The 5 Best Padlocks [Ranked]

In this post, we examined five of the best-selling padlocks.

Padlocks are small locks that have been in use for centuries to help secure belongings and keep out intruders (Source).


How do they work?

Most padlocks use a key to open, while others rely on a combination system. Combination locks use a wheel that drives a cam.

This turning allows a drive pin to make contact with the wheel fly on the nearest wheel. Once you turn the dial in the correct combination, the lock opens.

A key padlock uses a pin and tumbler system.

The teeth and notches of the key move the spring-loaded pins within the lock to open it. Modern locks now use technology such as Bluetooth to open (Source).

Before buying a padlock, experts recommend taking an inventory of the items you wish to secure and determine their value.

The higher the value, the better the lock you’ll want to buy. Another thing to consider is your insurance. Some insurers specify that a lock must meet a specific rating when it comes to whether they’ll insure your valuables (Source).

Like the other locks, this is ideal for securing everyday items like backpacks, trunks, and lockers. The 4-pin cylinder makes it resistant to picking, and it comes with two keys.

  • Master Lock’s 1-3/16 inch padlocks also feature their vinyl coating over their aluminum core. This pack comes with four locks that are unlocked via a key. Like the previous models, these locks are ideal for securing smaller, less valuable items such as you would store in a locker, backpack, or trunk.

Reddit Tips

Hardest To Break?

Over in Reddit one user wondered which padlocks with the same key are the hardest to break?

This college student was interested because he lives out of his backpack and wanted to purchase and especially secure combination style option to use at a gym. A user recommended high-security options (from Home Depot & Walmart)- saying that in general the more you spend a better quality that you’ll get.

Another rule of thumb, when you end up purchasing shouldn’t cost more than what you are protecting with it.

For example, if your safeguarding pricey electronics equipment or ultra expensive Apple products, it makes sense to purchase something that costs over $200.

But if you’re locking away some old gym clothes and scratched CDs, then it doesn’t really make sense to spend too much money on one.

One user did recommend the Master Lock speed dial, though he also liked Keyed Alike products.

They even recommended an aftermarket modification- adding some epoxy onto the one-way screw on the back. He even says that professional lock picker is haven’t found a way to bypass it, at least without destroying it.

That said, thieves aren’t going to spend a lot of time picking a lock if they can just destroy it. This user also said that because this particular style of lock is not especially heavy duty or rugged, and has a pin shackle, in all likelihood if someone attacked it with a small bolt cutter or hammer it would probably break.

He recommends purchasing options that have hardened thick shackles and not to be as concerned with pickability.

Another user asked where the original poster was located. He says that, surprisingly, a bunch of different locks are only available for purchase and specific countries.

For example, he purchased a ABUS Titalium 80TI/40 with a keyway and its enhanced internal security mechanisms that are great at preventing that. But make sure you don’t forget the key- otherwise you might need to use a right angle drill to break it open!

Inexpensive Options?

Another poster wondered whether you could find a high-quality padlock for cheap.

In his particular case, he is traveling internationally with some pricey firearms and needs to store them in a hard-sided, locked case. One of the top recommendations was the non-shimmable American 1100.

Because this particular brand of lock has an especially thick shackle, it would force thieves or the TSA to actually destroy the case itself rather than attempt to break through the lock. Another useful suggestion came from a user who said that to make it extra tamper-proof, you could add a  tamper sticker to it.

Weather Resistant?

Over in the buyitforlife section of Reddit, someone was looking for a high-quality option that would be weather resistant.

He was looking to help to secure down a ladder outside so it would need to be able to withstand harsh and inclement weather.

The top advice came from somebody that said that it’s not worth paying too much for one because they don’t provide true security if a thief is determined to steal your ladder.

His recommendation was to visit your local hardware store and purchase an option with a thick shackle because that would provide the best protection at the lowest cost.

On the other hand, if you are looking for a higher grade level of security that would be pretty hard to saw through or cut, he recommended Medeco shrouded padlocks. Another user offered some surprising criticism of Master Lock, saying that the majority of them can be popped right open with correctly placed hammer strikes.

A professional locksmith suggested the Ace Hardware brand locks with a brass body.

There was even a person that advertised themselves as an ‘urban asset liberation specialist’ – in short, a thief. He said that the majority of padlocks are merely an annoying deterrence and not true safeguards of material possessions to a dedicated thief.
