Securing your home or business with high quality security padlocks is an important part of a total security system. Never rely on easy to break locks.

When comparing high security padlocks, you need to consider how you are going to use your padlock. 

Make sure that you have enough space for the lock itself and that you will be able to easily reach it. 

Larger locks, while they may offer additional security, can be difficult to unlock in tight spaces.

Make sure that you take into consideration not only the size of the shackle, but also its construction material. 

The shackle length will play a huge role in where you can use your lock, and there are many sizes for you to choose from. 

It’s also important that you consider the shape of the lock that you’re going to buy, as different shapes have different features and benefits. 

Disc padlocks are round and are a great option for securing doors or for use with chains or security cables. 

Shutter locks are great for securing external security roller shutters, but they can also be used on security chains or parking posts.

Probably the most common and well-recognized padlock shape is the conventional style padlock. 

These can be used for applications like locking your toolbox to securing a factory gate. 

They come in many different sizes, with different size shackles, and are available in a number of different materials as well.

High Security Padlock Advantages

A high security padlock is a great way to help protect items that you don’t want to have stolen. 

Thieves are opportunists. If they discover you are utilizing cheap locks, they will break in.

While some people think that they don’t need to worry about the quality of lock that they buy, I believe that you want to spend a little bit more sometimes to make sure that you get the best one for your needs.

Remember that high security padlocks are going to have additional safety features, such as anti-pick pins and larger shoulder shrouds. 

Together these features are designed to help you keep your belongings safe from theft.

What to Look for in a High Security Lock

There are a few important things for you to consider when you go shopping for a new security padlock. 

First you will want to consider is the material that the lock is made of. 

This will have a huge impact on how durable and strong your new padlock is. 

Alloy steel and carbide are your best options, as they are much less likely to be damaged by someone trying to break your lock.

You also need to take into consideration the number of pins that the key has. 

A key that has more pins is going to be much more secure than a key that has a fewer number of pins. 

While this isn’t the most important factor to consider, it is one that I think you need to be aware of.

Additionally, look for an anti-drill plate. 

These hardened plates do a wonderful job at helping prevent a drill bit from being able to break through the lock. 

While they are not always available on all padlocks, they are a good feature and one that I think you need to consider.

In this YouTube video from Bosnianbill, you can easily see as they compare different security locks.


It’s very important to choose a padlock that is not only the right size for your intended use, but can be used for your application. 

I know of some people who have bought padlocks, only to find out that they are not designed for outdoor use or that by using their new padlock near salt water it was ruined. 

Look for a padlock that was created for use in your specific area.

You also need to make sure that you have an extra key on hand so that if you lose your padlock key that you will be able to open it. 

Unfortunately, all of the safety features that work so well to protect your belongings from theft can also make it very difficult for you to cut through and open your lock if you lose your key.

Finally, one more problem that you can encounter is choosing a lock that isn’t strong enough for the job. 

I think that if you have the money and the space, it is always best to opt for a high quality security padlock.
