A Little Background

There are all kinds of home security systems such as the Apple homekit or the Kwikset Smartkey that help you secure important items as well as interiors such as computers, gun, valuables, expensive paintings, etc. And padlocks are a part of such extensive security systems. Padlocks aren’t easy to design though. Nor are they easy to choose when you want to keep your property safe from intruders and other kinds of danger. For example, if you have a car gun safe for security purposes, you’d want a durable padlock to keep it from getting in the wrong hands, right?  So, what goes behind the mechanism of padlocks?

The most durable padlocks are made of solid metal materials, a locking system, and a shackle. This is what a best padlock constitutes of. There’s no room for a weak spot in a padlock be it the locking mechanism, locking bar, shank, or the padlock’s body. Engineers design padlocks to ensure it’s simple to lock and unlock for consumers. The sole purpose of a padlock is to keep something secure. Be it your home, office space, a shop, or any other commercial or residential property. It can literally be a life-saver. Hence, buying the best padlock is not complete without careful research and comparison. That’s what we’re here for!

Padlocks come in a wide array of shapes. Regardless of the design of the padlock, the operation of each is the same. The disc mechanism of the padlock is influenced when the total size of the apparatus increases. As a result, the keyway and the locking mechanism also increases in size. Keeping the shackle or shank and the locking bar intact. These two features of a padlock contain spring loaded pins. Once you insert the key into the padlock, the different springs inside the locking system align themselves to the right pattern to allow the locking bar to open. Once it is aligned, you rotate the key in the right direction and unlock the shank easily. If it isn’t aligned, which means it’s the wrong key, the shank stays locked and impossible to open.

A different kind of padlock is designed in such a way that the shank pops out when the shank is opened with the right spring alignment. Contrarily, some padlocks require you to manually open the shank away from the locking mechanism with the right key-to-locking bar alignment. There are mini padlocks as well, with a much smaller body and longer shank, like the Kryptonite New York Fahgettaboudit. Just like that, there are all kinds of padlocks to look forward to, but with the same operation. (1)

Types of Padlocks

A padlock can be made a part of your home security system. And to help you choose the right product, here are the different types of padlocks to look for when choosing the best possible option for you.  (2)

Closed Shackle Padlock

This is the most common type of padlock there is on the market. The top half of the shank is protected by the padlock’s body making it difficult to cut through or break with bolt cutters. It’s a standard design which most insurance companies allow as it as a minimum security requirement. This kind of design also decreases clearance between the opening of the shackle and the shackle itself. This makes it one of the best anti-theft protection devices on the market like the kryptonite kryptolok. Which means you can lock almost any bar, cable, handle, or hole with the help of a closed shackle padlock.

Straight Shackle Padlock

With a straight shackle padlock, you can lock steel shutter doors easily. They can also be used to secure shipping containers or roller-shutter containers and doors. These are probably the most easy to use padlocks on the market. Plus, they’re more affordable than closed shackle padlocks. These come second to closed shackle devices as being the commonest padlocks used by consumers.

Round or Circular Shackle Padlock

By the looks of it, a circular shackle is round and has a curved axis. It gets its appearance from a closed shackle padlock making it difficult to break with bolt cutters. Compared to standard padlocks, round padlocks aren’t suitable for all types of devices. With the keyway positioned in the center of the padlock and not next to the shackles, this can be a bit of a disappointment for many. However, this kind of design is almost impossible to break because drilling into the keyway or using a barrel to force it open is practically impossible. For this feature alone, many high-end consumers prefer using a round circular shackle padlock. It’s also good for protecting your higher-priced purchases such as your bike, trunk, etc.

Long Shackle Padlock

These have a more extended shackle in the shape of a ‘U’; just like the ABUS Granit X-Plus series.  This is to increase the locking area for bars, rods, handles, etc. It is one of the reasons why long shackle padlocks are a popular choice.

For smaller bikes, a mini U-lock is what most people search for. This type of bike lock offers plenty of locking space and are secure and rugged. The only drawback to using long shackle padlocks is that it exposes the shank to bolt cutters, saw, or other tools that could easily break the shackle. The best use for a long shackle padlock would be to use a long chain. The chain lock pulls the weight down making it more difficult for intruders to try and open or break the lock.

Other types of locks also prevalent in the industry are smart locks, folding locks, shackle locks and chain-based locks.

How We Picked

The best smart padlock is bought based on your preferences. However, picking the most high-end one could take hours if you want it for high-end security reasons. Most padlocks are spring loaded which means they come with a series of combinations that allow the key to properly open the locking mechanism. This allows the key to rotate easily without restriction, which opens the shackle. If you use a standard lock pin mechanism, chances are you’re exposing intruders to the most sure-fire way into breaking in the padlock.

With a more sophisticated and rugged padlock, however, there’s no scope for damage or a break-in. All you need is a set of specialized lock picks to break open a shackle and untangle the locking mechanism.

As a strict response to this problem, manufacturers as reputable as ABUS have development new-fangled technology to ensure break-ins don’t happen. This means adopting the technology of rotating disks rather than locking pins as their front locking mechanism. This means, no matter how hard you try, you won’t be able to break-in the padlock by specialized lock-picking tools.

