How To Choose The Best Weatherproof Padlock?

Choosing the best padlock depends as much on your personal need and requirement as it depends on essential and additional features.

The following are some questions that you can ask yourself before selecting the most suitable padlock.

  • Where you will be going to use it? Gate, employee lockers, gym lockers, bikes, or any other place.
  • How much you are willing to invest in the padlock?
  • What mechanism do you prefer the most?
  • If you are looking for an indoor or an outdoor lock?
  • What kind of shackles do you prefer the most?
  • If you are looking for a key, pad, or a combination of both when it comes to locking mechanisms.
  • What size is the best suitable for you?

Features To Look For In A Weatherproof Padlock

Whether you are looking for an upgrade or this is your first time finding a padlock, we have created a comprehensive guide to help you.

Here are a few things you need to understand to make an informed decision.

Construction Material

Weather protection padlocks are often made using components and materials such as thermoplastic encased brass, aluminum, stainless or sheathed steel, or laminated steel padlock bodies.

The selection of the materials that are used in the manufacturing of padlocks decides the amount of protection against the elements that come with potential chances of damage.

Additionally, the excellent choice of materials will have a direct influence on the cost of the unit.

Hence, if you want to use your padlock outdoors, where it will be exposed to the elements, then it is imperative that you get one that is built to be weatherproof.

Shackle Type

The hoop-like part that is located at the very top of the lock is called the shackle. Padlocks are classified into three categories depending on their shackle;

  • Open; An open shackle padlock offers ease of use, even in tight spaces like chain links. The exposed shackle, on the other hand, is more subject to manipulation and assaults.
  • Close; A close shackle padlock features built-in shoulders to reduce shackle exposure. It is a more secure padlock than one with a semi-enclosed or open shackle. Close shackle padlocks, on the other hand, have one drawback, size clearance.
  • Semi-enclosed; A semi-enclosed shackle padlock is a middle ground between the two.

When you are shopping for a padlock, you should go for a type in which the shackle is mainly in a protective cover inside the lock. This will provide the highest level of protection.

Keys And Padlock Combination

Traditional lock designs with keys are more common, but a lock with a combination is the best option for circumstances in which more than one person needs access to the same lock.

It also implies that there is no need to have key duplicates made, and there is no risk of losing the key. On the other hand, it is important to make sure that the combination is not forgotten.

If you decide to go with a padlock that has a key, look for one that has at least four tumblers. Tumblers are the pins that prevent the lock from being opened until the correct key is rotated.

The lock is more difficult to pick and it is more difficult to make a copy of the key when there are more pins.

Hence, while looking for a padlock, make sure to get the one that fulfills your maximum security requirement, where you live, and how much protection you need.


A lock that costs just five dollars should be sufficient to protect the data stored in the file cabinet in your home office.

If you have a garage that is full of expensive motorcycles or a shed that is full of power equipment, you should invest in a lock of better quality and spend a little more money.

It’s important to keep in mind that “better” does not always imply “more costly,”.  However, weighing the quality of the lock can help you in finding a great option without compromising on the quality.

Weather Resistance

When searching for the best outdoor weather resistance padlock, the first thing you should think about is whether or not you want the lock to be resistant to harsh weather conditions and other elements.

You don’t need to invest in a padlock that can withstand freezing temperatures if you reside in a dry climate. On the other hand, if you reside in an arid region, the same thing holds for you.

You do not need to be concerned about purchasing a padlock that offers it all. Instead, go for the best choice that fulfills your needs depending on the weather and other factors.

Locking Mechanisms

The wafers or locking pins, the springs, and the keyway design are all part of the padlock’s locking mechanism.

The key patterns of the padlock are determined by the number of pins, their varying lengths, and the design of the keyway.

Padlocks typically come with one of two primary kinds of locking mechanisms. Do you want a lock with a key, or do you want a lock with a combination? Both options come with their own sets of pros and cons.

With keyed locks, if you happen to misplace your key, the only method to get inside the door without having to call a locksmith is to have the lock recut by an expert.

On the other hand, if you go with a combination lock, be sure to choose one that you will always be able to recall if you go that route.

That being said, getting an expensive lock will not ensure you high protection, though a review can. Keeping additional features in consideration, we have created a list of the best weatherproof padlocks for you to choose from.
