Master Lock ‎647D Combination Padlock:

Best Budget-Friendly Option:


  • Material: ‎Metal, Steel
  • Dimensions: ‎0.56 x 1.2 x 2.86 inches
  • Weight: ‎2.82 ounces

Unique Features:

  • Cut resistant
  • No keys required


  • Good for indoor use
  • Great value for money
  • Classic combination padlock, easy to use


  • Hard to reset the lock code
  • Prone to damage from water

The Master Lock 647D is a classic combination padlock that will bring you great value for its price. It’s the cheapest and not the sturdiest lock on our list. But it will get the job done for sure.

Master Lock’s Combination Padlock is your classic yet reliable and convenient lock. This padlock offers both convenience and security thanks to its keyless operation and customizable three-digit combination.

First, let’s talk about its construction. Its solid metal body ensures durability and sturdiness. But in terms of sturdiness, it does not compare to the other locks on this list. Also, the Master Lock Magnum is better in terms of weather protection.

Apart from the sturdy body, the steel shackle is thick. But compared to the other locks, it’s not thick enough to be cut-resistant. Despite its shortcomings, this lock is still suitable for basic protection.

Its black finish adds a sleek and stylish touch to it. This makes the lock kind of posh looking. If you think classic combination padlocks are ugly and don’t go with you, this will change your mind. 

What we like most about it is, its price, compact size and that it is keyless. You can easily set your own three-digit combination however you want. We love it when a lock just eliminates the hassle of carrying around keys.  

Brinks Commercial Stainless Steel Keyed Discus Padlock:

Best Lock Against Cutting Threats:


  • Material: Stainless steel, rubber
  • Dimension: 1 x 2.88 x 2.81 inches
  • Weight: 1.21 pounds

Unique Features:

  • Pick and pry resistance.
  • Minimal shackle exposure
  • Full-radius rubber bumper


  • Solid construction.
  • Four-pin brass tumbler cylinder
  • Impressive cut strength of up to 8100 lbs.


  • Not weatherproof
  • Sometimes the lock may get jammed

If you do not mind using a key and spending a bit more money on your lock, this Brinks Discus padlock could be just the thing for you. Although it’s small and compact, it will surprise you with its durability. 

When we first came across this lock, it seemed a bit weird because of its round shape. But this padlock packs a punch with its impressive features and solid construction. That’s what makes it a dependable choice for safeguarding your belongings in the Ubox.

First, let’s talk about security. The Brink’s padlock is equipped with a four-pin brass tumbler cylinder, providing excellent pick and pry resistance. The round-shielded design of the padlock further enhances security by minimizing shackle exposure, making it harder for thieves to cut it. 

Other than the ABUS Granit, this is the most secure lock on our list in terms of cut resistance. But if you want weather protection, the Master Lock Magnum is better that the Brinks Discus.

But this lock is way sturdier than Master Lock 647D. Strength is the area where Brink’s padlock excels. Its steel shackle boasts an impressive cut strength of up to 8100 lbs, which is the highest among the locks on our list. 

Brink’s Stainless Steel Discus Padlock also features a full-radius rubber bumper which is also unique to our list of locks. This bumper adds an extra layer of protection. And, it also prevents unsightly scratches and dings. 

Master Lock Magnum M175XDLF Outdoor Combination Lock:

Best Weatherproof Lock:


  • Material: Zinc, steel
  • Dimension: 1 x 3.88 x 6.25 inches
  • Weight: ‎0.5 Pounds

Unique Features:

  • Heavy-duty, weatherproof lock
  • Resettable combination 


  • Easy to set and reset combination
  • Tough-Cut octagonal boron-carbide shackle 


  • You need to manually scramble the numbers after you lock it.
  • Poor combination design.

If you are a fan of brass locks, this is it! The only brass-made lock on our list, that is budget-friendly, weatherproof, and strong.

Like the other Master Lock Combination Padlock, it is also a keyless combination lock. But it is made from brass and the combination lock uses four-digit numbers. The previous two locks we have featured in this list are not good for outdoor use, as they are not weatherproof. 

If you need a lock to withstand heat and rainfall, this is it. Not to mention, the one-directional dial feature comes in handy when you’re in low-light situations.

