Untouchable Container Lock Security

This container lock's internal locking anatomy is completely hidden away from a would-be thief. There is nothing for a thief to focus on in his attempt to use a bolt cutter.

The Intermodal Barrier Lock Is The Toughest Lock You Can Find

The Intermodal Barrier lock is specifically designed to withstand attempted forced entry into a container. Don't take our word for it; take a few swings at the lock yourself. Secure this lock on your container, grab a sledgehammer, and then go to town! This lock is indestructible. IR-20 Withstands Attacks

Cylinder Disk Locking Mechanism

As with all of our locks, the IR-20's locking mechanism is nearly impossible for a thief to pick. This container lock is made with nine cylindrical disks. Furthermore, WAR-LOK cuts all keys in-house, and management has to approve key replacements.

Customer Reviews

I bought 2 of these to secure a shipping container a couple years ago. I had such a great experience with them that I purchased 4 more recently. They are great.


We lost two trucks to theft about two years ago. We purchased spring brake locks. king pin locks, glad hand locks, and container hasp protectors. Small investment to protect from another loss. We've had one other attempt. There was some damage to a set of air brake valves but the truck was still here. We keep our spare tires in a spare trailer and a cargo container; with the Warloc lock protecting them. There were visible signs of an attempt to get in...but the Warloc held them off.


Very secure product, easy to use, the keys have a serial number so you can re-order spares.


This lock is the only lock that works! I've had others cut through. sawed through and had a grinder go though another Once the Intermodal was installed it all stopped
