Choosing the Best Lock to Keep Your Shipping Container Secure

Added: 05/08/2024

Padlocks

Standard padlocks are a versatile type of lock that can be used to secure shipping containers. When choosing the best padlock for a shipping container, it’s advisable to opt for a high-security model rather than something that’s cheaper and simpler. Padlocks tend to be made of hardened steel or brass, and those with a thicker shackle can be more resistant to cutting. They tend to be a more affordable and widely available option but can be more vulnerable to tools like bolt cutters than a specialized container lock. 

CISA container locks

CISA container locks are specifically designed for high-security needs and are among the most secure locks for shipping containers. They feature a robust design that is resistant to tampering and forced entry and are usually made of hardened steel or a strong alloy. The locking mechanism is often a more complex system that’s difficult to duplicate, but it can be more expensive than normal padlocks.

Shipping container lock boxes

Lock boxes provide an added layer of security by encasing the padlock with a thick steel box that is difficult to cut through. The steel box has a lock of its own, making it more challenging for thieves to tamper with the base padlock. The downside is shipping container lock boxes can be cumbersome, adding bulk and weight to the doors of your container.

Twist locks

Twist locks are commonly used on shipping containers to secure the cargo during transit, but they can also serve as an effective security measure when combined with other locking mechanisms. Twist locks use a rotating mechanism to secure the container doors so they stay closed, and are made from heavy-duty steel. For security they're often used in conjunction with other locks rather than as a stand alone measure.

Cargo door locks

Cargo door locks are designed to secure the doors of shipping containers and keep them closed. They come in various styles including hasp locks and cam locks. Hasp locks secure the door by latching through a metal hasp and locking it in place with a padlock, while cam locks utilize a rotating mechanism to secure the door. The downside of cargo door locks is they require installation and regular maintenance and could be bypassed if not used alongside other security measures.

Summing it up

The best way to lock your shipping container will depend on your specific needs, budget, and the level of security required. It involves selecting the right combination of locks and security measures to thwart would-be thieves and keep your cargo safe. If you want to achieve the highest level of security, it’s best to consider using multiple layers of protection, such as combining a high security padlock with a lock box, or a specialist CISA lock with twist locks.
