LifeLong Locks have a patented ball-bearing locking system and are made from solid stainless steel. That makes them the strongest locks on the market. But our strength doesn't end there. Each LifeLong Lock is engineered with an anti-drill ball and unique oval key design that makes it practically theft-proof.

In product performance tests against competitors, LifeLong Locks were proven to be the strongest on the market, withstanding significantly more pressure in "peak load to failure" tests*. Once the locks were bent from the peak load pressure, a full five out of five LifeLong Locks tested were not removable, protecting the trailer even when damaged. This testing confirmed that LifeLong Locks are the strongest and most theft-proof trailer locks you can buy.