The body of the padlock is where the keyway is placed. This is usually built in brass or steel or chrome material, making it a rugged and longer-lasting choice for many.

Brass

A brass constructed padlock is cheaper to make and is a more affordable option for consumers. If you want low security, opting for a brass padlock is a good way to go. However, if you want high-end security, you should know that brass can be easily drilled into making it a danger risk for top-end lines.

Steel Alloy

Steel alloy padlocks are rugged and take much longer to manufacture. Most of the top-end components of a padlock are made up steel. This includes the locking bar, keyway, locking points, and the shackle. The locking mechanism, too, is made up of steel. It provides exceptional protection again drilling. It also helps against rusting or corrosion, which is a huge advantage for most people.

There are two main variations to steel padlocks: pressed steel and lamented steel.

Pressed steel padlocks are generally used as best-lock construction toys that come as luggage locks. They offer standard level of security for smaller items.

Lamented steel padlocks are designed by pressing into pre-punched thin steel plates. These plates are then folded in together until they make a solid block. These types of padlocks can be used for standard security purposes.

The shackle is the second most important part of a padlock. It is built with stainless steel or hardened alloy. The other thing to consider about the shackle is its shape. Most shackles are round or in a ‘U’ shape.

Stainless Steel

A stainless steel shackle is hardened steel which is the standard for most outdoor padlocks. They provide a good enough surface to resist corrosion, drilling, cutting, and other attacks.

Hardened Alloy

Hardened alloy shackles are used for high-end security reasons. They are often heat treated to increase durability and resistive properties. Plus, they’re the only sturdy and reliable shackles that can resist drilling attacks. Many hardened alloy shackles are further hardened for a chrome or metallic finish.

Our Best Pick

Frequently Asked Questions

Q. What are the levels of security padlocks offer?

A. Most modern padlocks offer multiple levels of security backed by trademark laws and security ratings. However, there is no single universal security standard for padlocks to fall back on. In such a case, if your padlock manufacturer offers security levels from 1 to 20, it must be taken plainly. There are certain kinds of standard padlocks which are not suitable for locking larger items. For bikes, for example, a proper bike lock like the Fahgettaboudit Mini bike lock will be important.

That said, for high-end padlocks, you can rely on the following padlock security ratings. They are:

CEN security ratings: Padlocks are divided into CEN 3 to CEN 6 – CEN 6 being the highest form of security a padlock can provide. These are categories into which padlocks are divided based on how they shape out after certain attack tests. (3)

Sold Secure security ratings: Padlocks in this category are divided into gold, silver, and bronze categories. Gold being the highest form of security a padlock can provide. Each padlock is tested and labeled into a category based on it performs against harsh attacks such as drilling, pulling, and other physical attacks. (4)

Q. Which is best – a combination padlock or a key padlock?

A. This is one of the most common questions asked by consumers. A good answer would be that key padlocks are tougher than combination padlocks, especially best used for high-end security purposes. The mechanism of a combination padlock suits smaller purposes such as lockers, gym bags, bike, etc. This is because a combination padlock can be cracked, rather extensively, by trying each code.

According to our tests, a combination padlock can be cracked within 4 to 5 hours for a 4-dial lock. As for a 3-dial lock, it can be cracked in less than an hour. Hence, setting up a combination lock in a remote location is a strict no. When you’re considering a more higher security end lock, a key padlock is the best option to move forward with. (5)

Q. What are keyed alike and master keyed padlocks?

A. A keyed alike padlock has the same key for multiple padlocks. What this means is that you have multiple padlocks in front of you and each one of them can be opened by a universal key. Keyed alike padlocks are also popularly known as suited padlocks or same key padlocks. These are more practical than other types of padlocks, hence, they’re more in demand for high-end security purposes.

A master keyed padlock is quite dissimilar to keyed alike padlocks. For one, they contain a master key which is a part of a whole set that can open multiple padlocks. The larger set of keys are allotted to each padlock and in return the master key can be used to open each and every one of those padlocks. A master key is best for authorised users only, meanwhile, the larger set of keys can be distributed to people in charge. Master keyed padlocks are more expensive than keyed alike padlocks because of their complex design and usage. When you want high-end business security with a group of people involved in the team, a master keyed padlock is your best option.

The most common usage for master keyed locks include for schools, universities, gyms, and such. And the best brand that manufactures such master keyed padlocks is ABUS.

Q. Which is the best padlock lubricant for safekeeping?

A. Our answer, based on research and testing, would be graphite powder. It makes an excellent lubricant for cold weather as padlocks are prone to freezing. However, graphite powder is a good lubricant for the cold weather only. For more humid climates, graphite could make the padlock too greasy and sticky, which is never good. You should know that grease is the number one kryptonite of padlocks; even more harmful than rust. The best lubricant for all seasons, that is if graphite is too difficult to use in the winter, is oil-based lubricant. The best oil-based lubricants offer better protection against rust and stickiness. They help keep the lock intact and last for a long time. An angle grinder works well with such oil-based lubricants.
