Best Padlock for Storage Unit—Tips & Options

When securing a storage unit, choosing the right padlock is crucial for protecting your belongings. This guide will help you navigate the options to find the best padlock that suits your needs, prioritising security, durability, and cost-effectiveness.

Padlock locking storage

Long ago, in 500 BC the Roman merchants used padlocks while traveling the ancient trade routes to Asia. Since then, the basic concept and design have changed very little.

Ancient Roman lock

It uses a locking mechanism that secures a shackle (the U-shaped bar) into the lock's body. When a key or combination is used, it triggers a series of internal springs and pins (in keyed padlocks) or dials (in combination locks) that align to unlock the shackle.

How are padlocks used?

Padlocks provide an easy and versatile method for securing various items at home or work. Small padlocks are great for securing personal lockers or drawers, ensuring quick and straightforward access.

If you need to secure sheds, garages, trailers, sheds, or a gate, you may need to spend a little more money on a better lock. For high-security needs, a robust padlock combined with a hasp can offer strong protection.

Matching the padlock to your storage unit

Before buying a padlock, consider what you're securing in the storage unit. If you're storing valuable items—like electronics, antiques, or important documents— a high-security padlock is recommended. For less valuable items, a standard padlock might suffice.

8 Types of padlocks

Keyed padlocks: These are traditional locks that use a key to open. They are generally very durable and offer a range of security features depending on the price. Look for models with a hardened steel shackle and anti-pick pins for increased security.

Combination lock

Combination locks: These locks do not require a key and can be convenient if you tend to lose keys. However, they are often easier to breach than keyed locks, so choose a model with a robust mechanism and avoid those with simple combinations.

Disc locks: Especially popular for storage units due to their design, disc locks offer enhanced protection against bolt cutters and other tools. Their rounded shape and minimal shackle exposure make them a top choice for storage security.

Electronic padlock

Electronic locks: These utilise technology such as fingerprint sensors or digital keypads. While convenient, they depend on batteries and may not be suitable for all outdoor environments, especially in cold or very wet conditions.

Weatherproof padlocks: These are designed to withstand harsh environmental conditions like rain, snow, and extreme temperatures. They typically feature a protective covering that guards against rust and corrosion.

Shrouded padlocks: This type has an extended guard around the shackle, providing extra protection against bolt cutters. Shrouded padlocks are often used in high-security areas where the risk of tampering is significant.

Keyed alike padlocks: These are useful for situations where multiple locks are needed, and it’s convenient to open them all with the same key. This is commonly used in business operations where multiple pieces of equipment or doors need securing.

Interchangeable core padlock

Interchangeable core padlocks: These allow you to change the lock core without replacing the entire padlock. This feature is beneficial for businesses that need to change locks frequently due to security concerns or lost keys.

Considerations for choosing a padlock

Shackle size and material –The shackle is the U-shaped bar of the lock. A thicker, shorter shackle provides more resistance to tools like bolt cutters.

Lock body construction – Look for locks made from hardened steel or other durable materials that can withstand attempts to break or drill.

Weather resistance – If your storage unit is outdoors, ensure the padlock is weatherproof to prevent rusting and corrosion, which could weaken the lock.
