Shipping Container Locks

Keep your shipping container safe with a heavy duty shipping container lock from Cargostore. As a supplier of ISO and DNV shipping containers, we know all about keeping your cargo safe. There are a lot of different locks available on the market, so this is the one that we recommend. 

However, even a heavy duty padlock can be cut with the right tools. That’s why we also offer advanced container security options including lock boxes, alarms and lighting.

How to Lock Your Container – a Step by Step Guide


How to close and lock your doors


  • Start by closing the left-hand door
  • Make sure the locking bars go into their locking keepers at the top and bottom of the container
  • Engage the cams and keepers and then twist both handles
  • Put the handles into the mounts and close the locking lapses
  • Repeat the process with the right hand door
  • Slide the shackle of your lock closed on the locking bar to secure
  • You should now not be able to turn or open the locking bar

Heavy Duty Container Lock


Normal padlocks may look chunky, but can be removed with surprising ease. A thief armed with bolt cutters can cut through a common padlock in less than 20 seconds.

For peace of mind, you need a secure, super heavy duty padlock made of solid hardened steel from Cargostore.

Designed to resist sawing, prying and rust, the shackle for these locks is harder and more shielded than on a typical padlock, making them far more difficult to get at with bolt cutters.

We can supply these padlocks upon request. Simply ask us for them when you are ordering your next container.

Container Lock Boxes


You can also choose to add an extra layer of security by having a container lock box installed. This is a steel box which is securely welded to the container and encloses your padlock so it can only be accessed from the underside.

Lock boxes prevent thieves from forcing open or cutting through the padlock using crow bars, angle grinders or bolt cutters, as well as shielding your padlock from the elements.

Thieves know that lock boxes require a huge amount of effort to circumvent, so they act as an excellent deterrent against burglary. Our lock boxes are welded to the container, so please order prior to delivery.



Using the Lock Box correctly


  • Make sure you close the doors fully by following the instructions above
  • Unlock your heavy duty padlock, and pull the spindle out.
  • Insert the padlock up into the lockbox, and make sure it goes around the locking pin.
  • Push the padlock spindle through the locking pin, turn the key and remove in order secure the padlock.
