High Security: Commando Lock Total Guard

Commando Lock Total Guard

Finally, we have the Commando’s Total Guard, another shrouded padlock that both the LockPickingLawyer and BosnianBill have praised over the years. With large amounts of hardened steel covering its shackle and a laminated steel body, this lock will not be easy to break.

It also looks very cool (with its black and steel body). 

One of this lock’s most interesting features is that you need to turn the core twice to open the lock and remove its shroud. While this makes it a little harder to use, it will be a real pain for anyone trying to pick open the lock.

This is because if they manage to pick the lock open, they will find that the shackle is still attached and the shroud is still not removable. Therefore, they would need to pick the lock a second time to remove the shackle and shroud from what it is securing.

A random selection of security pins in the 5-pin cylinder means it can have up to 10 security pins, making this lock challenging to crack.

Best Combination Padlocks

Combination locks aren’t suitable options for high-security applications. However, they are fine on a gym locker or similar low-security applications but shouldn’t be used to secure your shed. 

All combination locks have a fatal flaw that is almost impossible to get around. However, if someone has enough patience, they will get into the lock by trying all the possible codes

Three hours is the maximum time it takes to try all 4-wheel combination padlock’s possible codes (10 000) and will most likely be around half of this time or less, depending on your code and where the thief starts. 

A 5-wheel combination lock has 100 000 possible codes, increasing the difficulty to around 30 hours to try them all.

Best Combination Padlock: ABUS 190CS/60

ABUS 190CS/60 combination padlock

This one is a beast, and that’s precisely why it’s on this list. It is likely that a thief will merely see this lock and give up because it looks like it’s going to put up a fight. 

It has a huge hardened steel body with an alloy shackle that will prevent people from cutting it. 

BosnianBill tested this lock, and he had trouble finding any weaknesses.

So physically speaking, this lock will not break, but as we mentioned above, if someone wants to sit there and try all the possible codes, they will get into this lock in under 3 hours. For this reason, we would not recommend using this lock in a remote place where a thief will have enough time to gain access.

How We Choose Padlocks

Padlock on a fence

Most websites choose their best padlocks by finding the ones with the most sales, features, and reviews. However, we select padlocks very differently.

Our Methodology

We choose our padlocks based on the experience and feedback from the lockpicking community as well as tests, the experience of customers, and security certifications from lock security certification organizations around the world.

All this information allows us to find locks that guarantee high security with minimal weaknesses and for the best price

Lockpick Ratings from r/LockPicking

This lockpicking subReddit has a ranking system for locks that we also use to make decisions because this group of people is among the best lock pickers in the world. So we trust them to know what locks are best and what ones have some terrible flaws.

history of locks

Lockpicking Community Experts

We also include input from lockpicking community experts like LockPickingLawyer and BosnianBill

We are highly regarded in the community and quite enjoy letting everyone know when a lock doesn’t do what it claims to do or has fatal flaws that make it useless.

PRO TIP: You can also look at the locks that LockPickingLawyer recommends.

So, without further ado, let’s look at our best padlocks for security!

Padlock Features

Padlocks come with many different features and are made from a wide variety of different materials. These different combinations of materials and features will determine which option will give you the best lock for your situation. 

This is why knowing what to look for is essential. 

To find the best padlock for you, you want to get an affordable one with all of the following features:

  • Pick resistance: Pick resistance is how well a lock can resist a lockpicker trying to gain access to the lock. This is shown by the belt rating the lock has been rated by r/lockpicking
  • Bypass resistance: Bypassing a lock is where you can use a defect in the lock to open it without needing to open it at all. It can be done by pushing something inside the lock, hitting it with a hammer, or using a magnet to move something inside the lock, opening the lock. Unfortunately, this is a significant risk, and many locks on the market have bypass-resistance issues.
  • Resistance to brute force and cutting: If a lock can be cut open with a hacksaw, grinder, or even hammered open, it is not resistant to brute force. We found locks with superior brute force and cutting resistance and included them on our list of best high-security padlocks.

Let’s discuss padlock features in detail.

Cutting a padlock with bolt cutters

Padlock Core

A  padlock’s core is where the key goes and is the part that determines the lock’s resistance to picking. It also impacts the lock’s overall resilience. There are many different types of lock cores and they all contain different pins and tolerances. 

No two locks are exactly the same, and this is by design. But there are still consistent differences between many locks.

The Shackle

A padlock’s shackle is the main moving part on the top of the body. This is what you would use to attach it to something you want to secure. 

They come in different varieties, thicknesses, and materials. Usually, the thicker the shackle, the more secure the lock.

Padlock shackle construction comparison

Padlock Shackle Material

The shackle’s material is very important. It can range from hardened steel to stainless steel to more exotic varieties that are difficult to cut like, boron steel.

Shrouded vs. Unshrouded

A padlock’s shroud is a large amount of steel that surrounds and protects the shackle. It can either be attached or detached from the padlock’s body.

A shrouded padlock is much harder to cut, as the shackle is completely covered in a separate piece of metal that would also need to be cut through.

Padlock Body

Padlock bodies come in many shapes and sizes, from large solid alloy steel bodies to small laminated versions to rounded ones. Their materials have a significant effect on their security level, durability, and strength.

padlock body material

Breaking Strength

This is the most important padlock body feature. You want the padlock body to be as strong and durable as possible. 

For the highest strength, stainless steel and hardened boron steel are the best. 

Aluminum and aluminum alloys are used for locks that are meant to be lightweight.

Look for brass and stainless steel padlock bodies if you need your padlock to be weather resistant.

Drill Resistance

Finally, drill resistance is a feature many high-security padlocks have, as it’s not usually necessary for low-security locks. 

Drill resistance can be obtained in a number of ways: 

  • Anti-drill inserts are pieces of hard metal placed in the lock (in areas where someone would typically try to drill into the lock) to stop or redirect a drill bit.
  • The correct padlock body material plays an essential role in preventing drilling. Some materials are harder to drill than others.
  • The padlock’s body shape is also used to control how easily a padlock can be drilled into. Simply put, angles and round parts are much harder to drill into than flat faces.

So, keep an eye out for materials that are hard to drill, contain anti-drill elements, and have a complicated shape with curves and angles.

history of locks

Bottom Line

Finding the best padlock can be challenging because there are so many options out there. If you are reading this article, you must be interested in finding something that will give you a high level of security. Luckily for you, we have already found the best padlocks.