In terms of price, it will not break the bank. In fact, it only costs slightly higher than the Brinks Discus lock

Built to last, the Master Lock Magnum padlock boasts a zinc body and a reinforced body bumper for extra strength and reliability. None of the locks on our list are made from brass, which can be sturdier than steel. 

The shackle seal and covered dials provide superior weather protection, making it ideal for outdoor use. Only the ABUS Granit has more weather protection than the Master Lock Magnum. 

But what really sets this lock apart is its tough-cut octagonal boron-carbide shackle. It’s 50% harder than hardened steel, making it extremely resistant to picking and prying. 

Because this lock has great weatherproof abilities, it is ideal to use outdoors. Especially, if you have a pod, it can be one of the best locks for pods

ABUS 37/80 Granit:

Overall Best Lock:


  • Material: ‎Alloy Steel, Aluminum, Brass, Steel
  • Dimension: ‎3.09 x 1.53 x 3.06 inches
  • Weight: 2.4 Pounds

If you want the best possible security there is, we highly recommend the Abus 37/80 Granit. This is the best lock in our list, we saved the best for last. It is crafted from hardened alloy steel and designed to withstand even the most determined burglars. 

The ABUS Granit is the most expensive lock on our list, it costs about 20 times more than the previous two. But we think that’s worth the price because you will be getting what you will pay for.

The other locks in our list don’t even compare to this beast. This lock beats every other common lock in everything. Be it security, material, weatherproof, you name it and this lock is best at it. Wanna see a lock picker go at the ABUS Granit? Here is the video for you-

Ubox Lock Buying Guide

When it comes to selecting a lock for your Ubox, it’s important to consider various factors. We will delve into each of these aspects to help you make an informed decision.


Before you dive into the world of Ubox locks, it’s essential to determine the compatibility between the lock and your storage unit. Uboxes come in various sizes and designs, so it’s crucial to choose a lock that fits seamlessly with your specific Ubox model. 

This ensures a snug fit and prevents any vulnerabilities that may compromise the security of your belongings. 

Additionally, considering the dimensions of the lock and its compatibility with other security features, such as latch mechanisms or security bars, is also vital.


The security of a lock is dependent on how well it’s made. Also, the construction directly impacts its durability and strength. Opting for a lock that is well-constructed ensures its ability to withstand external forces. This includes attempted break-ins or harsh weather conditions. 

Lock Type:

Locks come in various types, each with its own unique mechanism. Understanding the different lock types can help you choose one that suits your preferences and specific security needs. Let’s explore some of the common lock types that are suitable for Pelican cases:

  • Padlocks: Padlocks are the most common and widely used but they can be very easy to break. 
  • Disc Locks: Disc locks are specifically designed for self-storage units like Uboxes. 
  • Cylinder Locks: Cylinder locks, also known as barrel locks or cam locks, are commonly found in storage facilities. 

But if you are looking for locks to use in your residence, smart locks with a home assistant would be the perfect choice. 


The material used in the construction of a lock greatly influences its strength and level of protection. Go for locks made from high-quality materials that can withstand external elements and resist tampering. 

Hardened steel is a popular choice due to its strength and resistance to cutting or drilling attempts. Solid brass is another excellent option, as it offers durability and corrosion resistance.

Additionally, locks with protective coatings, such as chrome plating or weather-resistant finishes, provide added durability and protection against rust or wear.

Frequently Asked Questions (FAQs):

Are disc locks better than padlocks? 

Yes, disc locks are generally considered to be more secure than padlocks. The rounded shape of the shackle on disc locks makes it challenging for bolt cutters to cut through. The shackle of disc locks is closed, so only a small portion of it is exposed. This further reduces the risk of tampering or cutting. 

What padlock Cannot be cut? 

Shackleless padlocks are almost impossible to cut or breakthrough. Despite the name, shackleless padlocks do have a shackle. However, it is fully enclosed and concealed within the steel body of the lock. With this design, potential intruders can’t tamper with or cut the shackle.

Can a hammer break a padlock?

Yes, a hammer can potentially break a standard padlock, especially if it is used forcefully and repeatedly. Padlocks, while providing a certain level of security, can still be susceptible to forceful attacks. A strong impact from a hammer can damage the locking mechanism, the shackle, or even the body of the padlock.
