that the choice can become a bit overwhelming!

In this article, we will look at different types of door locks and rank them according to the level of security they offer.

Choosing the Right Lock for Your Home

When deciding what type of lock to purchase you need to assess a few things first.

What are your security priorities, do you want the lock to have aesthetic appeal, or doesn’t this matter, are you looking for convenience, what type of door are you securing, and how much are you willing to spend on a lock?

If you aren’t intimidated by technology, a smart lock might be the way to go. If you prefer something more traditional, a key lock could be the right choice for you.

Smart keyless door locks offer the convenience of easily opening your door even when your arms are full of groceries. They are also handy if your house needs to be accessed by dog walkers, babysitters, repairmen, or cleaners. With a smart lock, you can let people in using your phone or give them access with a temporary passcode. You don’t have to distribute keys to people and then wonder where those keys have got to and if your house is still secure.

The more traditional key lock offers a lot more possibilities in terms of upgrading the strength of your door materials as well as the lock itself. The number of designs and finishes that key locks come in allows for much more personalization and you can buy a lock that suits the style of your home.

Both smart and traditional door locks come with security limitations. You can’t always upgrade a smart lock’s components, and they could possibly be hacked into. A deadbolt is only as strong as the doorframe it’s attached to. When last did you assess the strength of your doorframe around the deadbolt? And are you one who keeps a door key hidden in a pot plant?

Deadbolts offer the most security when it comes to key locks. They are usually used on exterior doors. You can get single or double-cylinder deadbolts with strength ratings of ANSI Grade 1, 2, or 3 – Grade 1 being the best.

Doorknob twist locks, which are opened with a key, are not particularly secure on their own. They can be used together with a deadbolt to bolster the security of the door.

In the end, all door locks have their flaws and are subject to human error. However, that doesn’t mean that all locks are equal. There are certainly ones that perform better than others.

Door Lock Types

Here is a quick summary of different types of locks and what they offer.


Padlocks - Types of door locks

These are the only lock types that aren’t permanent. They are meant to be portable and come in a wide variety of shapes and sizes.

There are two types of padlocks:

• Keyed – as the name implies, a key is used to operate these padlocks

• Combination – number dials open the lock when the right combination is entered.

Usually used on exterior doors a single deadbolt uses a key cylinder on the exterior side of the door and a thumb turn on the interior side to open and close the door lock. A double-cylinder deadlock uses a key cylinder on both the interior and exterior of the door. While a double deadbolt has a clear advantage in terms of security, it can pose a problem in an emergency when exiting quickly from your home is imperative.

A hybrid between the single and double deadbolt is the lockable thumb turn. While operating in a similar matter to a single deadbolt the thumb turn can be locked with a key.

Knob Locks

Frequently Asked Questions

Are padlocks safe?

Most padlocks are mass-produced. This means that the same key that opens your padlock opens other padlocks of the same model. If you have a combination padlock, someone could have chosen the same combination as you. If you purchase a Grade 4 padlock you are buying a lock with an extremely strong resistance to cutting and pulling as well as 5000 key differs (this refers to the number of possible keys for any given lock. Five thousand key differs means that there are 5000 different keys/combinations and only one that can open that particular padlock.) So yes, padlocks are as safe as the model of the padlock you buy but they may not be the best form of security for a front door.

Are deadbolts safe?

A single-cylinder deadbolt has an obvious security weakness. The thumb turn on the inside of the door can be turned without a key. So, if an intruder somehow gets access to the interior side of the door, they can simply let themselves in by turning the thumb turn. A double-cylinder deadbolt does away with this flaw by having key access on both sides.

Why are lock security ratings important?

ANSI grades help you to know how much protection a lock gives you.

Concluding Thoughts

With such a range of locks available you are spoilt for choice. Each lock has its pros and cons. Consider your lifestyle and security needs before making a final decision. Any lock you choose will add an extra bit of security to your home.

Traditional door locks can be reinforced. Smart locks cannot. And any lock is only as strong as the door they are attached to. Make sure your door is made of strong materials with a solid core to ensure added security.
