How to Pick the Best Padlock? Guide

How to Pick the Best Padlock

Padlocks are a type of lock that is both portable and removable. A traditional padlock features a shackle which is passed through a hole, staple, or chain, and secured. These padlocks help to provide security for both commercial and residential uses.

Currently, there are plenty of padlocks available on the market. Choosing the best padlock requires considering several key factors to ensure you select a lock that best meets your security needs. Below are some essential considerations when picking a padlock.

What to look for


Consider security needs

Before deciding on what typic of padlock to buy, make sure to consider any security needs. What is the padlock supposed to protect? What is the value of the item that is being protected by the padlock? Does the locking device match the security and strength of the padlock? What about the level of risk in the environment? Buyers should keep these questions in mind when thinking about buying a padlock. They can look for padlocks with high-quality materials and other security features, such as hardened shackles, anti-pick mechanisms, drill resistant construction, and those with a separate key.

Choice of metal

Buyers should also consider the metals the padlock is made of. The type of metal can make a huge difference to its durability and functionality. Most padlocks are made from steel and brass, but depending on security needs, they can be made with reinforced metals. For a top-quality padlock, look for stainless and hardened steel, as they are the hardest for thieves to break.

Padlock build quality

Quality is key to picking the best padlock for the job. Opt for ones engineered to withstand brute force. The shackles are often the first point of attack, so buyers should get consider getting heavy duty padlocks. Most high-quality padlocks come with a locking mechanism, although there are different types, including combination locks, padlocks with keys, and electronic locks. Key-operated locks provide traditional security, while combination locks eliminate the need for keys but require users to input a code.

Weather resistant

If the padlock needs to be used outdoors or in harsh environments, buyers should opt for a weather-resistant lock. Make sure to look for features such as corrosion-resistant materials, protective coatings, and rubber seals to prevent moisture and debris from compromising the padlock’s functionality.

Level of security

Level of security

Each kind of lock has a level of security that determines what applications they are best suited for. Consider the function of the lock before deciding on what level of security is best. Levels of security are typically categorised by locking grades. For instance, grade 1 usually offers the highest level of safety.

Key control and duplication

Consider the key control and duplication policies associated with the padlock. Som brands offer restricted key systems that require some form of authorisation for key duplication. This helps to enhance security by reducing the risk of unauthorised key copies.


Although price should not be the sole determining factor when it comes to picking a suitable padlock, buyers should still consider their budget when choosing one. Aim for the best value within your price range, and make sure to balance security features with durability and quality to get the most out of the padlock.

Types of padlocks

Types of padlocks

Below, we have broken down a few of the main types of padlocks and what they are best suited for. Make sure to keep reading to learn more about them.

Combination padlocks

They are a popular choice for padlocks. These locks typically come in two forms – a circular combination and a ¾ digit spin dial. There is no key – instead it uses a digit code placed in sequential order to unlock the shackle. Combination padlocks typically are best suited to secure low-value or low theft risk items such as cupboards, toolboxes, lockers, and bicycles.

TSA padlocks

TSA (Transportation Security Administration) padlocks are suitable for all bags, luggage, and suitcases. This makes them necessary when travelling by air, with a few countries (such as the US< Canada, Japan and South Korea) requiring travellers to use this lock. This type of padlock allows airport security to screen all passengers’ luggage before loading them on the plane. Airport security can also safely unlock a luggage using a TSA master key in case there is need for closer inspections.

Weather-resistant padlocks

Weather resistant padlocks

Much as its name suggests, these padlocks are great for use in harsh outdoor environments. They are considered heavy duty padlocks and have corrosion-resistant internal components. Shackles and bodies typically use weather-resistant materials such as brass, laminated steel, or aluminium stainless steel. Some padlocks may even come with a plastic or vinyl jacket for extra protection from dirt and moisture. These padlocks are best suited for boats, ships, industrial plants, containers, and other locations close to the sea.

Monoblock padlocks

Monoblock padlocks are shaped like a rectangle. They are mainly used in commercial and industrial applications. The padlocks feature a straight-line shackle, making it ideal for resisting any cutting attacks. Monoblock padlocks are great for securing valuables or goods that are valuable and at a high risk of theft. Some things that can be secured by this kind of lock include roller shutters, gates, shipping containers and trucks.

Disc padlocks

As the name suggests, a disc padlock is in the shape of a disc. The closed shackle is slightly curved, meaning it is perfect for resisting bolt-cutter attacks. As a result of the shackle length, disc padlocks only provide the user with a small opening. This means buyers must do their research to make sure it fits with their security requirements. Some things that disc padlocks can help secure include storage units, trucks and garage doors.

Closed shackle padlocks

Closed shackle padlocks are a great option if a buyer is looking to minimise the exposure of the shackle. These types of padlocks are highly resistant to bolt-cutters and are often found on shipping containers and in other industrial settings. That said, care is required to handle them – because once it is unlocked, the shackle will completely disconnect from the body. The padlocks typically meet industry standards for durability and strength and are compatible with most restricted keying systems.

Bottom line


By considering these factors, buyers can make an informed decision when selecting the best padlock for their security needs. It is vital to remember investing that investing in a high-quality padlock is crucial for protecting any belongings and ensuring peace of mind knowing items are safe and secure.
