Types Of Shipping Container Locks
1. Padlocks

Padlocks are the most common choice for locking shipping containers (image courtesy of Yale).
They’re usually made of tough steel with a U-shaped design that hooks into a lockbox. While they do the job, basic padlocks can still be cut with bolt cutters.
2. Hidden Shackle Padlocks

The shackle (the part that could be cut) is hidden inside the lock, which makes it hard for thieves to mess with (image courtesy of All Padlocks).
They work best with matching hasps, though installing them might involve welding. If you’re securing valuable items, this lock is worth the effort.
3. Crossbar Locks

Crossbar locks cover the container’s handles with a heavy-duty steel bar that can’t be easily cut or picked (image courtesy from Evergreen Hatch Works).
They’re great for keeping doors secure. Some even come with adjustable bars to fit different-sized handles.
4. Roll Door Locks
Got a container with roll-up doors? These locks keep those doors shut tight when not in use. They’re easy to install and provide solid security without making it hard to open the container when you need to.
5. Twist Locks

Twist locks are less about theft and more about stability (image courtesy from All Things Containers).
They’re used to connect containers stacked on top of each other or side by side. You twist them into place to keep containers secure during transport or storage.
6. Lockboxes
A lockbox is like armor for your padlock. It’s welded onto the container door and hides the padlock inside, keeping it safe from bolt cutters or tampering.
7. Latch Guards

Latch guards are simple but effective (image courtesy from Doorware).
They’re flat metal plates that cover the container’s latches and block access from the outside. They bolt from the inside, so once they’re on, the latch is off-limits to intruders.

8. Inner Bolt Locks

Inner bolt locks work from the inside (image courtesy from Walmart).
They bolt the container shut, which makes it impossible to open from the outside without unbolting it first. Combine these with a padlock or crossbar lock to double the security.
9. Keypad Entry Locks

If you want to skip the keys, keypad locks let you use a code instead.
They’re handy for container offices or mobile units. Just remember to keep the batteries fresh because you don’t want to be locked out because of a dead keypad!

Factors To Consider When Choosing A Lock

A lockbox instantly doubles the security of your container.
- Security Level: Think about how much security you actually need. If the area or the purpose of the door demands high protection, look for locks with advanced features like anti-pick pins and heavy-duty materials.
- Type of Door: Not all locks fit every door. For example, solid doors (like wood or metal) usually need deadbolts to stay secure.
- Ease of Use: Pick a lock that’s easy for everyone authorized to use. Complicated locks can lead to frustration - or worse, people might stop using them properly and weaken security.
- Durability: The lock should handle frequent use and stand up to the weather without wearing out quickly.
- Budget: Know your budget beforehand. High-security locks can cost more, but there are solid, budget-friendly options that provide great protection without overspending.
- Accessibility and Key Control: Think about who will need access. Will you need a master key system, keyless entry, or limited key duplication? It’s worth planning for easy rekeying in case keys are lost.
- Local Crime Rates: Check crime stats in your area. If you live in a high-crime zone, it’s worth investing in stronger locks. If not, standard locks might do the job just fine.

Frequently Asked Questions (FAQs)
- Why is lock material important?
The material of a lock plays an important role in its durability and security. Locks made from hardened steel or other strong materials are more resistant to cutting and tampering. Plus, the material can also impact the lock's resistance to environmental factors like rust and corrosion.
- Are padlocks sufficient for securing my container?
Although padlocks provide a simple degree of protection, they are susceptible to incisions and picking. To improve security, please consider high-security locks or a lockbox that shields the padlock from prying.
- What should I do if I lose my keys?
You can contact a locksmith who can help you access the container without causing any damage to it.
- Are electronic locks reliable for shipping containers?
Electronic locks can be very reliable and provide advanced features such as keyless entry and remote access. However, they require battery maintenance and should be tested regularly to maintain functionality.
